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…
K2-139 b: a low-mass warm Jupiter on a 29-day orbit transiting an active K0 V star
O. Barragán, D. Gandolfi, A. M. S. Smith +27
We announce the discovery of K2-139 b (EPIC 218916923 b), a transiting warm-Jupiter (=54725 K) on a 29-day orbit around an active (log =…
K2-60b and epic 216468514b. A sub-jovian and a jovian planet from the k2 mission
Philipp Eigmüller, Davide Gandolfi, Carina M. Persson +20
We report the characterization and independant detection of K2-60b, as well as the detection and characterization of EPIC 216468514b, two transiting hot gaseous planets from the K2…
Mass determination of K2-19b and K2-19c from radial velocities and transit timing variations
D. Nespral, D. Gandolfi, H. J. Deeg +21
We present FIES@NOT, HARPS-N@TNG, and [email protected] radial velocity follow-up observations of K2-19, a compact planetary system hosting three planets, of which the two larger ones…
Two Hot Jupiters from K2 Campaign 4
Marshall C. Johnson, Davide Gandolfi, Malcolm Fridlund +20
We confirm the planetary nature of two transiting hot Jupiters discovered by the Kepler spacecraft's K2 extended mission in its Campaign 4, using precise radial velocity measuremen…
K2-31b, a grazing transiting hot Jupiter on an 1.26-day orbit around a bright G7V star
S. Grziwa, D. Gandolfi, Sz. Csizmadia +25
We report the discovery of K2-31b, the first confirmed transiting hot Jupiter detected by the K2 space mission. We combined K2 photometry with FastCam lucky imaging and FIES and HA…
