The CARMENES search for exoplanets around M dwarfs. Telluric absorption corrected high S/N optical and near-infrared template spectra of 382 M dwarf stars

E. Nagel, S. Czesla, A. Kaminski +22

Light from celestial objects interacts with the molecules of the Earth's atmosphere, resulting in the production of telluric absorption lines in ground-based spectral data. Correct…

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 deep transfer learning method to determine Teff and [M/H] of target stars

A. Bello-García, V. M. Passegger, J. Ordieres-Meré +17

The large amounts of astrophysical data being provided by existing and future instrumentation require efficient and fast analysis tools. Transfer learning is a new technique promis…

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. Line-by-line sensitivity to activity in M dwarfs

M. Lafarga, I. Ribas, M. Zechmeister +17

Radial velocities (RVs) measured from high-resolution stellar spectra are routinely used to detect and characterise orbiting exoplanet companions. The different lines present in st…

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…
