Stellar chromospheric activity of 1,674 FGK stars from the AMBRE-HARPS sample I. A catalogue of homogeneous chromospheric activity
J. Gomes da Silva, N. C. Santos, V. Adibekyan +9
We present a catalogue of homogeneous determined chromospheric emission (CE), stellar atmospheric parameters and ages for 1,674 FGK main sequence (MS), subgiant, and giant stars. T…
Pyxel: the collaborative detection simulation framework
Thibaut Prod'homme, Frédéric Lemmel, Matej Arko +5
Pyxel is a novel python tool for end-to-end detection chain simulation i.e. from detector optical effects to readout electronics effects. It is an easy-to-use framework to host and…
On the Use of Field RR Lyrae as Galactic Probes. II. A new S calibration to estimate their metallicity
J. Crestani, M. Fabrizio, V. F. Braga +33
We performed the largest and most homogeneous spectroscopic survey of field RR Lyraes (RRLs). We secured 6,300 high resolution (HR, R35,000) spectra for 143 RRLs (11…
Hot Exoplanet Atmospheres Resolved with Transit Spectroscopy (HEARTS) VI. Non-detection of sodium with HARPS on the bloated super-Neptune WASP-127b
J. V. Seidel, M. Lendl, V. Bourrier +17
WASP-127b is one of the puffiest exoplanets found to date, with a mass only Neptune masses, but a radius larger than Jupiter. It is also located at the border of the Neptune…
The kinematics of young and old stellar populations in nuclear rings of MUSE TIMER galaxies
D. Rosado-Belza, J. Falcón-Barroso, J. H. Knapen +12
Studying the stellar kinematics of galaxies is a key tool in the reconstruction of their evolution. However, the current measurements of the stellar kinematics are complicated by s…
Mapping the stellar age of the Milky Way bulge with the VVV. III. High resolution reddening map
F. Surot, E. Valenti, O. A. Gonzalez +4
The detailed study of the Galactic bulge stellar population necessarily requires an accurate representation of the interstellar extinction particularly toward the Galactic plane an…
