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…
Gaia Early Data Release 3: The Gaia Catalogue of Nearby Stars
Gaia Collaboration, R. L. Smart, L. M. Sarro +420
We produce a clean and well-characterised catalogue of objects within 100\,pc of the Sun from the \G\ Early Data Release 3. We characterise the catalogue through comparisons to the…
Gaia Early Data Release 3: Acceleration of the solar system from Gaia astrometry
Gaia Collaboration, S. A. Klioner, F. Mignard +414
Context. Gaia Early Data Release 3 (Gaia EDR3) provides accurate astrometry for about 1.6 million compact (QSO-like) extragalactic sources, 1.2 million of which have the best-quali…
A precise architecture characterization of the Men planetary system
M. Damasso, A. Sozzetti, C. Lovis +97
The bright star Men was chosen as the first target for a radial velocity follow-up to test the performance of ESPRESSO, the new high-resolution spectrograph at the ESO's Very-L…
Characterization of the K2-38 planetary system. Unraveling one of the densest planets known to date
B. Toledo-Padrón, C. Lovis, A. Suárez Mascareño +90
We characterized the transiting planetary system orbiting the G2V star K2-38 using the new-generation echelle spectrograph ESPRESSO. We carried out a photometric analysis of the av…
TESS Asteroseismic Analysis of the Known Exoplanet Host Star HD 222076
Chen Jiang, Timothy R. Bedding, Keivan G. Stassun +24
The Transiting Exoplanet Survey Satellite (TESS) is an all-sky survey mission aiming to search for exoplanets that transit bright stars. The high-quality photometric data of TESS a…
