Context. Double-lined eclipsing binaries allow the direct determination of masses and radii, which are key for testing stellar models. With the launch of the...

In this paper we present a new, accurate determination of the three components of the absolute space velocity of the Galactic globular cluster NGC 6397 (l≃338°...

We demonstrate in this work that it is possible to derive spectra of integrated absorption lines for any type stellar system using the GTC/OSIRIS Tunable...

Context. During the past decade, several studies reported a correlation between chemical abundances of stars and condensation temperature (also known as Tc...

Context. Symbiotic binaries exhibit a wide range of photometric variability across different timescales. These changes can be attributed to factors such as...

Studies of Galactic chemical, and dynamical evolution in the solar neighborhood depend on the availability of precise atmospheric parameters (effective...

We have obtained adaptive optics images and accurate radial velocities for 7 very low mass objects, In the course of a long term effort to determine accurate...

We present improved visual and near-infrared empirical mass-luminosity relations for very low mass stars (M

Context. Wide-field spectrometers are needed to deal with current astrophysical challenges that require multiband observations at millimeter wavelengths. An...
