Sobre a aula

Last video of Lecture 17. The lecture is dedicated to the main observable characteristics of Classical T Tauri stars, such as emission lines; SED; lithium; rotation; binarity; photospheric spots. We also describe the circumstellar structure and present the other type of TTs, that is the weak-line T Tauri stars.

AGA5741-7 Formação de Estrelas

EMENTA

(1) Estrutura hierárquica do meio interestelar e formação de estrelas.
(2) Propriedades das nuvens moleculares.
(3) Condições iniciais para a fragmentação de nuvens moleculares.
(4) Modelos de colapso protoestelar.
(5) Procura observacional por protoestrelas: Distribuição espectral de energia; Evolução de protoestrelas.
(6) Estrelas pré-sequência principal; Aglomerados estelares; Função de Massa Inicial.
(7) Discos protoplanetários; Fluxos moleculares e jatos; Evolução do disco.

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.
