A mapping method of age estimation for binary stars: Application to the Centauri system A and B

F. Thévenin, V. A. Baturin, A. V. Oreshina +4

Given the wealth of data provided by Gaia and the upcoming PLATO mission, it is essential to improve stellar models to obtain accurate stellar ages. Our objective is to apply a map…

The Gaia RVS Benchmark Stars. III . Confirmed and New High Radial Velocity Stars From Gaia DR3

Elisabetta Caffau, David Katz, Piercarlo Bonifacio +12

High-velocity stars are interesting targets to unveil the formation of the Milky Way. In fact they can be recently accreted from an infalling dwarf galaxies or they can be the resu…

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…

Benchmarking the effective temperature scale of red giant branch stellar models: the case of the metal-poor halo giant HD 122563

O. L. Creevey, S. Cassisi, F. Thévenin +2

There is plenty of evidence in the literature of significant discrepancies between the observations and models of metal-poor red giant branch stars, in particular regarding the eff…

The Gaia RVS benchmark stars II. A sample of stars selected for their Gaia high radial velocity

E. Caffau, D. Katz, A. Gómez +16

The Gaia satellite has already provided the astronomical community with three data releases, and the Radial Velocity Spectrometer (RVS) on board Gaia has provided the radial veloci…

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: 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…

A near-infrared interferometric survey of debris-disk stars. VII. The hot/warm dust connection

O. Absil, L. Marion, S. Ertel +10

(abridged) Context. The origin of hot exozodiacal dust and its connection with outer dust reservoirs remains unclear. Aims. We aim to explore the possible connection between hot ex…

A near-infrared interferometric survey of debris-disk stars. VI. Extending the exozodiacal light survey with CHARA/JouFLU

Paul D. Nunez, N. J. Scott, B. Mennesson +11

We report the results of high-angular-resolution observations that search for exozodiacal light in a sample of main sequence stars and sub-giants. Using the "jouvence" of the fiber…

An empirical recipe for inelastic hydrogen-atom collisions in non-LTE calculations

Rana Ezzeddine, Thibault Merle, Bertrand Plez +3

We investigate the role of hydrogen collisions in NLTE spectral line synthesis, and introduce a new general empirical recipe to determine inelastic charge transfer (CT) and bound-b…

Asteroseismic constraints for Gaia

O. L. Creevey, F. Thévenin

Distances from the Gaia mission will no doubt improve our understanding of stellar physics by providing an excellent constraint on the luminosity of the star. However, it is also c…

A near-infrared interferometric survey of debris disk stars. I. Probing the hot dust content around epsilon Eridani and tau Ceti with CHARA/FLUOR

E. Di Folco, O. Absil, J. -C. Augereau +11

We probed the first 3AU around tau Ceti and epsilon Eridani with the CHARA array (Mt Wilson, USA) in order to gauge the 2micron excess flux emanating from possible hot dust grains…
