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…
EPIC 219388192 b - an inhabitant of the brown dwarf desert in the Ruprecht 147 open cluster
Grzegorz Nowak, Enric Palle, Davide Gandolfi +32
We report the discovery of EPIC 219388192 b, a transiting brown dwarf in a 5.3-day orbit around a member star of Ruprecht-147, the oldest nearby open cluster association, which was…
K2-99: a subgiant hosting a transiting warm Jupiter in an eccentric orbit and a long-period companion
A. M. S. Smith, D. Gandolfi, O. Barragán +30
We report the discovery from K2 of a transiting planet in an 18.25-d, eccentric (0.19 0.04) orbit around K2-99, an 11th magnitude subgiant in Virgo. We confirm the planetary n…
K2-98 b: A 32-M Neptune-sized planet in a 10-day orbit transiting an F8 star
Oscar Barragán, Sascha Grziwa, Davide Gandolfi +21
We report the discovery of K2-98 b (EPIC 211391664 b), a transiting Neptune-sized planet monitored by the K2 mission during its campaign 5. We combine the K2 time-series data with…
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…
An M dwarf Companion to an F-type Star in a young main-sequence binary
Ph. Eigmüller, J. Eislöffel, Sz. Csizmadia +9
Only a few well characterized very low-mass M dwarfs are known today. Our understanding of M dwarfs is vital as these are the most common stars in our solar neighborhood. We aim to…
