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 (…
First Detection of Two Superoutbursts during Rebrightening Phase of a WZ Sge-type Dwarf Nova: TCP J21040470+4631129
Yusuke Tampo, Kojiguchi Naoto, Keisuke Isogai +51
We report photometric and spectroscopic observations and analysis of the 2019 superoutburst of TCP J21040470+4631129. This object showed a 9-mag superoutburst with early superhumps…
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…
Multicolour photometry for exoplanet candidate validation
Hannu Parviainen, Brandon Tingley, Hans. J. Deeg +17
Context. The TESS and PLATO missions are expected to find vast numbers of new transiting planet candidates. However, only a fraction of these candidates will be legitimate planets,…
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…
