Radial velocity photon limits for the dwarf stars of spectral classes F--M

Ansgar Reiners, Mathias Zechmeister

The determination of extrasolar planet masses with the radial velocity (RV) technique requires spectroscopic Doppler information from the planet's host star, which varies with stel…

Ionized calcium in the atmospheres of two ultra-hot exoplanets WASP-33b and KELT-9b

F. Yan, N. Casasayas-Barris, K. Molaverdikhani +25

Ultra-hot Jupiters are emerging as a new class of exoplanets. Studying their chemical compositions and temperature structures will improve the understanding of their mass loss rate…

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…

Remote sensing of exoplanetary atmospheres with ground-based high-resolution near-infrared spectroscopy

D. Shulyak, M. Rengel, A. Reiners +2

Thanks to the advances in modern instrumentation we have learned about many exoplanets that span a wide range of masses and composition. Studying their atmospheres provides insight…

Water vapor detection in the transmission spectra of HD 209458 b with the CARMENES NIR channel

A. Sánchez-López, F. J. Alonso-Floriano, M. López-Puertas +31

Aims: We aim at detecting HO in the atmosphere of the hot Jupiter HD 209458 b and perform a multi-band study in the near infrared with CARMENES. Methods: The HO absorption…

Red Dots: A temperate 1.5 Earth-mass planet in a compact multi-terrestrial planet system around GJ1061

S. Dreizler, S. V., Jeffers +17

Small low-mass stars are favourable targets for the detection of rocky habitable planets. In particular, planetary systems in the solar neighbourhood are interesting and suitable f…
