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…
Multiple water band detections in the CARMENES near-infrared transmission spectrum of HD 189733 b
F. J. Alonso-Floriano, A. Sánchez-López, I. A. G. Snellen +27
Aims: We explore the capabilities of CARMENES for characterizing hot-Jupiter atmospheres by targeting multiple water bands, in particular, those at 1.15 and 1.4 m. Hubble Space…
Prospects for detecting the astrometric signature of Barnard's Star b
Lev Tal-Or, Shay Zucker, Ignasi Ribas +2
A low-amplitude periodic signal in the radial velocity (RV) time series of Barnard's Star was recently attributed to a planetary companion with a minimum mass of 3.2 $M_\op…
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…
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: Nine new double-line spectroscopic binary stars
D. Baroch, J. C. Morales, I. Ribas +27
Context. The CARMENES spectrograph is surveying ~300 M dwarf stars in search for exoplanets. Among the target stars, spectroscopic binary systems have been discovered, which can be…
