We study the presence and importance of stellar migration in the evolution of 17 Milky-Way like disc galaxies with stellar mass 10 < log(M */M ⊙) < 11 from the...
Stellar models for a wide range of initial chemical compositions until helium burning. I. From X=0.60 to X=0.80 for Z=0.02.
New grids of stellar evolutionary models are presented for a wide range of initial hydrogen content around the solar composition. These compositions are (X, Z)...
Stellar models for a wide range of initial chemical compositions until helium burning. II. From X=0.63 to X=0.80, for Z=0.01.
Three new grids of stellar evolutionary models with Z=0.01 are presented for the following values of initial hydrogen content X_i_=0.80, 0.73 and 0.63. The...
Stellar models with rotation: an exploratory application to pre-main sequence Lithium Depletion.
Over the last 20 years, the surface abundance of Li has been derived for a significant number of low mass pre-main sequence (PMS) stars. Several works have...
Stellar Multiplicity Meets Stellar Evolution and Metallicity: The APOGEE View
We use the multi-epoch radial velocities acquired by the Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey to perform a large-scale...
Stellar occultation by (119951) 2002 KX14 on April 26, 2012
Context. Trans-Neptunian objects (TNOs) are important bodies, but very little is known about their basic physical properties such as size, density, and albedo...
Stellar p-mode oscillations signal in Procyon A from MOST data
Recently, Matthews et al. (2004, Nature, 430, 51) claim a null detection of p-mode oscillations in Procyon A from 32 days of nearly continuous photometric...
Stellar p-modes oscillation measurements in solar-like star signals: α Centauri A as an example
Context: This paper deals with the analysis of observational data series of solar-like stars. In dealing with observations of solar-like stellar oscillations...
Stellar parameters of early-M dwarfs from ratios of spectral features at optical wavelengths
Context. Low-mass stars have been recognised as promising targets in the search for rocky, small planets with the potential of supporting life. As a consequence...
