Se ha conseguido explicar la física de los chorros de rayos X observados recientemente con el satélite Hinode mediante la combinación de análisis de datos...
OBSERVATIONAL TESTS OF THE PROCESSES OF NUCLEOSYNTHESIS IN THE UNIVERSE.
The sample of metal rich stars with and without planets has been extended in 2007 and the stellar parameters and metallicities have been obtained. The first...
We tested the theoretical prediction that the straightest dust lanes in bars are found in strongly barred galaxies, or more specifically, that the degree of...
On the magnetic nature of quiet-Sun chromospheric grains
CaII Kgrains, i.e., intermittent, short-lived (about 1 minute), periodic (2-4 minutes), pointlike chromospheric brightenings, are considered to be the...
On the origin of stars with and without planets. Tc trends and clues to Galactic evolution.
We explore a sample of 148 solar-like stars to search for a possible correlation between the slopes of the abundance trends versus condensation temperature...
On the Probable Existence of an Abrupt Magnetization in the Upper Chromosphere of the Quiet Sun.
A long-standing issue in solar astrophysics concerns the strength and structure variations with height of the magnetic field in the chromosphere of the quiet...
Optical Photometric GTC/OSIRIS Observations of the Young Massive Association Cygnus OB2.
In order to fully understand the gravitational collapse of molecular clouds, the star formation process, and the evolution of circumstellar disks, these...
Orbital and Physical Properties of the sigma Ori Aa, Ab, B Triple System.
We provide a complete characterization of the astrophysical properties of the σ Ori Aa, Ab, B hierarchical triple system and an improved set of orbital...
