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 ...

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 ...

Photo Caption: An artist’s conception of EF Eri during a time when there is mass accretion from the donor star to the white dwarf. The region where the thin gas stream breaks up into many filaments is ...

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 ...

Astronomers have just discovered a new Earth-sized exoplanet around SPECULOOS-3, an 'ultracool dwarf' star as small as Jupiter, twice as cold as our Sun, and located 55 light-years from Earth. After ...

Exoplanet science and the search for life beyond Earth continue to advance at break-neck speeds, with the number of confirmed exoplanets by NASA rapidly approaching 6,300, with 223 of those exoplanets ...

The six known DAQ type white dwarfs exhibit log (C/H) > –0.5 and appear in optical spectra. WD 0525+526 shows how many merger remnants may hide beneath pure hydrogen layers, detectable only in ...

A 2020 microlensing event was caused by a planetary system with an Earth-like planet and brown dwarf. The star type was uncertain. The team has determined that the star is a white dwarf, a system ...

NASA’s Transiting Exoplanet Survey Satellite has identified TOI-4616 b, an Earth-sized planet transiting a cool M4 dwarf star in the solar neighborhood. The discovery, detailed in a new preprint, adds ...
