Surface brightness-colour relations of Milky Way and Magellanic Clouds classical Cepheids based on Gaia magnitudes
M. C. Bailleul, N. Nardetto, V. Hocdé +12
Aims: We derive SBCRs for classical Cepheids in the Milky Way and in the Magellanic Clouds using the photometric data available in the Gaia database, and we quantify the metallicit…
Gaia FGK Benchmark Stars: spectral library, metallicities and abundances of and Fe-peak elements of the third version
L. Casamiquela, C. Soubiran, P. Jofré +14
The accurate determination of chemical abundances in stars plays a pivotal role in understanding stellar structure and evolution, nucleosynthesis, and the chemical enrichment histo…
Extending the Asteroseismic Calibration of the Stellar Rossby Number
Travis S. Metcalfe, Enrico Corsaro, Alfio Bonanno +2
The stellar Rossby number (Ro) is a dimensionless quantity that is used in the description of fluid flows. It characterizes the relative importance of Coriolis forces on convective…
Predicted asteroseismic detection yield for solar-like oscillating stars with PLATO
M. J. Goupil, C. Catala, R. Samadi +26
We determine the expected yield of detections of solar-like oscillations for the PLATO ESA mission. We used a formulation from the literature to calculate the probability of detect…
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 FGK Benchmark Stars: fundamental Teff and log g of the third version
Caroline Soubiran, Orlagh Creevey, Nadege Lagarde +8
Context. Large spectroscopic surveys devoted to the study of the Milky Way, including Gaia, use automated pipelines to massively determine the atmospheric parameters of millions of…
