The Largest Star Known in the Universe -- A Red Supergiant in Death Throes | Physics-Astronomy

The Largest Star Known in the Universe -- A Red Supergiant in Death Throes | Physics-Astronomy | Astronomy physics and quantum physics | Scoop.it
When the astronomers studied the images of the most massive cluster of stars in our galaxy, Westerlund 1, they spotted something truly unique. Around one of the stars, known as W26, they saw a huge cloud of glowing hydrogen gas, shown as green in this new image above. Such glowing clouds are ionised, meaning that the electrons have been stripped away from the atoms of hydrogen gas. Clouds of this type are rarely found around massive stars and are even rarer around red supergiant stars such as W26, the largest known star in the Universe — this is the first ionised nebula ever discovered around such a star. W26 itself would be too cool to make the gas glow; the astronomers speculate that the source of the ionising radiation may be either hot blue stars elsewhere in the cluster, or possibly a fainter, but much hotter, companion star to W26. The fact that the nebula is ionised will make it considerably easier to study in the future than if it were not ionised.

Hyper-dense Pulsar May Nix Einstein's Theory of Gravity- New NRAO Discovery | Physics-Astronomy

Hyper-dense Pulsar May Nix Einstein's Theory of Gravity- New NRAO Discovery | Physics-Astronomy | Astronomy physics and quantum physics | Scoop.it
A recently discovered arrangement of two white dwarf stars and a super dense pulsar, all filled within a space lesser than the Earth’s orbit around the sun, is allowing astronomers to review a variety of cosmic mysteries, counting the actual nature of gravity itself. Initially exposed by an American graduate student by means of the National Science Foundation’s Green Bank Telescope, the pulsar, which is about 4,200 light-years from Earth, rotating approximately 366 times per second, was found to be in close by orbit with a white dwarf star and the couple is in orbit with additional, more distant white dwarf. The three-body arrangement is researchers’ best chance yet to learn a violation of a key idea in Albert Einstein’s theory of General Relativity: the strong equivalence principle, which says that that the outcome of gravity on a body does not rest on on the nature or inner structure of that body.
Stairs, with UBC’s Department of Physics and Astronomy, said “By doing very high-precision timing of the pulses coming from the pulsar, we can test for such a deviation from the strong equivalence principle at a sensitivity several orders of magnitude greater than ever before available. Finding a deviation from the strong equivalence principle would indicate a breakdown of General Relativity and would point us toward a new, revised theory of gravity.”
Scott Ransom of the National Radio Astronomy Observatory (NRAO), who directed the work, said “This is the first millisecond pulsar found in such a system, and we immediately recognized that it provides us a tremendous opportunity to study the effects and nature of gravity. This triple system gives us a natural cosmic laboratory far better than anything found before for learning exactly how such three-body systems work and potentially for detecting problems with General Relativity that physicists expect to see under extreme conditions.”
When a huge star detonates as a supernova and its leftovers fall into a super dense neutron star, few of its mass is transformed into gravitational binding energy that grips the dense star together. The strong equivalence principle states that this binding energy will still respond gravitationally as if it were mass. Nearly all replacements to General Relativity grip that it will not. In the strong equivalence principle, the gravitational result of the external white dwarf would be equal for both the internal white dwarf and the neutron star. If the strong equivalence principle is invalid beneath the conditions in this system, the outer star’s gravitational effect on the internal white dwarf and the neutron star would be to some extent different and the high-precision pulsar timing interpretations could simply display that. Anne Archibald of the Netherlands Institute for Radio Astronomy and one of the co-authors of the work said “We have made some of the most accurate measurements of masses in astrophysics. Some of our measurements of the relative positions of the stars in the system are accurate to hundreds of meters.” Archibald led the effort to use the measurements to build a computer simulation of the system that can predict its motions.
The NRAO’s Scott Ransom adds: “This is a fascinating system in many ways, including what must have been a completely crazy formation history, and we have much work to do to fully understand it.”
The worldwide group, which contains UBC astronomer Ingrid Stairs, reports their results in the journal Nature. The researchers’ observational program used the National Science Foundation’s Green Bank Telescope, the Arecibo radio telescope in Puerto Rico, and the Westerbork Synthesis Radio Telescope in the Netherlands. They also considered the system by means of data from the Sloan Digital Sky Survey, the GALEX satellite, the WIYN telescope on Kitt Peak, Arizona, and the Spitzer Space Telescope.
