Advanced Classification of Hot Subdwarf Binaries Using Artificial Intelligence Techniques and Gaia DR3 data
C. Viscasillas Vázquez, E. Solano, A. Ulla +11
Hot subdwarfs are compact blue evolved objects, burning helium in their cores surrounded by a tiny hydrogen envelope. Most models agree on a common envelope binary evolution scenar…
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…
Gaia Focused Product Release: Radial velocity time series of long-period variables
Gaia Collaboration, M. Trabucchi, N. Mowlavi +403
The third Gaia Data Release (DR3) provided photometric time series of more than 2 million long-period variable (LPV) candidates. Anticipating the publication of full radial-velocit…
Gaia Data Release 3: Analysis of the Gaia BP/RP spectra using the General Stellar Parameterizer from Photometry
R. Andrae, M. Fouesneau, R. Sordo +80
We present the General Stellar Parameterizer from Photometry (GSP-Phot), which is part of the astrophysical parameters inference system (Apsis). GSP-Phot is designed to produce a h…
Gaia Data Release 3: Apsis II -- Stellar Parameters
M. Fouesneau, Y. Frémat, R. Andrae +78
The third Gaia data release contains, beyond the astrometry and photometry, dispersed light for hundreds of millions of sources from the Gaia prism spectra (BP and RP) and the spec…
Gaia Data Release 3: Catalogue Validation
C. Babusiaux, C. Fabricius, S. Khanna +40
The third gaia data release (DR3) provides a wealth of new data products. The early part of the release, Gaia EDR3, already provided the astrometric and photometric data for nearly…
Gaia Data Release 3. Stellar chromospheric activity and mass accretion from Ca II IRT observed by the Radial Velocity Spectrometer
A. C. Lanzafame, E. Brugaletta, Y. Frémat +82
The Gaia Radial Velocity Spectrometer provides the unique opportunity of a spectroscopic analysis of millions of stars at medium-resolution in the near-infrared. This wavelength ra…
Identification of new hot subdwarf binary systems by means of Virtual Observatory tools
E. Solano, A. Ulla, E. Pérez-Fernández +7
The estimation of the binary fraction of hot subdwarfs is key to shed light on the different evolution scenarios proposed to explain the loss of the hydrogen envelope during the re…
Gaia Data Release 2: Variable stars in the colour-absolute magnitude diagram
Gaia Collaboration, L. Eyer, L. Rimoldini +14
The ESA Gaia mission provides a unique time-domain survey for more than 1.6 billion sources with G ~ 21 mag. We showcase stellar variability across the Galactic colour-absolute mag…
Gaia Data Release 2: Observational Hertzsprung-Russell diagrams
Gaia Collaboration, C. Babusiaux, F. van Leeuwen +450
We highlight the power of the Gaia DR2 in studying many fine structures of the Hertzsprung-Russell diagram (HRD). Gaia allows us to present many different HRDs, depending in partic…
Gaia Data Release 1. Testing the parallaxes with local Cepheids and RR Lyrae stars
Gaia Collaboration, G. Clementini, L. Eyer +588
Parallaxes for 331 classical Cepheids, 31 Type II Cepheids and 364 RR Lyrae stars in common between Gaia and the Hipparcos and Tycho-2 catalogues are published in Gaia Data Release…
