Abstract

We present the discovery of K2-140b, a P = 6.57 d Jupiter-mass (M_P = 1.019 ± 0.070M_Jup) planet transiting a V = 12.5 (G5-spectral type) star in an eccentric orbit (e = 0.120_-0.046 ^+0.056) detected using a combination of K2 photometry and ground-based observations. With a radius of 1.095 ± 0.018 R_Jup, the planet has a bulk density of 0.726 ± 0.062 _ρJup. The host star has a [Fe/H] of 0.12 ± 0.045, and from the K2 light curve, we find a rotation period for the star of 16.3 ± 0.1 d. This discovery is the 9th hot Jupiter from K2 and highlights K2's ability to detect transiting giant planets at periods slightly longer than traditional, ground-based surveys. This planet is slightly inflated, but much less than others with similar incident fluxes. These are of interest for investigating the inflation mechanism of hot Jupiters.
