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…
The CARMENES search for exoplanets around M dwarfs. Cluster analysis of signals from spectral activity indicators to search for shared periods
J. Kemmer, M. Lafarga, B. Fuhrmeister +17
A multitude of spectral activity indicators are routinely computed nowadays from the spectra generated as part of planet-hunting radial velocity surveys. Searching for shared perio…
The CARMENES search for exoplanets around M dwarfs. Occurrence rates of Earth-like planets around very low-mass stars
A. Kaminski, S. Sabotta, J. Kemmer +24
Aims: Previous estimates of planet occurrence rates in the CARMENES survey indicated increased numbers of planets on short orbits for M dwarfs with masses below 0.34\,M. He…
The CARMENES search for exoplanets around M dwarfs. The impact of rotation and magnetic fields on the radial velocity jitter in cool stars
H. L. Ruh, M. Zechmeister, A. Reiners +19
Radial velocity (RV) jitter represents an intrinsic limitation on the precision of Doppler searches for exoplanets that can originate from both instrumental and astrophysical sourc…
The CARMENES search for exoplanets around M dwarfs: Magnesium and silicon abundances of K7-M5.5 stars
H. M. Tabernero, Y. Shan, J. A. Caballero +13
We present the abundances of magnesium (Mg) and silicon (Si) for 314 dwarf stars with spectral types in the interval K7.0-M5.5 (Teff range ~4200-3050 K) observed with the CARMENES…
CARMENES input catalog of M dwarfs: VII. New rotation periods for the survey stars and their correlations with stellar activity
Yutong Shan, Daniel Revilla, Sebastian L. Skrzypinski +40
Abridged: We measured photometric and spectroscopic for a large sample of nearby bright M dwarfs with spectral types from M0 to M9, as part of our continual effort to…
Planetary companions orbiting the M dwarfs GJ 724 and GJ 3988. A CARMENES and IRD collaboration
P. Gorrini, J. Kemmer, S. Dreizler +36
We report the discovery of two exoplanets around the M dwarfs GJ 724 and GJ 3988 using the radial velocity (RV) method. We obtained a total of 153 3.5 m Calar Alto/CARMENES spectra…
The CARMENES search for exoplanets around M dwarfs. A sub-Neptunian mass planet in the habitable zone of HN Lib
E. González-Álvarez, J. Kemmer, P. Chaturvedi +29
We report the discovery of HN Lib b, a sub-Neptunian mass planet orbiting the nearby ( = 6.25 pc) M4.0 V star HN Lib detected by our CARMENES radial-velocity (RV) survey…
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, 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…
RV-detected planets around M dwarfs: Challenges for core accretion models
Martin Schlecker, Remo Burn, Silvia Sabotta +7
Planet formation is sensitive to the conditions in protoplanetary disks, for which scaling laws as a function of stellar mass are known. We aim to test whether the observed populat…
The CARMENES search for exoplanets around M dwarfs: Two Saturn-mass planets orbiting active stars
