Long-Term Optical Monitoring of Eta Carinae. Multiband light curves for a complete orbital period
E. Fernandez-Lajus, C. Farina, A. F. Torres +8
The periodicity of 5.5 years for some observational events occurring in Eta Carinae manifests itself across a large wavelength range and has been associated with its binary nature.…
Gemini/GMOS search of massive binaries in the ionizing cluster of 30 Dor
Guillermo Bosch, Elena Terlevich, Roberto Terlevich
If binaries are common among massive stars, it will have important consequences for the derivation of fundamental properties like the cluster age, IMF and dynamical mass. Making us…
On the origin of white dwarfs with carbon-dominated atmospheres: the case of H1504+65
L. G. Althaus, A. H. Córsico, S. Torres +1
We explore different evolutionary scenarios to explain the helium deficiency observed in H1504+65, the most massive known PG1159 star. We concentrate mainly on the possibility that…
WMAP 5-year constraints on time variation of and in a detailed recombination scenario
Claudia G. Scóccola, Susana. J. Landau, Hector Vucetich
We study the role of fundamental constants in an updated recombination scenario. We focus on the time variation of the fine structure constant, and the electron mass in the early U…
Modeling He-rich subdwarfs through the hot-flasher scenario (brief version)
M. M. Miller Bertolami, L. G. Althaus, K. Unglaub +1
We present 1D numerical simulations aimed at studying the hot-flasher scenario for the formation of He-rich subdwarf stars. Sequences were calculated for a wide range of metallicit…
Core instability models of giant planet accretion II: forming planetary systems
Yamila Miguel, Adrian Brunini
We develop a simple model for computing planetary formation based on the core instability model for the gas accretion and the oligarchic growth regime for the accretion of the soli…
