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…
Phase-dependent study of near-infrared disk emission lines in LB-1
Jifeng Liu, Zheng Zheng, Roberto Soria +19
The mass, origin and evolutionary stage of the binary system LB-1 has been the subject of intense debate, following the claim that it hosts an 70 black hole, in st…
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…
Stellar activity analysis of Barnard's Star: Very slow rotation and evidence for long-term activity cycle
B. Toledo-Padrón, J. I. González Hernández, C. Rodríguez-López +58
The search for Earth-like planets around late-type stars using ultra-stable spectrographs requires a very precise characterization of the stellar activity and the magnetic cycle of…
The CARMENES search for exoplanets around M dwarfs: Radial-velocity variations of active stars in visual-channel spectra
L. Tal-Or, M. Zechmeister, A. Reiners +22
Previous simulations predicted the activity-induced radial-velocity (RV) variations of M dwarfs to range from cm/s to km/s, depending on various stellar and activit…
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…
