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…
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. Variability of the He I line at 10830 Å
B. Fuhrmeister, S. Czesla, L. Hildebrandt +23
The He I infrared (IR) triplet at 10830 Åis known as an activity indicator in solar-type stars and has become a primary diagnostic in exoplanetary transmission spectroscopy. He I l…
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…
