The CARMENES search for exoplanets around M dwarfs : Understanding the wavelength dependence of radial velocity measurements
S. V. Jeffers, J. R. Barnes, P. Schöfer +22
Context. Current exoplanet surveys are focused on detecting small exoplanets orbiting in the liquid-water habitable zones of their host stars. Despite the recent significant advanc…
CARMENES input catalogue of M dwarfs VIII. Kinematics in the solar neighbourhood
M. Cortés-Contreras, J. A. Caballero, D. Montes +15
Aims. Our goals are to characterise the kinematic properties and to identify young and old stars among the M dwarfs of the CARMENES input catalogue. Methods. We compiled the spectr…
The CARMENES search for exoplanets around M dwarfs. Behaviour of the Paschen lines during flares and quiescence
B. Fuhrmeister, S. Czesla, J. H. M. M. Schmitt +17
The hydrogen Paschen lines are known activity indicators, but studies of them in M~dwarfs during quiescence are as rare as their reports in flare studies. This situation is mostly…
The CARMENES search for exoplanets around M dwarfs. Guaranteed time observations Data Release 1 (2016-2020)
I. Ribas, A. Reiners, M. Zechmeister +102
The CARMENES instrument was conceived to deliver high-accuracy radial velocity (RV) measurements with long-term stability to search for temperate rocky planets around a sample of n…
The CARMENES search for exoplanets around M dwarfs. Line-by-line sensitivity to activity in M dwarfs
M. Lafarga, I. Ribas, M. Zechmeister +17
Radial velocities (RVs) measured from high-resolution stellar spectra are routinely used to detect and characterise orbiting exoplanet companions. The different lines present in st…
The CARMENES search for exoplanets around M dwarfs, Wolf 1069 b: Earth-mass planet in the habitable zone of a nearby, very low-mass star
D. Kossakowski, M. Kürster, T. Trifonov +47
We present the discovery of an Earth-mass planet () on a 15.6d orbit of a relatively nearby (9.6pc) and low-mass () M…
The CARMENES search for exoplanets around M dwarfs: Stable radial-velocity variations at the rotation period of AD~Leonis -- A test case study of current limitations to treating stellar activity
D. Kossakowski, M. Kürster, Th. Henning +34
Context: A challenge with radial-velocity (RV) data is disentangling the origin of signals either due to a planetary companion or to stellar activity. In fact, the existence of a p…
The CARMENES search for exoplanets around M dwarfs. Rotational variation in activity indicators of Ross 318, YZ CMi, TYC 3529-1437-1, and EV Lac
P. Schöfer, S. V. Jeffers, A. Reiners +22
The CARMENES instrument is searching for periodic radial-velocity (RV) variations of M dwarfs, which are induced by orbiting planets. However, there are other potential sources of…
A young spectroscopic binary in a quintuple system part of the Local Association
Carlos Cardona Guillén, Nicolas Lodieu, Víctor J. S. Béjar +9
Double-lined spectroscopic binaries (SB2) allow us to determine a lower limit of the masses of their components directly to test stellar models. In this work, our aim is to derive…
The CARMENES search for exoplanets around M dwarfs: Spectroscopic orbits of nine M-dwarf multiple systems, including two triples, two brown dwarf candidates, and one close M-dwarf-white dwarf binary
D. Baroch, J. C. Morales, I. Ribas +33
M dwarfs are ideal targets for the search of Earth-size planets in the habitable zone using the radial velocity method, attracting the attention of many ongoing surveys. As a by-pr…
The CARMENES search for exoplanets around M dwarfs. Two terrestrial planets orbiting G 264-012 and one terrestrial planet orbiting Gl 393
P. J. Amado, F. F. Bauer, C. Rodríguez López +51
We report the discovery of two planetary systems, namely G 264-012, an M4.0 dwarf with two terrestrial planets ( M and $M_{\rm c…
