TESS exoplanet candidates validated with HARPS archival data. A massive Neptune around GJ143 and two Neptunes around HD23472
Trifon Trifonov, Jan Rybizki, Martin Kürster
We aim at the discovery of new planetary systems by exploiting the transit light curve results from TESS orbital observatory's Sector 1 and 2 observations and validating them with…
A candidate super-Earth planet orbiting near the snow line of Barnard's star
I. Ribas, M. Tuomi, A. Reiners +60
At a distance of 1.8 parsecs, Barnard's star (Gl 699) is a red dwarf with the largest apparent motion of any known stellar object. It is the closest single star to the Sun, second…
The CARMENES search for exoplanets around M dwarfs: The warm super-Earths in twin orbits around the mid-type M dwarfs Ross 1020 (GJ 3779) and LP 819-052 (GJ 1265)
R. Luque, G. Nowak, E. Pallé +27
We announce the discovery of two planetary companions orbiting around the low mass stars Ross 1020 (GJ 3779, M4.0V) and LP 819-052 (GJ 1265, M4.5V). The discovery is based on the a…
New HARPS and FEROS observations of GJ1046
Trifon Trifonov, Martin Kürster, Sabine Reffert +16
In this paper we present new precise Doppler data of GJ1046 taken between November 2005 and July 2018 with the HARPS and the FEROS high-resolution spectographs. In addition, we pro…
HD 202772A B: A Transiting Hot Jupiter Around A Bright, Mildly Evolved Star In A Visual Binary Discovered By Tess
Songhu Wang, Matias Jones, Avi Shporer +52
We report the first confirmation of a hot Jupiter discovered by the Transiting Exoplanet Survey Satellite (TESS) mission: HD 202772A b. The transit signal was detected in the data…
Correcting HIRES radial velocities for small systematic errors
Lev Tal-Or, Trifon Trifonov, Shay Zucker +2
The HIRES spectrograph, mounted on the -m Keck-I telescope, belongs to a small group of radial-velocity (RV) instruments that produce stellar RVs with long-term precision down…
The CARMENES search for exoplanets around M dwarfs. A Neptune-mass planet traversing the habitable zone around HD 180617
A. Kaminski, T. Trifonov, J. A. Caballero +37
Despite their activity, low-mass stars are of particular importance for the search of exoplanets by the means of Doppler spectroscopy, as planets with lower masses become detectabl…
K2-260 b: a hot Jupiter transiting an F star, and K2-261 b: a warm Saturn around a bright G star
M. C. Johnson, F. Dai, A. B. Justesen +45
We present the discovery and confirmation of two new transiting giant planets from the Kepler extended mission K2. K2-260 b is a hot Jupiter transiting a F6V star in K2 Fi…
HD 89345: a bright oscillating star hosting a transiting warm Saturn-sized planet observed by K2
V. Van Eylen, F. Dai, S. Mathur +40
We report the discovery and characterization of HD 89345b (K2-234b; EPIC 248777106b), a Saturn-sized planet orbiting a slightly evolved star. HD 89345 is a bright star ( m…
The CARMENES search for exoplanets around M dwarfs: A low-mass planet in the temperate zone of the nearby K2-18
Paula Sarkis, Thomas Henning, Martin Kürster +22
K2-18 is a nearby M2.5 dwarf, located at 34 pc and hosting a transiting planet which was first discovered by the {\it K2} mission and later confirmed with {\it Spitzer Space Telesc…
Dynamical analysis of the circumprimary planet in the eccentric binary system HD59686
Trifon Trifonov, Man Hoi Lee, Sabine Reffert +1
We present a detailed orbital and stability analysis of the HD~59686 binary-star planet system. HD~59686 is a single-lined moderately close (AU) eccentric ($e_{B} =…
