KIC 10001893: A Compact Trio Around a Hot Subdwarf
KIC 10001893 is a star 5460 light-years away, and three planets have been found orbiting it. The star itself has a reported mass estimate of 0.47 solar masses and a reported radius estimate of 0.18 solar radii. Its reported temperature of 31000 K is hotter than the Sun's.
All three planets were discovered in 2014 by orbital brightness modulation, a method that detects a planet as it dims and brightens light from its star. KIC 10001893 b completes an orbit in 0.22 days. KIC 10001893 c completes an orbit in 0.325 days. KIC 10001893 d completes an orbit in 0.812 days. Among the listed planets, b has the shortest orbital period by reported estimates, c has the second-shortest, and d has the longest.
