Simulation of the Continuous Spectrum of Substars with Protoplanetary Discs
Abstract
The continuous spectra of the substars with surrounding protoplanetary disks were calculated. The results reveal that protoplanetary disc average temperature decreases to 3 K during the period of 5 Myr for substars with masses 0.01MSun and during the period of 160 Myr for substars with masses 0.08MSun. Estimations of protoplanetary discs flux maximum depending on the substar mass at the age of 1 Myr are: 4.6 kJy (for 0.01MSun) and 3.4 MJy (for 0.08MSun). Maximum of protoplanetary disc radiation before it reaches the temperature of the cosmic microwave background changes within the ranges: from 0.07 mm to 0.58 mm (for substar mass 0.01MSun) and from 0.02 mm to 0.29 mm (for substar mass 0.08MSun).
