K2-141 b: A 5-M super-Earth transiting a K7 V star every 6.7 hours
O. Barragán, D. Gandolfi, F. Dai +32
We report on the discovery of K2-141 b (EPIC 246393474 b), an ultra-short-period super-Earth on a 6.7-hour orbit transiting an active K7 V star based on data from K2 campaign 12. W…
The discovery and mass measurement of a new ultra-short-period planet: EPIC~228732031b
Fei Dai, Joshua N. Winn, Davide Gandolfi +51
We report the discovery of a new ultra-short-period planet and summarize the properties of all such planets for which the mass and radius have been measured. The new planet, EPIC~2…
K2-137 b: an Earth-sized planet in a 4.3-hour orbit around an M-dwarf
A. M. S. Smith, J. Cabrera, Sz. Csizmadia +34
We report the discovery from K2 of a transiting terrestrial planet in an ultra-short-period orbit around an M3-dwarf. K2-137 b completes an orbit in only 4.3 hours, the second-shor…
The transiting multi-planet system HD3167: a 5.7 MEarth Super-Earth and a 8.3 MEarth mini-Neptune
Davide Gandolfi, Oscar Barragán, Artie P. Hatzes +42
HD3167 is a bright (V=8.9 mag) K0V star observed by the NASA's K2 space mission during its Campaign 8. It has been recently found to host two small transiting planets, namely, HD31…
K2-106, a system containing a metal-rich planet and a planet of lower density
E. W. Guenther, O. Barragan, F. Dai +42
Planets in the mass range from 2 to 15 MEarth are very diverse. Some of them have low densities, while others are very dense. By measuring the masses and radii, the mean densities,…
