Early stages of star formation
The main goal of this reasearch is to improve our basic knowledge of the physical processes associated with the early stages of the star formation. In particular, we study the basic ingredients of the process of star (and planet) formation: gravitational collapse of envelopes of gas and dust, protoplanetary accretion disks, outflows, and maser emission. We analyze the differences and similarities between the low-mass and high-mass star formation, both from an observational and theoretical point of view, making a special emphasis in high-angular resolution studies.
