Spectroscopic characterisation of CARMENES target candidates from FEROS, CAFE and HRS high-resolution spectra
V. M. Passegger, A. Reiners, S. V. Jeffers +9
CARMENES (Calar Alto high-Resolution search for M dwarfs with Exoearths with Near-infrared and optical Echelle Spectrographs) started a new planet survey on M-dwarfs in January thi…
Magnetic fields in M-dwarfs: quantitative results from detailed spectral synthesis in FeH lines
D. Shulyak, A. Reiners, S. Wende +3
Strong surface magnetic fields are ubiquitously found in M-dwarfs with mean intensities on the order of few thousand Gauss-three orders of magnitude higher than the mean surface ma…
Investigation of magnetically sensitive FeH lines
Sebastian Wende, Ansgar Reiners, Andreas Seifahrt +2
M-type stars exhibit strong magnetic fields towards decreasing effective temperatures. The measurement of these fields is complicated due to missing indicators. Molecular FeH lines…
Modelling the molecular Zeeman effect in M-dwarfs: methods and first results
D. Shulyak, A. Reiners, S. Wende +3
We present first quantitative results of the surface magnetic field measurements in selected M-dwarfs based on detailed spectra synthesis conducted simultaneously in atomic and mol…
CRIRES spectroscopy and empirical line-by-line identification of FeH molecular absorption in an M dwarf
S. Wende, A. Reiners, A. Seifahrt +1
Molecular FeH provides a large number of sharp and isolated absorption lines that can be used to measure radial velocity, rotation, or magnetic field strength with high accuracy. O…
3D simulations of M star atmosphere velocities and their influence on molecular FeH lines
S. Wende, A. Reiners, H. -G. Ludwig
We present an investigation of the velocity fields in early to late M-type star hydrodynamic models, and we simulate their influence on FeH molecular line shapes. The M star model…
