Description

We have identified three K2 transiting star–planet systems, K2-51 (EPIC 202900527), K2-67 (EPIC 206155547), and K2-76 (EPIC 206432863), as stellar binaries with low-mass stellar secondaries. The three systems were statistically validated as transiting planets, and through measuring their orbits by radial velocity (RV) monitoring we have derived the companion masses to be -0.1459+0.0032 0.0029 ☉ M (EPIC 202900527 B), -0.1612+0.0067 0.0072 ☉ M (EPIC206155547B), and 0.0942±0.0019 ☉ M (EPIC...[Show more]
