The CARMENES search for exoplanets around M dwarfs: Not-so-fine hyperfine-split vanadium lines in cool star spectra
Yutong Shan, Ansgar Reiners, Damian Fabbian +24
(Abridged) We characterize a series of neutral vanadium atomic absorption lines in the 800--910nm wavelength region of high signal-to-noise, high-resolution, telluric-corrected M-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: Different roads to radii and masses of the target stars
Andreas Schweitzer, V. M. Passegger, C. Cifuentes +28
We determine the radii and masses of 293 nearby, bright M dwarfs of the CARMENES survey. This is the first time that such a large and homogeneous high-resolution (R>80 000) spectro…
