Dados da disciplina

Instituição Instituto de Astronomia, Geofísica e Ciências Atmosféricas Objetivo

O curso fornece uma introdução à formação de estrelas focada na pré-sequência principal (estrelas de baixa massa e de massa intermediária). Os tópicos começam na escala galáctica, diminuindo até as escalas de estrelas individuais e seus discos.
