Such variability may be caused by the presence of a close main-sequence dwarf companion star with a mass below 0.1 solar masses. Based on the results, the authors of the paper noted that the dust ...

In the new study, published April 4 in the journal Nature Astronomy, researchers revealed that WDJ181058.67+311940.94, a white dwarf binary star system located just 150 light-years from Earth, is ...

Abstract: We use 1-m-class telescopes and the Transiting Exoplanet Survey Satellite (TESS) to explore the photometric variability of all known rapidly rotating (vsin i ≳ 30 km s −1) ultra-cool (≥M7) ...
