On the Evolution of Cosmological Type Ia Supernovae and the Gravitational Constant
E. Garcia-Berro, E. Gaztanaga, J. Isern +2
There are at least three ways in which a varying gravitational constant could affect the interpretation of the recent high-redhisft Type Ia supernovae results. If the local val…
Possibility of the detection of classical novae with the shield of the INTEGRAL-spectrometer SPI
P. Jean, J. Gomez-Gomar, M. Hernanz +7
The shield of the INTEGRAL spectrometer provides a large detection area with a wide field-of-view. Calculations have been performed to check whether the temporal analysis of the co…
Gamma-ray emission of classical novae and its detectability by INTEGRAL
M. Hernanz, J. Gomez-Gomar, J. Jose +2
A lot of information concerning the mechanism of nova explosions will be extracted from the possible future observations with INTEGRAL. In order to be prepared for this task, we ar…
Production of the LiBeB isotopes with time-dependent GCR fluxes
Carlos Abia, Ute Lisenfeld, Jordi Isern
It is well known that no time-independent galactic cosmic ray (GCR) flux model can account for the observed linear relationship of Be and B abundances with metallicity. In this con…
Monte Carlo simulations of the disk white dwarf population
E. Garcia-Berro, S. Torres, J. Isern +1
In order to understand the dynamical and chemical evolution of our Galaxy it is of fundamental importance to study the local neighborhood. White dwarf stars are ideal candidates to…
