Early Earth and Life

A knowledge of how life originated and evolved on Earth is of central importance in historical Sciences (Geology, Biologie, Astrobiologie). To obtain a general view of the interelated processes (geodynamic, climatic, oceanic, biological) involved in the evolution of the early Earth during the first 2.5 Ga of its history (Hadean, Archean, Early Proterozic). Institute of Geosciences (IGc) São Paulo main campus Less than 200 Ma after its formation, the Earth holds all the attributes of a modern Earth (core, protolithosphere, oceans and atmosphere). However, it will take nearly two billion years to shape terrestrial geodynamics and the major bio-geochemical cycles as we know them today. What happened between the two? When and how did the plate tectonics begin? How did life appear on Earth and in what environments? What are the first traces of life? Is there a link between crustal growth, the diversification of microbial life and the evolution of the composition of the atmosphere? Is oxygenation of the atmosphere and oceans of biological or abiotic origin? These are, among others, the questions we will address during this course, as follows: 1) 4.5-4.4 Ga, accretion and differentiation core-mantle, late veneer, formation of the Moon 2) 4.4-4.1 Ga, first zircons, first continents, first oceans 3) Early Earth geodynamics 4) Early Oceans 5) Early atmosphere 6) Early life Marly Babinski, Pascal Andre Marie Philippot 20 GMG5838 4 Oral presentation given by individual students on key scientific issues related to the evolution of the primitive Earth and early Life.

Radiative Processes

The goal of every astrophysical model is to provide a quantitative interpretation of astrophysical observations. This discipline is hence fundamental to students which aim to pursue their MSc, PhD and post-graduate studies in Astrophysics. Study the basic processes involved in the production of radiation that we receive from celestial bodies, as well as the interaction of this radiation with intervening matter.

Stellar Populations of galaxies

The aim of this course is the study of stellar populations in our Galaxy, and in other galaxies. The populations in our Galaxy, from the halo, bulge, thin and thick disks, can be studied in terms of their ages, metallicities, abundances, kinematics, and their evolution in time and space. We also introduce the basic ingredients of evolution of galaxies: stellar evolution, chemical evolution, and spectroscopy of individual stars and composite stellar populations. Different types of galaxies are studied: elliptical, spiral, irregular galaxies, and HII regions. The program is concluded with the analysis of composite spectra of galaxies, using codes from the literature. The distribution of stellar populations in galaxies is studied, making that these studies comprehend most objects in the Universe: the galaxies studied through the stars that form them. In astrophysics, it is therefore a fundamental course. Institute of Astronomy, Geophysics and Atmospheric Sciences (IAG) São Paulo main campus Basics of stellar evolution. Basics of nucleosynthesis.

South American Plate Geophysics

This course deals with formation models for the main geotectonic provinces, how they are set in the past and in the present; the main characteristics of the continental and oceanic lithosphere using geophysical data and how to integrate this data to the tectonic knowledge of South American plate. This course aims to provide information on the main geotectonic provinces of South America and about the geophysical surveys in great scale. It is expected that the students can use all the information to infer relations among geology and geophysics.

Welding Engineering

The purpose of this course is to give familiar with the concepts and terminology in welding engineering. Student will understand how welding design is built on a foundation of heat flow stress, structural analysis and fitness for services. In this course the students will learn the basic theory of various materials joining processes including arc, resistance, solid state, and high energy density welding. 1.
