Geometrical Aspects of Venus Transit
Alberto C. Bertuola, C. Frajuca, N. S. Magalhães +1
We obtained two astronomical values, the Earth-Venus distance and Venus diameter, by means of a geometrical treatment of photos taken of Venus transit in June of 2012. Here we pres…
Omnidirectional Gravitational Wave Detector with a Laser-Interferometric Gravitational Compass
M. D. Maia, Ivan S. Ferreira, Claudio M. G. Sousa +2
Based on the Szekeres-Pirani gravitational compass we suggest the addition of a fourth, non-coplanar mass/mirror to the presently existing laser based gravitational wave observator…
Braking indices of pulsars obtained in the presence of an effective force
N. S. Magalhaes, A. S. Okada, C. Frajuca
Braking indices of pulsars present a scientific challenge as their theoretical calculation is still an open problem. In this paper we report results of a study regarding such calcu…
