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 ...
