Detonating white dwarfs as supernovae
New York NY (SPX) Oct 12, 2016
A new mathematical model created by astrophysicists at the American Museum of Natural History details a way that dead stars called white dwarfs could detonate, producing a type of explosion that is instrumental to measuring the extreme distances in our universe. The mechanism, described in the Monthly Notices of the Royal Astronomical Society, could improve our understanding of how Type Ia supernovae form. "Type Ia supernovae are extremely important objects in physics, best known for their role in ... read more

Using oxygen as a tracer of galactic evolution A new study led by University of California, Riverside astronomers casts light on how young, hot stars ionize oxygen in the early universe and the effects on the evolution of galaxies through time. ... more		Stellar ages in seconds Living for billions and billions of years, it is no simple task to figure out how old a star is. Fortunately, despite appearances, earthquake-like pulsations cause stars like our Sun to vibrate, imp ... more		Discovery of an extragalactic hot molecular core Astronomers have discovered a 'hot molecular core,' a cocoon of molecules surrounding a newborn massive star, for the first time outside our Galaxy. The discovery, which marks the first important st ... more
				Discovery: A new form of light Glow-in-the-dark stickers, weird deep-sea fish, LED lightbulbs - all have forms of luminescence. In other words, instead of just reflecting light, they make their own. Now a team of scientists from ... more		Observing the birth of quasiparticles in real time The concept of quasiparticles is a powerful tool to describe processes in many-body quantum systems, such as solid-state materials. For example, when an electron moves through a solid, it generates ... more

Kepler Gets the 'Big Picture' of Comet 67P On Sept. 30, the European Space Agency concluded its Rosetta mission and the study of comet 67P/Churyumov-Gerasimenko.
