Presolar Grains from Novae

S. Amari, X. Gao, L. N. Nittler +4

We report the discovery of five SiC grains and one graphite grain isolated from the Murchison carbonaceous meteorite whose major-element isotopic compositions indicate an origin in…

The HI Content of Spirals. II. Gas Deficiency in Cluster Galaxies

Jose M. Solanes, Alberto Manrique, Carlos Garcia-Gomez +3

We derive the atomic hydrogen content for a total of 1900 spirals in the fields of eighteen nearby clusters. By comparing the HI deficiency distributions of the galaxies inside of…

The ages of very cool hydrogen-rich white dwarfs

M. Salaris, E. Garcia-Berro, M. Hernanz +2

The evolution of white dwarfs is essentially a cooling process that depends primarily on the energy stored in their degenerate cores and on the transparency of their envelopes. In…

Galactic 1.275 MeV emission from ONe novae and its detectability by INTEGRAL/SPI

P. Jean, M. Hernanz, J. Gomez-Gomar +1

Models of Galactic 1.275 MeV emission produced by the decay of the radionuclide Na have been computed. Several frequency-spatial distributions of novae have been investigate…

Thermonuclear Runaways on Accreting White Dwarfs: Models of Classical Novae Explosions

Margarita Hernanz, Jordi Jose

The mechanism of classical novae explosions is explained, together with some of their observational properties. The scarce but not null impact of novae in the chemical evolution of…
