The CARMENES search for exoplanets around M dwarfs - HD 147379b: A nearby Neptune in the temperate zone of an early-M dwarf
A. Reiners, I. Ribas, M. Zechmeister +169
We report on the first star discovered to host a planet detected by radial velocity (RV) observations obtained within the CARMENES survey for exoplanets around M dwarfs. HD 147379…
The CARMENES search for exoplanets around M dwarfs: High-resolution optical and near-infrared spectroscopy of 324 survey stars
A. Reiners, M. Zechmeister, J. A. Caballero +170
The CARMENES radial velocity (RV) survey is observing 324 M dwarfs to search for any orbiting planets. In this paper, we present the survey sample by publishing one CARMENES spectr…
Detection of sodium in the atmosphere of WASP-69b
N. Casasayas-Barris, E. Palle, G. Nowak +3
Transit spectroscopy is one of the most commonly used methods to characterize exoplanets atmospheres. From the ground, these observations are very challenging due to the terrestria…
The CARMENES search for exoplanets around M dwarfs. First visual-channel radial-velocity measurements and orbital parameter updates of seven M-dwarf planetary systems
T. Trifonov, M. Kürster, M. Zechmeister +166
Context: The main goal of the CARMENES survey is to find Earth-mass planets around nearby M-dwarf stars. Seven M-dwarfs included in the CARMENES sample had been observed before wit…
The GTC exoplanet transit spectroscopy survey VIII. Flat transmission spectrum for the warm gas giant WASP-80
Hannu Parviainen, Enric Palle, Guo Chen +7
We set out to study the atmosphere of WASP-80b, a warm inflated gas giant with an equilibrium temperature of 800~K, using ground-based transmission spectroscopy covering the…
The GTC exoplanet transit spectroscopy survey. VII. An optical transmission spectrum of WASP-48b
F. Murgas, E. Pallé, H. Parviainen +5
We obtained long-slit optical spectroscopy of one transit of WASP-48b with the Optical System for Imaging and low-Intermediate-Resolution Integrated Spectroscopy (OSIRIS) spectrogr…
