Stellar masses and ages in Gaia Data Release 4 from the Final Luminosity Age Mass Estimator algorithm
Orlagh L. Creevey, Laia Casamiquela, Yveline Lebreton +23
The masses and ages of stars are key quantities for understanding exoplanetary, stellar, and galactic evolution. In the context of Gaia, these parameters provide insights into the…
Chemical Compositions of Field and Globular Cluster RR~Lyrae Stars: II. omega Centauri
D. Magurno, C. Sneden, G. Bono +21
We present a detailed spectroscopic analysis of RR Lyrae (RRL) variables in the globular cluster NGC 5139 (omega Cen). We collected optical (4580-5330 A), high resolution (R = 34,0…
New determination of abundances and stellar parameters for a set of weak G-band stars
A. Palacios, G. Jasniewicz, T. Masseron +3
Weak G-band (wGb) stars are very peculiar red giants almost devoided of carbon and often mildly enriched in lithium. Despite their very puzzling abundance patterns, very few detail…
On the alpha-element gradients of the Galactic thin disk using Cepheids
K. Genovali, B. Lemasle, R. da Silva +16
We present new homogeneous measurements of Na, Al and three alpha-elements (Mg, Si, Ca) for 75 Galactic Cepheids. The abundances are based on high spectral resolution (R ~ 38,000)…
On the metallicity distribution of classical Cepheids in the Galactic inner disk
K. Genovali, B. Lemasle, G. Bono +10
We present homogeneous and accurate iron abundances for almost four dozen (47) of Galactic Cepheids using high-spectral resolution (R40,000) high signal-to-noise ratio (S/N $…
Fundamental properties of the Population II fiducial stars HD 122563 and Gmb 1830 from CHARA interferometric observations
O. L. Creevey, F. Thévenin, T. S. Boyajian +17
We have determined the angular diameters of two metal-poor stars, HD 122563 and Gmb 1830, using CHARA and Palomar Testbed Interferometer observations. For the giant star HD 122563,…
