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…
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…
Stars and brown dwarfs in the sigma Orionis cluster. IV. IDS/INT and OSIRIS/GTC spectroscopy and Gaia DR2 astrometry
J. A. Caballero, A. de Burgos, F. J. Alonso-Floriano +3
Context. Only a few open clusters are as important for the study of stellar and substellar objects, and their formation and evolution, as the young sigma Orionis cluster. However,…
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. Two temperate Earth-mass planet candidates around Teegarden's Star
M. Zechmeister, S. Dreizler, I. Ribas +182
Context. Teegarden's Star is the brightest and one of the nearest ultra-cool dwarfs in the solar neighbourhood. For its late spectral type (M7.0V), the star shows relatively little…
