A Jovian planet in an eccentric 11.5 day orbit around HD1397 discovered by TESS
L. D. Nielsen, F. Bouchy, O. Turner +36
The Transiting Exoplanet Survey Satellite TESS has begun a new age of exoplanet discoveries around bright host stars. We present the discovery of HD 1397b (TOI-120.01), a giant pla…
Transiting planet candidate from K2 with the longest period
H. A. C. Giles, H. P. Osborn, S. Blanco-Cuaresma +8
Context: We present the transit and follow-up of a single transit event from Campaign 14 of K2, EPIC248847494b, which has a duration of 54 hours and a 0.18% depth. Aims: Using phot…
An Earth-sized exoplanet with a Mercury-like composition
A. Santerne, B. Brugger, D. J. Armstrong +43
The Earth, Venus, Mars, and some extrasolar terrestrial planets have a mass and radius that is consistent with a mass fraction of about 30% metallic core and 70% silicate mantle. A…
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…
Validation and Initial Characterization of the Long Period Planet Kepler-1654 b
C. A. Beichman, H. A. C. Giles, R. Akeson +12
Fewer than 20 transiting Kepler planets have periods longer than one year. Our early search of the Kepler light curves revealed one such system, Kepler-1654 b (originally KIC~84106…
