Magnetic Activity Cycles and Rotation in Planet-hosting and Non-hosting Solar-type Stars
Amina Boulkaboul, Alessandro Sozzetti, Caroline Soubiran +1
We analyze periodicities in radial velocity (RV) measurements and magnetic activity indicators (S-index and BIS) for 767 Gaia RV standard stars to distinguish between stellar activ…
Gaia DR3 high radial velocity stars: Genuine fast-moving objects or outliers?
D. Katz, A. Gómez, E. Caffau +39
The third Gaia data release includes 33.8 million radial velocity measurements, extending to a magnitude of G_RVS = 14. To reach this magnitude limit, spectra were processed down t…
Magnetic activity and differential rotation of HIP12653
Amina Boulkaboul, Lotfi Yelles Chaouche, Alessandro C. Lanzafame +1
We present a spectroscopic and photometric study of HIP12653 to investigate its magnetic cycle and differential rotation. Using HARPS archival spectra matched with MARCS-AMBER theo…
Gaia Data Release 3: spectroscopic binary-star orbital solutions. The SB1 processing chain
E. Gosset, Y. Damerdji, T. Morel +7
Gaia is an astrometric space experiment that is measuring positions, proper motions as well as parallaxes for a huge number of stars. It operates a medium-dispersion spectrometer,…
Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry
Gaia Collaboration, P. Panuzzo, T. Mazeh +412
Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…
Gaia Focused Product Release: Sources from Service Interface Function image analysis -- Half a million new sources in omega Centauri
Gaia Collaboration, K. Weingrill, A. Mints +400
Gaia's readout window strategy is challenged by very dense fields in the sky. Therefore, in addition to standard Gaia observations, full Sky Mapper (SM) images were recorded for ni…
