The MOPYS project: A survey of 70 planets in search of extended He I and H atmospheres. No evidence of enhanced evaporation in young planets
J. Orell-Miquel, F. Murgas, E. Pallé +30
During the first Gyr of their life, exoplanet atmospheres suffer from different atmospheric escape phenomena that can strongly affect the shape and morphology of the exoplanet itse…
CARMENES input catalog of M dwarfs VI. A time-resolved Ca II H&K catalog from archival data
V. Perdelwitz, M. Mittag, L. Tal-Or +15
Radial-velocity (RV) jitter caused by stellar magnetic activity is an important factor in state-of-the-art exoplanet discovery surveys such as CARMENES. Stellar rotation, along wit…
A super-Earth on a close-in orbit around the M1V star GJ 740. A HADES and CARMENES collaboration
B. Toledo-Padrón, A. Suárez Mascareño, J. I. González Hernández +23
M-dwarfs have proven to be ideal targets for planetary radial velocity (RV) searches due to their higher planet-star mass contrast. The HADES and CARMENES programs aim to carry out…
The CARMENES search for exoplanets around M dwarfs. Three temperate to warm super-Earths
S. Stock, E. Nagel, J. Kemmer +37
We announce the discovery of two planets orbiting the M dwarfs GJ 251 ( M) and HD 238090 ( M) based on CARMENES radial velocity (RV) d…
The CARMENES search for exoplanets around M dwarfs: Rubidium abundances in nearby cool stars
C. Abia, H. M. Tabernero, S. A. Korotin +25
In this study, abundances of the neutron-capture elements Rb, Sr, and Zr are derived, for the first time, in a sample of nearby M dwarfs. We focus on stars in the metallicity range…
The CARMENES search for exoplanets around M dwarfs -- A deep learning approach to determine fundamental parameters of target stars
V. M. Passegger, A. Bello-García, J. Ordieres-Meré +26
Existing and upcoming instrumentation is collecting large amounts of astrophysical data, which require efficient and fast analysis techniques. We present a deep neural network arch…
CARMENES input catalogue of M dwarfs V. Luminosities, colours, and spectral energy distributions
C. Cifuentes, J. A. Caballero, M. Cortes-Contreras +15
The relevance of M dwarfs in the search for potentially habitable Earth-sized planets has grown significantly in the last years. In our on-going effort to comprehensively and accur…
The CARMENES search for exoplanets around M dwarfs: Convective shift and starspot constraints from chromatic radial velocities
D. Baroch, J. C. Morales, I. Ribas +26
Context. Variability caused by stellar activity represents a challenge to the discovery and characterization of terrestrial exoplanets and complicates the interpretation of atmosph…
The CARMENES search for exoplanets around M dwarfs. Measuring precise radial velocities in the near infrared: the example of the super-Earth CD Cet b
F. F. Bauer, M. Zechmeister, A. Kaminski +26
The high-resolution, dual channel, visible and near-infrared spectrograph CARMENES offers exciting opportunities for stellar and exoplanetary research on M dwarfs. In this work we…
The CARMENES search for exoplanets around M dwarfs. Dynamical characterization of the multiple planet system GJ 1148 and prospects of habitable exomoons around GJ 1148 b
T. Trifonov, M. H. Lee, M. Kürster +29
Context. GJ 1148 is an M-dwarf star hosting a planetary system composed of two Saturn-mass planets in eccentric orbits with periods of 41.38 and 532.02 days. Aims. We reanalyze the…
An Aladin-based search for proper-motion companions to young stars in the Local Association, Tucana-Horologium and beta Pictoris
F. J. Alonso-Floriano, J. A. Caballero, D. Montes
We have used the Aladin sky atlas of the Virtual Observatory to look for new common proper-motion pairs in three young stellar kinematic groups: Local Association (~10-120 Ma), Tuc…
