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…

Stellar Activity Cycles

Sandra V. Jeffers, Rene Kiefer, Travis S. Metcalfe

The magnetic field of the Sun is generated by internal dynamo process with a cyclic period of 11 years or a 22 year magnetic cycle. The signatures of the Sun's magnetic cycle are o…

Asteroseismology and Spectropolarimetry of the Exoplanet Host Star Serpentis

Travis S. Metcalfe, Derek Buzasi, Daniel Huber +31

The bright star Ser hosts a hot Neptune with a minimum mass of 13.6 and a 15.5 day orbit. It also appears to be a solar analog, with a mean rotation period of 25.8 d…

The CARMENES search for exoplanets around M dwarfs. Behaviour of the Paschen lines during flares and quiescence

B. Fuhrmeister, S. Czesla, J. H. M. M. Schmitt +17

The hydrogen Paschen lines are known activity indicators, but studies of them in M~dwarfs during quiescence are as rare as their reports in flare studies. This situation is mostly…

Modeling the Chromosphere and Transition Region of Planet-hosting Star GJ 436

Dominik Hintz, Sarah Peacock, Travis Barman +12

Ahead of upcoming space missions intending to conduct observations of low-mass stars in the ultraviolet (UV) spectral region it becomes imperative to simultaneously conduct atmosph…

Constraints on Magnetic Braking from the G8 Dwarf Stars 61 UMa and Cet

Travis S. Metcalfe, Klaus G. Strassmeier, Ilya V. Ilyin +11

During the first half of their main-sequence lifetimes, stars rapidly lose angular momentum to their magnetized winds, a process known as magnetic braking. Recent observations sugg…
