Cordas cósmicas girantes na gravitação de Brans-Dicke
(Universidade Estadual Paulista (Unesp), 2018-02-23)
A partir da teoria da gravitação de Brans-Dicke, são obtidas soluções exatas para as cordas cósmicas girantes. As soluções são para cordas retas, que preservam a simetria de Lorentz ao longo do eixo longitudinal de simetria, ...
MEASURING SIZES OF ULTRA-FAINT DWARF GALAXIES
(IOP PUBLISHING LTD, 2012-02-01)
The discovery of ultra-faint dwarf (UFD) galaxies in the halo of the Milky Way extends the faint end of the galaxy luminosity function to a few hundred solar luminosities. This extremely low luminosity regime poses a ...
Parameters for SMC clusters from CMD modeling
(International Astronomical UnionFlorianópolis, 2013)
Stellar clusters in the Small Magellanic Cloud are
fundamental pieces to study the chemical and dynamical
evolution of this neighbouring dwarf galaxy,
enabling inspection of a large period covering ∼10
Gyr. The main ...
A faint type of supernova from a white dwarf with a helium-rich companion
(2010)
Supernovae are thought to arise from two different physical processes. The cores of massive, short-lived stars undergo gravitational core collapse and typically eject a few solar masses during their explosion. These are ...
