Estimativa de distância da região HII galáctica RCW 87
(Universidade Federal de Santa Maria, 2007-02-27)
In this work we present a espectrophotometric study and a photometric study in the filters B, V , R and I from the stars of the galactic H II region RCW 87 whose coordinates in the celestial equatorial system are α = 15 h ...
Catálogo de intensidades de linhas de emissão de regiões HII
(Universidade Federal de Santa Maria, 2007-02-27)
A catalog of relative emission-line intensities is presented. It contains data on 215 H II regions in the Galaxy, Magellanic Clouds and in others galaxies, all totaling 23 140 emission line intensities. We have determined ...
Anomalias de traço e radiação de Hawking
(Universidade Federal de Santa Maria, 2007-03-08)
In the present work we obtain the general form for the anomalous stress-energy tensor for static black holes with spherical symmetry, for the three quantum vacuum states of interest in black holes physics. The particular ...
Avanço do periastro e deflexão da luz no campo gravitacional de estrelas e buracos negros carregados e em rotação
(Universidade Federal de Santa Maria, 2007-03-08)
In the present study it is obtained analytic expressions to the periastron advance and light bending in the gravitational field of rotating and electrically charged black holes. First it is made a historical review emphasizing ...
Introdução ao método Monte Carlo: exemplos de aplicação
(Universidade Federal de Santa Maria, 2007-03-08)
In the present work, we study the Monte Carlo method in an introductory level. This method has been applied in models and systems whose results are known to compare with ours results. In the first part of this work, some ...
Desenvolvimento de um magnetômetro de torque
(Universidade Federal de Santa Maria, 2007-02-27)
In this work a torque magnetometer was developed for the study of the magnetic anisotropy on magnetic materials. The system which composes the torque magnetometer is constituted basically by a torsional pendulum with an ...
Implementação de um método de análise de imagens para integração da intensidade de raios X espalhados em uma câmera de Debye-Scherrer
