Thermonuclear Supernova Ejects White Dwarf from Binary System | Astronomy – Sci-News.com
A white dwarf star called SDSS J124043.01+671034.68 (SDSS J1240+6710) is traveling at 900,000 km/h (559,234 mph) through our Milky Way Galaxy.
A white dwarf star called SDSSJ124043.01+671034.68 (SDSSJ1240+6710) is traveling at 900,000 km/h (559,234 mph) through our Milky Way Galaxy. It also has a particularly low mass for a white dwarf — only 40% the mass of our Sun — which would be consistent with the loss of mass from a partial supernova. According to new research, SDSS J1240+6710 was most likely a member of a binary system that survived a so-called thermonuclear supernova event, which sent it and its companion flying through the Mil…
