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…

A giant exoplanet orbiting a very low-mass star challenges planet formation models

J. C. Morales, A. J. Mustill, I. Ribas +179

Statistical analyses from exoplanet surveys around low-mass stars indicate that super-Earth and Neptune-mass planets are more frequent than gas giants around such stars, in agreeme…

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…

He I 10830 Å in the transmission spectrum of HD 209458 b

F. J. Alonso-Floriano, I. A. G. Snellen, S. Czesla +27

Context: Recently, the He I triplet at 10830 Å has been rediscovered as an excellent probe of the extended and possibly evaporating atmospheres of close-in transiting planets. This…

The CARMENES search for exoplanets around M dwarfs -- Photospheric parameters of target stars from high-resolution spectroscopy. II. Simultaneous multiwavelength range modeling of activity insensitive lines

V. M. Passegger, A. Schweitzer, D. Shulyak +25

We present precise photospheric parameters of 282 M dwarfs determined from fitting the most recent version of PHOENIX models to high-resolution CARMENES spectra in the visible (0.5…
