Oligarchic planetesimal accretion and giant planet formation
A. Fortier, O. G. Benvenuto, A. Brunini
Aims. In the context of the core instability model, we present calculations of in situ giant planet formation. The oligarchic growth regime of solid protoplanets is the model adopt…
The evolutionary status of the white dwarf companion of the binary pulsar PSR J1713+0747
O. G. Benvenuto, R. D. Rohrmann, M. A. De Vito
Splaver and coworkers have measured the masses of the white dwarf and the neutron star components of the PSR J1713+0747 binary system pair by Shapiro Delay. We attempt to find the…
The Formation of a Helium White Dwarf in Close Binary System with Diffusion
O. G. Benvenuto, M. A. De Vito
We study the evolution of a system composed by a 1.4 \msun neutron star and a normal, solar composition star of 2 \msun in orbit with a period of 1 day. Calculations were performed…
A Code for Stellar Binary Evolution and its Application to the Formation of Helium White Dwarfs
O. G. Benvenuto, M. A. De Vito
We present a numerical code intended for calculating stellar evolution in close binary systems. In doing so, we consider that mass transfer episodes occur when the stellar size ove…
Evolution and colours of helium-core white dwarf stars: the case of low metallicity progenitors
A. M. Serenelli, L. G. Althaus, R. D. Rohrmann +1
The present work is designed to explore the evolution of helium-core white dwarf (HeWD) stars for the case of metallicities much lower than the solar one (Z=0.001 and Z=0.0002). Ev…
Improved synthetic spectra of helium-core white dwarf stars
R. D. Rohrmann, A. M. Serenelli, L. G. Althaus +1
We examine the emergent fluxes from helium-core white dwarfs following their evolution from the end of pre-white dwarf stages down to advanced cooling stages. For this purpose, we…
