Dark matter, the mysterious substance that comprises more than 85 percent of the universe, is unlikely to be made of primordial black holes due to the existence of neutron stars.
The black hole in question is orbiting an object known as a Be-type star, which is unusual because of its incredibly high rate of rotation.
The discovery of a superdense neutron star in a stellar triple system has made it possible for researchers to collect the best measurements to date of the complex gravitational interactions present in these types of systems, according to a new Nature study.
Astronomers may have found two systems that may ultimately evolve into a rare Am CVn binary system.
Albeit with much controversy, physicists are using ancient lead ingots from sunken ships in the study of dark matter in neutrinos. Archaeologists have gone on the offensive, expressing concerns over the destruction of underwater cultural heritage.
New research appearing in the latest edition of the journal Nature is casting doubts on currently accepted theories has to how the surface of a neutron star heats itself up.
They are the coldest objects in the Universe and are so fragile that even a single photon can heat and destroy them.
Just three months into its operation, the Large Underground Xenon experiment is already the most sensitive dark matter detector in the world.
MIT physicists have proposed a new experiment to look for the elusive dark matter particle known as the 'A Prime' particle.
WIMP -- In astronomy, WIMPs, or weakly interacting massive particles, figure into one explanation of the dark matter problem. The particles are called "weakly interacting" because they seem not to have much interaction with normal matter (electrons, protons, and neutrons) other than gravitational attraction (thus "massive"). Assuming that there are Weakly Interacting Massive Particles, these particles would then fall out of equilibrium with the universe when they are non-relativistic....
White Dwarf -- A white dwarf is a a star supported by electron degeneracy. A star like our Sun will become a white dwarf when it has exhausted its nuclear fuel. Near the end of its nuclear burning stage, such a star goes through a red giant phase and then expels most of its outer material (creating a planetary nebula) until only the hot (T > 100,000 K) core remains, which then settles down to become a young white dwarf. A typical white dwarf is half as massive as the Sun, yet only...
Supernova -- A supernova is a star that increases its brightness drastically within a matter of days, making it appear as if a "new" star was born (hence "nova"). The "super" prefix distinguishes it from a mere nova, which also involves a star increasing in brightness, though to a lesser extent and through a much different mechanism. Astronomers have classified supernovae in several classes, according to the lines of different elements that appear in their spectra. The first element...
Strange Matter -- Strange matter (also known as quark matter) is an ultra-dense phase of matter that is theorized to form inside particularly massive neutron stars (which are then known as "strange stars" or "quark stars"). It's theorized that when neutronium is put under sufficient pressure due to the gravitation of a large neutron star, the individual neutrons break down and their constituent quarks form strange matter. Strange matter is composed of strange quarks bound to each...
Massive Compact Halo Object (MACHO) -- Massive compact halo objects, or MACHOs, are a type of astronomical body proposed as one possible explanation for the presence of dark matter in galactic halos. A MACHO is a small chunk of normal baryonic matter, far smaller than a star, which drifts through interstellar space unassociated with any solar system. Since MACHOs would not emit any light of their own, they would be very hard to detect. Recent work has suggested that MACHOs are not...
