K2-263b: A 50-day period sub-Neptune with a mass measurement using HARPS-N
A. Mortier, A. S. Bonomo, V. M. Rajpaul +32
This paper reports on the validation and mass measurement of K2-263b, a sub-Neptune orbiting a quiet G9V star. Using K2 data from campaigns C5 and C16, we find this planet to have…
A second terrestrial planet orbiting the nearby M dwarf LHS 1140
Kristo Ment, Jason A. Dittmann, Nicola Astudillo-Defru +27
LHS 1140 is a nearby mid-M dwarf known to host a temperate rocky super-Earth (LHS 1140 b) on a 24.737-day orbit. Based on photometric observations by MEarth and Spitzer as well as…
Planet Size Distribution from the Kepler Mission and its Implications for Planet Formation
Li Zeng, Stein B. Jacobsen, Eugenia Hyung +8
The size distribution of exoplanets is a bimodal division into two groups: Rocky planet (<2 Earth radii) and water-rich planet (>2 Earth radii) with or without gaseous envelope.
An accurate mass determination for Kepler-1655b, a moderately-irradiated world with a significant volatile envelope
R. D. Haywood, A. Vanderburg, A. Mortier +32
We present the confirmation of a small, moderately-irradiated (F = 155 +/- 7 Fearth) Neptune with a substantial gas envelope in a P=11.8728787+/-0.0000085-day orbit about a quiet,…
Understanding Stellar Contamination in Exoplanet Transmission Spectra as an Essential Step in Small Planet Characterization
Dániel Apai, Benjamin V. Rackham, Mark S. Giampapa +18
Transmission spectroscopy during planetary transits is expected to be a major source of information on the atmospheres of small (approximately Earth-sized) exoplanets in the next t…
Eyes on K2-3: A system of three likely sub-Neptunes characterized with HARPS-N and HARPS
M. Damasso, A. S. Bonomo, N. Astudillo-Defru +67
M-dwarf stars are promising targets for identifying and characterizing potentially habitable planets. K2-3 is a nearby (45 pc), early-type M dwarf hosting three small transiting pl…
An ultra-short period rocky super-Earth with a secondary eclipse and a Neptune-like companion around K2-141
Luca Malavolta, Andrew W. Mayo, Tom Louden +44
Ultra-short period (USP) planets are a class of low mass planets with periods shorter than one day. Their origin is still unknown, with photo-evaporation of mini-Neptunes and in-si…
