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.

AGA5741 - Lecture 01 Historical overview

Vera Jatenco Silva Pereira

Historical overview of the physical laws necessary to understand the star formation.

AGA5741 - Lecture 02 – The Interstellar Medium

Vera Jatenco Silva Pereira

Description of the contents of the interstellar medium and their properties such as temperature, density, composition and opacity.

AGA5741 - Lecture 03 – Molecular Clouds

Vera Jatenco Silva Pereira

Description of the large scale properties like mass and size of molecular clouds in our Galaxy.

AGA5741 - Lecture 04 – Molecular Clouds

Vera Jatenco Silva Pereira

Description of the gravitational collapse criterium of a molecular cloud and their fragmentation.

AGA5741 - Lecture 05 – Molecular Clouds

Vera Jatenco Silva Pereira

Description of the large scale properties of molecular clouds in our Galaxy, in particular spatial structure.

AGA5741 - Lecture 06 – Molecular Clouds Cores

Vera Jatenco Silva Pereira

Description of the properties of cloud cores inside the molecular clouds complex and how to study these dense regions.

AGA5741 - Lecture 07 – Molecular Clouds Stability

Vera Jatenco Silva Pereira

Study the stability of a core with well-defined outer boundaries. The analysis is done using the Virial theorem.

AGA5741 - Lecture 08 – Models for Protostellar Collapse

Vera Jatenco Silva Pereira

Models using equilibrium hydrostatic for the initial equilibrium state with spherical geometry.

AGA5741 - Lecture 09 – Core collapse and the effects of rotation

Vera Jatenco Silva Pereira

Models using equilibrium hydrostatic for the initial equilibrium state with spherical geometry and the effects of rotation.

AGA5741 - Lecture 10 – Accretion disks: theory

Vera Jatenco Silva Pereira

In this lecture we will see the theory of accretion disks and use two approximations.
