AUSTIN, Texas — University of Texas at Austin astronomers Michael H. Montgomery and Kurtis A. Williams, along with graduate student Steven DeGennaro, have predicted and confirmed the existence of a ...
Four dead stars have been hiding in Earth’s cosmic backyard, unnoticed for decades despite lying within just 65 light-years ...
Scientists have identified new clues that could help astronomers spot one of the most famous hypothetical alien ...
Astronomers have discovered the first pairs of white dwarf and main sequence stars -- 'dead' remnants and 'living' stars -- in young star clusters. This breakthrough offers new insights on an extreme ...
Using the Special Astrophysical Observatory (SAO), Russian astronomers have carried out spectroscopic and photometric observations of a cataclysmic variable designated Gaia 19cwm, finding that it is a ...
Binary star systems are not rare. Neither are systems where one star is a remnant like a white dwarf or neutron star, and its companion is on the main sequence. In those systems, the dense remnant can ...
Somewhere between 50 and 200 million years ago, in three stellar nurseries not far from our corner of the Milky Way, at least six small red dwarf stars did something violent: they swallowed rocky ...
A type Ia supernova occurs when a white dwarf — the cooling remnant of an aging star — draws hydrogen from a companion sun. When the dwarf reaches 1.4 times the mass of the Sun, the star spontaneously ...
How many exoplanets orbit M-dwarfs stars, the latter of which is the most common type of star in the galaxy? This is what a recent study published in The Astronomical Journal hopes to address as a ...
