Description
Spectra in the wavelength range 4230-9150 Å and the first
light curves of Z Vul in the infrared J, H and K bands are presented.
Our infrared JHK light curves and radial velocities, together with
published radial velocity and UBV data are analyzed in order to
determine a new set of stellar parameters. This allows us to determine
new absolute parameters of the stellar components, the interstellar
reddening and the distance to the system. We discuss the rotation of the
primary star, finding that must be rotating faster than synchronous.
From the visual-infrared photometry we find no evidence of IR
excess in the system.

Binary Stars
The study of binary stars is essential to stellar astrophysics. A large number of stars form and evolve within binary systems. Therefore, their study is fundamental to understand stellar and galactic evolution. Particularly relevant is that binary systems are still the best source of precise stellar mass and radius measurements. Research lines

Helio and Astero-Seismology and Exoplanets Search
The principal objectives of this project are: 1) to study the structure and dynamics of the solar interior, 2) to extend this study to other stars, 3) to search for extrasolar planets using photometric methods (primarily by transits of their host stars) and their characterization (using radial velocity information) and 4) the study of the planetary
