Ground-based detection of an extended helium atmosphere in the Saturn-mass exoplanet WASP-69b
Lisa Nortmann, Enric Pallé, Michael Salz +25
Hot gas giant exoplanets can lose part of their atmosphere due to strong stellar irradiation, affecting their physical and chemical evolution. Studies of atmospheric escape from ex…
Detection of He I Å absorption on HD 189733 b with CARMENES high-resolution transmission spectroscopy
M. Salz, S. Czesla, P. C. Schneider +35
We present three transit observations of HD 189733 b obtained with the high-resolution spectrograph CARMENES at Calar Alto. A strong absorption signal is detected in the near-infra…
Stellar activity analysis of Barnard's Star: Very slow rotation and evidence for long-term activity cycle
B. Toledo-Padrón, J. I. González Hernández, C. Rodríguez-López +58
The search for Earth-like planets around late-type stars using ultra-stable spectrographs requires a very precise characterization of the stellar activity and the magnetic cycle of…
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…
Contemporaneous broad-band photometry and H observations of T Tauri stars
A. Frasca, D. Montes, J. M. Alcalá +2
The study of contemporaneous variations of the continuum flux and emission lines is of great importance to understand the different astrophysical processes at work in T Tauri stars…
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…
