A pair of physicists hired to help lead particle and nuclear physics research in the new doctorate program at South Dakota School of Mines & Technology hold the promise of bringing the long-awaited
The neutrino plays a crucial role in nuclear processes such as fusion. But because of its small mass and neutral charge, it is very difficult to measure and study and as a result has been a source of frustration to physicists and astronomers.
The so-called 'I Love Q' equation that relates to neutron stars may offer surprising insights into the nature of the universe.
Researchers recently studied a distant white dwarf star to measure the strength of the electromagnetic force, one of the four fundamental forces that shape the universe as we know it. They hoped to determine whether the laws of physics were constant throughout the universe.
Researchers from the Max Planck Institute for Astrophysics have, for the first time, created three-dimensional computer models in order to study the formation of neutron stars at the center of collapsing stars, officials from the German research center announced earlier this week.
A group of astronomers have discovered pulsations from the crystallized remnant of a burnt-out white dwarf star.
An international team of researchers has created a map of the Universe near the Milky Way that better represents the physical dimensions of space. To accomplish this, the team created a video that allows for the perception of depth by rotating, zooming, and panning across the map space.
New research is building upon the notion that dark matter may be Majorana particles, and suggests that perhaps dark matter can interact electromagnetically after all – meaning that dark matter may not be ‘dark’ after all.
Astronomers using the Karoo Array Telescope (KAT-7) in South Africa have revealed giant outbursts from X-ray binary star system Circinus X-1. The team watched as the double star system fired off energetic matter from its core into the surrounding system in extensive, compact jets that flared brightly.
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...
