viper: High-precision radial velocities from the optical to the infrared (Reaching 3 m/s in the K band of CRIRES+ with telluric modelling)
J. Köhler, M. Zechmeister, A. Hatzes +18
In recent years, a number of new instruments and data reduction pipelines have been developed to obtain high-precision radial velocities (RVs). In particular in the optical, consid…
Abundance analysis of benchmark M dwarfs
T. Olander, U. Heiter, N. Piskunov +2
Abundances of M dwarfs, being the most numerous stellar type in the Galaxy, can enhance our understanding of planet formation processes. They can also be used to study the chemical…
Retrieving day- and nightside atmospheric properties of the ultra-hot Jupiter TOI-2109b. Detection of Fe and CO emission lines and evidence for inefficient heat transport
D. Cont, L. Nortmann, F. Lesjak +32
The ultra-hot Jupiter (UHJ) TOI-2109b marks the lower edge of the equilibrium temperature gap between 3500 K and 4500 K, an unexplored thermal regime that separates KELT-9b, the ho…
Comparative study of small-scale magnetic fields on Boo A using optical and near-infrared spectroscopy
A. Hahlin, O. Kochukhov, P. Chaturvedi +12
Magnetic field investigations of Sun-like stars, using Zeeman splitting of non-polarised spectra, in the optical and H-band have found significantly different magnetic field streng…
Retrieving wind properties from the ultra-hot dayside of WASP-189b with CRIRES
F. Lesjak, L. Nortmann, D. Cont +12
The extreme temperature gradients from day- to nightside in the atmospheres of hot Jupiters generate fast winds in the form of equatorial jets or day-to-night flows. Observations o…
