K2-24
K2-24 (also known as EPIC 203771098) is a metal-rich G3-type main sequence star larger and more massive than the sun, located away in the constellation Scorpius. Two confirmed transiting exoplanets are known to orbit this star. An attempt to detect stellar companions using adaptive optics imaging at the Keck telescope was negative however later observations using lucky imaging at the Danish 1.54 m telescope at La Silla Observatory detected a possible companion at 3.8 arcseconds distance from K2-24. This candidate companion being over 8 magnitudes fainter than K2-24 and with a color temperature of , is inconsistent with a bound main sequence companion.
