We present optical spectroscopy of MWC 656 and MWC 148, the proposed optical counterparts of the gamma-ray sources AGL J2241+4454 and HESS J0632+0 57, respectively. The main parameters of the Halpha emission line (EW, FWHM and centroid velocity) in t

[eng] The current trend in exoplanet research focuses on the detection and characterisation of Earth-sized planets, and the study of their potential subtle and tenuous atmospheres. The aim of this thesis is the development of tools and simulation cod

Després del descobriment dels primers exoplanetes fa unes tres dècades, la detecció i caracterització de companys planetaris s’ha convertit en un tema de recerca prominent, especialment la cerca de planetes semblants a la Terra, cossos rocosos

Most of the efforts on the search and characterization of Earth-like exoplanets are currently focused on low mass stars. Some important properties related to the structure and processes in this type of stars are still unknown, so a careful characteri

The comparison between stellar structure models and observations of low-mass stars revealed that the stellar radii predicted by models for these stars are about 10% lower than observed, while effective temperatures are about 5% higher. Eclipsing bina

[eng] The Andromeda Galaxy (M31) is an excellent distance calibrator in the Cosmological Distance Ladder. We present the first direct distance determination to M31 using eclipsing binaries (EBs). EBs provides direct distance determinations because th
