Obliquity measurement and atmospheric characterization of the WASP-74 planetary system

R. Luque, N. Casasayas-Barris, H. Parviainen +27

We present new transit observations of the hot Jupiter WASP-74 b ( 1860 K) using the high-resolution spectrograph HARPS-N and the multi-colour simultaneous imag…

Search for the sub-stellar lithium depletion boundary in the open star cluster Coma Berenices

Eduardo L. Martín, Nicolas Lodieu, Víctor Sánchez Béjar

We mainly aim to search for the lithium depletion boundary (LDB) among the sub-stellar population of the open star cluster Coma Berenices. We carried out a search for brown dwarf (…

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…

Flare activity and photospheric analysis of Proxima Centauri

Ya. V. Pavlenko, A. Suarez Mascareno, R. Rebolo +3

We present the analysis of emission lines in high-resolution optical spectra of the planet-host star Proxima Centauri (Proxima) classified as a M5.5V\@. We carry out the detailed a…
