Because the star is evolving up the sub-giant branch, K2 - 66b receives a high level... ▽ More We report precise mass and density measurements of two extremely hot sub-Neptune-size planets from the K2 mission using radial velocities, K2 photometry, and adaptive optics imaging.
The planets are mostly smaller than Neptune (21/26 planets) as in the Kepler mission and all have short periods ($ P < 50 $ d) due to the duration of the K2 photometry.
Here we combine K2 photometry with spectroscopy, adaptive optics imaging, and archival survey images to analyze two small planets orbiting the nearby, field age, M dwarfs K2 - 26 (EPIC 202083828) and K2 - 9.
We obtained follow - up optical spectra of 105/141 candidate host stars and 8/16 eclipsing binaries to improve stellar properties and to identify spectroscop... ▽ More We present 151 planet candidates orbiting 141 stars from K2 campaigns 5 - 8 (C5 - C8), identified through a systematic search of K2 photometry.
