Simultaneous photometric and CARMENES spectroscopic monitoring of fast-rotating M dwarf GJ 3270. Discovery of a post-flare corotating feature
E. N. Johnson, S. Czesla, B. Fuhrmeister +33
Context: Active M dwarfs frequently exhibit large flares, which can pose an existential threat to the habitability of any planet in orbit in addition to making said planets more di…
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. The He I infrared triplet lines in PHOENIX models of M2-3 V stars
D. Hintz, B. Fuhrmeister, S. Czesla +25
The He I infrared (IR) line at a vacuum wavelength of 10833 A is a diagnostic for the investigation of atmospheres of stars and planets orbiting them. For the first time, we study…
The CARMENES search for exoplanets around M dwarfs. The He I triplet at 10830 across the M dwarf sequence
B. Fuhrmeister, S. Czesla, L. Hildebrandt +24
The He I infrared (IR) triplet at 10830 AA is an important activity indicator for the Sun and in solar-type stars, however, it has rarely been studied in relation to M dwarfs to da…
The CARMENES search for exoplanets around M dwarfs. Chromospheric modeling of M2-3 V stars with PHOENIX
D. Hintz, B. Fuhrmeister, S. Czesla +26
Chromospheric modeling of observed differences in stellar activity lines is imperative to fully understand the upper atmospheres of late-type stars. We present one-dimensional para…
The CARMENES search for exoplanets around M dwarfs. Activity indicators at visible and near-infrared wavelengths
P. Schöfer, S. V. Jeffers, A. Reiners +21
The CARMENES survey is searching for Earth-like planets orbiting M dwarfs using the radial velocity method. Studying the stellar activity of the target stars is important to avoid…
