Scientists detect an unexpected drop in the magnetic field of a Pulsar

Pulsar V0332+53 is located at a distance of about 22,831 Light Years!

"(Phys.org)—A team of scientists has recently presented evidence of an unexpected drop in the observed magnetic field of an accreting pulsar designated V0332+53. This downturn, observed after the pulsar underwent a bright, three-month-long X-ray outburst, could yield important information on how the accreted mass settling on the surface of a neutron star affects its magnetic field. The findings are detailed in a paper published online on Apr. 26 in the arXiv journal."

The study: An unexpected drop in the magnetic field of the X-ray pulsar V0332+53 after the bright outburst occurred in 2015 | https://arxiv.org/abs/1604.07831

Abstract:
" How the accreted mass settling on the surface of a neutron star affects the topology of the magnetic field and how the secular evolution of the binary system depends on the magnetic field change is still an open issue. We report evidence for a clear drop in the observed magnetic field in the accreting pulsar V0332+53 after undergoing a bright 3-month long X-ray outburst. We determine the field from the position of the fundamental cyclotron line in its X-ray spectrum and relate it to the luminosity. For equal levels of luminosity, in the declining phase we measure a systematically lower value of the cyclotron line energy with respect to the rising phase. This results in a drop of ~1.7 x 10^11 G of the observed field between the onset and the end of the outburst. The settling of the accreted plasma onto the polar cap seems to induce a distortion of the magnetic field lines weakening their intensity along the accretion columns. Therefore the dissipation rate of the magnetic field could be much faster than previously estimated, unless the field is able to restore its original configuration on a time-scale comparable with the outbursts recurrence time. "

Scientists studying this object with NuSTAR originally thought it was a massive black hole, but its X-ray pulse revealed its true pulsar identity. Credit: NASA/JPL-Caltech

How To Make A Mixed Reality Video And Livestream From Two Realities

A mixed reality video is one of the coolest ways to show people what a virtual environment feels like. A green screen makes it easy for a VR-ready PC to automatically remove everything from a camera’s feed, except for your body movements. Those movements are then seamlessly combined with a view from another camera in a virtual environment. As long as the two cameras are synced, you can seamlessly combine views of two realities into a single video. In essence, mixed reality capture is doing what Hollywood or your weatherman has been doing for years, except at a fraction of the cost and in real-time. The end result is almost magical.

* Astronomy and Astrophysics
* Exoplanets
* Planetary Exploration
* Climate and Geoscience
* Astrobiology
* SETI (Search for Extra-Terrestrial Intelligence)

The SETI Institute scientists work within this cross-disciplinary environment and produce world-class research regularly accepted by top scientific journals.

The majority of the work of the SETI Institute happens in this rich research environment. On any given day, our scientists are diving underneath Antarctic ice, mapping the trajectories of asteroids, exploring Mars analogs here on Earth and the geoscience of the real Mars; discovering new exoplanets in the habitable zones of other solar systems; and listening and looking for signs of technological life elsewhere.

Our quest belongs to the world. In addition to sharing our research results with our peer scientific community, the SETI Institute promotes STEM education with programs aimed at inspiring children, young adults and educators. We also bring the results of our work to millions through deft use of social media, radio broadcasting, and publications and presentations made available online to all who want to be part of our search.

Space exploration is an important gateway for children and adults to want to learn about science. The SETI Institute takes full advantage of the fascinating research conducted by our talented scientists to make discovery of life elsewhere in our universe a common purpose and passion of all mankind.___

A burning question...

Is the Universe spatial construct 3 dimensional and not higher because of the maximum initial temperature achieved? According to what scientists have reported in a new study, had the initial temperature been higher before the cooling begun, our Universe could have been of higher spatial dimensions

"(Phys.org)—The question of why space is three-dimensional (3D) and not some other number of dimensions has puzzled philosophers and scientists since ancient Greece. Space-time overall is four-dimensional, or (3 + 1)-dimensional, where time is the fourth dimension. It's well-known that the time dimension is related to the second law of thermodynamics: time has one direction (forward) because entropy (a measure of disorder) never decreases in a closed system such as the universe.

"(Phys.org)—The question of why space is three-dimensional (3D) and not some other number of dimensions has puzzled philosophers and scientists since ancient Greece. Space-time overall is four-dimensional, or (3 + 1)-dimensional, where time is the fourth dimension. It's well-known that the time dimension is related to the second law of thermodynamics: time has one direction (forward) because entropy (a measure of disorder) never decreases in a closed system such as the universe.

In a new paper published in EPL, researchers have proposed that the second law of thermodynamics may also explain why space is 3D.

"A number of researchers in the fields of science and philosophy have addressed the problem of the (3+1)-dimensional nature of space-time by justifying the suitable choice of its dimensionality in order to maintain life, stability and complexity," coauthor Julian Gonzalez-Ayala, at the National Polytechnic Institute in Mexico and the University of Salamanca in Spain, told Phys.org."

The study: Julian Gonzalez-Ayala, Rubén Cordero and F. Angulo-Brown. "Is the (3 + 1)-d nature of the universe a thermodynamic necessity?" EPL. DOI: http://iopscience.iop.org/article/10.1209/0295-5075/113/40006

Abstract
" It is well established that at early times, long before the time of radiation-matter density equality, the universe could have been well described by a spatially flat, radiation only model. In this article we consider the whole primeval universe, as a first approach, as a black-body radiation system in an n-dimensional Euclidean space. We propose that the (3 + 1)-dimensional nature of the universe could be the result of a thermodynamic selection principle stemming from the second law of thermodynamics. In regard to the three spatial dimensions we suggest that they were chosen by means of the minimization of the Helmholtz free energy per hypervolume unit following possibly a kind of broken symmetry process, while the time dimension, as is well known, is related with the principle of increment of entropy for closed systems: the so-called arrow of time. "

(Left) The Helmholtz free energy density (f) reaches its maximum value at a temperature T = 0.93, which occurs when space had n = 3 dimensions. (s and u represent entropy density and internal energy density, respectively.) (Right) Transitions to different dimensions cannot occur below a temperature of 0.93, corresponding to three dimensions.

"In a series of measurements, using wave plates and a polarizing beam splitter the scientists determined the polarization of both red signal photons after passing through the atomic cloud. Thereby they were able to show that the light pulse had picked up an additional phase shift of 180 degrees whenever the signal laser was switched on during the control pulse. The whole cycle – the storage of the control pulse, the propagation of the target pulse and the retrieval of the control excitation – takes only a few microseconds.

"The experiment demonstrates that we can rotate the polarization plane of the photonic qubit in the target pulse with just one control photon," resumes Dr. Dürr.

"The era of individual flight has begun: here is the Flyboard, platform of single pilot Vertical Take Off and Landing flight, propelled by 4 small jet engines (250hp each), with an estimated maximum flight time of about 5 to 8 minutes (much greater then what was achieved by the historic "Rocket Belt" which cannot fly more than 30 to 40 seconds).

To record, the controls are contained in the right hand stick and the fuel tank is inside the backpack."

L'epoca del volo individuale è iniziata: ecco il Flyboard piattaforma di volo VTOL monoposto, propulsa da 4 piccoli reattori (da 250 Hp l'uno) con un'autonomia di volo stimata nell'ordine dei 5/8 minuti (in ordine di grandezza superiore a quello ottenuto dalla storica "Rocket Belt" che non supera i 30/40 secondi di volo).
Per la cronaca i comandi sono contenuti nell'impugnatura della mano destra ed il carburante è contenuto nello zaino.___Share thanks to +Giuseppe De Chiara who also writes:

The harsh reality of virtual reality..

"Virtual reality, oddly enough, isn't immune to the problems that arise in practical reality. Just ask would-be fans of the Oculus Rift headset, many—possibly most—of whom are still waiting for their $600 gadgets more than four weeks after they started shipping .

The delay, naturally, has sparked online grousing and even some data-based activism, including the creation of a crowdsourced spreadsheet for tracking who received their prized VR gear and when. Some longtime supporters of Oculus have declared themselves alienated by the company's inability to deliver; others have defected to rival VR systems, or are at least considering it."

Chromospheric Models and the Oxygen Abundance in Giant Stars

[...]

"CfA astronomers Andrea Dupree, Eugene Avrett, and Bob Kurucz have tacked this fundamental problem with Avrett's PANDORA code for stellar atmospheres. In particular, they include the effects of a hot outer atmosphere in giant stars, something that was typically ignored. Moreover, they do not tie the excitation of oxygen atoms (and the corresponding line strengths) to the local temperature. That constraint, imposed by most previous methods in order to simplify the calculations, does not take more complex situations (like the hot atmosphere) adequately into account.

The astronomers find that their new computations can resolve several outstanding issues. The lines themselves are actually as much as three times stronger than previously thought, reducing the implied oxygen abundances, and thereby also affecting details of the stellar interior models, especially for giants seen in globular clusters of stars. Similar improvements are seen in the results for stars known to be lacking other heavier elements, and even some normal, Sun-like stars. The possible implications extend to estimating more accurately the amount of oxygen present in a solar nebula when exoplanets form."
