Breve Histórico Dos Meteoritos Brasileiros
Parte 1 Breve histórico dos meteoritos brasileiros Maria Elizabeth Zucolotto (MN/UFRJ) Os meteoritos se prestam ao estudo das condições e processos físicos da formação do sistema solar. São fragmentos de corpos em diversos estágios de diferenciação planetária, sendo encontrados desde meteoritos primitivos, de composição solar, até representantes da crosta, manto e núcleo de corpos planetários diferenciados. A história dos meteoritos brasileiros está diretamente ligada à história da meteorítica, pois o Bendegó foi descoberto em 1784 quando ainda se desconhecia a natureza extraterrestre dos meteoritos. O Bendegó foi durante muitos anos o maior meteorito em exposição em um museu. O Brasil possui hoje apenas 62 meteoritos certificados, alguns muito importantes como o Angra dos Reis, que deu origem a uma classe de meteoritos, os “angritos”. Pedras sagradas Embora os meteoritos só tenham sido aceitos pela ciência como objetos de origem extraterrestre no início do século 19, o fenômeno de queda de rochas e ferro sobre a Terra (meteoros e bólidos) era conhecido desde a antiguidade. Papiros egípcios, de 4 mil anos, registram objetos luminosos riscando os céus numa representação típica de queda de meteoritos, isto é, queda de objetos sólidos no chão. Escritos gregos, de 3,5 mil e 2,5 mil anos, mencionam a queda de pedras e ferro do céu. Provavelmente pela natureza extraterrestre e supostos poderes mágicos, al- guns meteoritos foram objetos de veneração em várias civilizações, dos quais só restaram algumas descrições históricas. A mais interessante é a de Tito Lívio rela- tando que, em 204 AEC, a pedra negra que simbolizava a Magna Mater (Grande Mãe, também chamada Cibele), foi levada para Roma em situação interessante: os exércitos de Aníbal tinham penetrado nos territórios romanos disseminan- do o pânico entre a população. -

Compiled Thesis
SPACE ROCKS: a series of papers on METEORITES AND ASTEROIDS by Nina Louise Hooper A thesis submitted to the Department of Astronomy in partial fulfillment of the requirement for the Bachelor’s Degree with Honors Harvard College 8 April 2016 Of all investments into the future, the conquest of space demands the greatest efforts and the longest-term commitment, but it also offers the greatest reward: none less than a universe. — Daniel Christlein !ii Acknowledgements I finished this senior thesis aided by the profound effort and commitment of my thesis advisor, Martin Elvis. I am extremely grateful for him countless hours of discussions and detailed feedback on all stages of this research. I am also grateful for the remarkable people at Harvard-Smithsonian Center for Astrophysics of whom I asked many questions and who took the time to help me. Special thanks go to Warren Brown for his guidance with spectral reduction processes in IRAF, Francesca DeMeo for her assistance in the spectral classification of our Near Earth Asteroids and Samurdha Jayasinghe and for helping me write my data analysis script in python. I thank Dan Holmqvist for being an incredibly helpful and supportive presence throughout this project. I thank David Charbonneau, Alicia Soderberg and the members of my senior thesis class of astrophysics concentrators for their support, guidance and feedback throughout the past year. This research was funded in part by the Harvard Undergraduate Science Research Program. !iii Abstract The subject of this work is the compositions of asteroids and meteorites. Studies of the composition of small Solar System bodies are fundamental to theories of planet formation. -
