Modelado de las Distribuciones Espectrales de Energía de tres nuevas estrellas jóvenes de tipo FU Orionis
Abstract
In this work we present the modeling of the spectral energy distributions (SEDs) of three protostellar objects of the FU Orionis type, for which an outburst was observed in the last two years. We applied the code developed by Whitney et al. (ApJ 591, 1049, 2003) to model the SEDs. We derived physical and geometric parameters for each object, which agree with those previously obtained for other FU Orionis type stars. Furthermore, the three objects were studied in their stages of high and low activity. Our results suggest that the disk plays a key role in the outburst event, which is reflected in an increase of at least one order of magnitude of the mass accretion rate from the disk to the central object, with respect to the low activity period.
