"China-Led Team Discovers Ghostly Lone Companion of Smallest Star in Exotic Binary System"
TL;DR
Astronomers have discovered an extraordinary binary system, TMTS J0526, containing a small white dwarf star and a hot subdwarf star with an incredibly short orbital period of around 20 minutes. This system, located 2,760 light-years from Earth, provides evidence for the formation of tiny hot subdwarfs through the ejection of common envelopes. The discovery sheds light on the birth of such small subdwarf stars and could help explain their origins in the universe.
