We report mm and cm observations toward three different transitional disks around stars with masses between ~0:4 and ~ 2 M and ages between ~ 1 and ~ 10 Myr. These observations, obtained with the Very Large Array (VLA) and the Atacama Large Millimeter/Submillimeter Array (ALMA), have allowed us to study the thermal continuum emission of the large dust grains as well as the free-free emission from ionized gas in the disk and its surroundings. In addition, we have complemented these observations with the modeling of the dust thermal emission using self-consistent radiative transfer codes for accretion disks irradiated by its central star that calculate their temperature and density distribution, as well as the predicted dust emission. 2017-01-31T12:00:28Z 2017-01-31T12:00:28Z 2016 2016-10-28 doctoral thesis Macías Quevedo, E.
