HD219666b: A hot-Neptune from TESS Sector 1
M. Esposito, D. J. Armstrong, D. Gandolfi +73
We report on the confirmation and mass determination of a transiting planet orbiting the old and inactive G7 dwarf star HD219666 (Mstar = 0.92 +/- 0.03 MSun, Rstar = 1.03 +/- 0.03…
K2-140b and K2-180b - Characterization of a hot Jupiter and a mini-Neptune from the K2 mission
J. Korth, Sz. Csizmadia, D. Gandolfi +40
We report the independent discovery and characterization of two K2 planets: K2-180b, a mini-Neptune-size planet in an 8.9-day orbit transiting a V = 12.6 mag, metal-poor ([Fe/H] =$…
TESS's first planet: a super-Earth transiting the naked-eye star Mensae
D. Gandolfi, O. Barragan, J. Livingston +29
We report on the confirmation and mass determination of Pi Men c, the first transiting planet discovered by NASA's TESS space mission. Pi Men is a naked-eye (V=5.65 mag), quiet G0…
K2-264: A transiting multi-planet system in the Praesepe open cluster
John H. Livingston, Fei Dai, Teruyuki Hirano +31
Planet host stars with well-constrained ages provide a rare window to the time domain of planet formation and evolution. The NASA K2 mission has enabled the discovery of the vast m…
A 4.6-year period brown-dwarf companion interacting with the hot-Jupiter CoRoT-20 b
J. Rey, F. Bouchy, M. Stalport +18
We report the discovery of an additional substellar companion in the CoRoT-20 system based on six years of HARPS and SOPHIE radial velocity follow-up. CoRoT-20 c has a minimum mass…
44 Validated Planets from K2 Campaign 10
John H. Livingston, Michael Endl, Fei Dai +31
We present 44 validated planets from the 10 observing campaign of the NASA mission, as well as high resolution spectroscopy and speckle imaging follow-up observa…
