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…
Rotational evolution of slow-rotator sequence stars. II. Modeling the wind braking and the rotational coupling in the entire mass range of solar-like stars
F. Spada, A. C. Lanzafame
In recent years, ground- and space-based photometric surveys have characterized the rotational evolution of solar-like stars to an unprecedented level of detail. In this work we fo…
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…
Rotation of young solar-type stars as seen by Gaia and K2
Sylvain N. Breton, Elisa Distefano, Alessandro C. Lanzafame +1
Accurate surface rotation measurements are crucial to estimate stellar ages and improve our understanding of stellar rotational evolution. Comparisons of datasets obtained from dif…
The Gaia-ESO Survey: Projected Rotational Velocities of B stars in the Carina Nebula
W. Santos, S. Daflon, J. V. Sales Silva +19
The Carina Nebula is an active star-forming region with several open clusters rich in massive OB stars, thus making it an optimal target for studying stellar properties such as rot…
The Gaia-ESO Survey: Calibrating the lithium-age relation with open clusters and associations. II. Expanded cluster sample and final membership selection
M. L. Gutiérrez Albarrán, D. Montes, H. M. Tabernero +26
The Li abundance observed in pre-main sequence and main sequence late-type stars is strongly age-dependent, but also shows a complex pattern depending on several parameters, such a…
