This thesis seeks to explain the nature of line emission observed in young stellar objects, and to use the lines as diagnostics of the accretion process that is central to star formation. We maintain ...

In order to understand which process (e.g. galactic winds, cold accretion) is responsible for the cool (T~10^4 K) halo gas around galaxies, we embarked on a program to study the star-formation propert...

We present evidence that the incidence of active galactic nuclei (AGN) and the distribution of their accretion rates do not depend on the stellar masses of their host galaxies, contrary to previous st...
Nonradial and nonpolytropic astrophysical outflows IX. Modeling T Tauri jets with a low mass-accretion rate

Context: A large sample of T Tauri stars exhibits optical jets, approximately half of which rotate slowly, only at ten per cent of their breakup velocity. The disk-locking mechanism has been shown to ...
Considerations on the accretion of Uranus and Neptune by mutual collisions of planetary embryos in the vicinity of Jupiter and Saturn
planetary systems – planets and satellites: formation – planets and satellites: individual: Uranus, Neptune – protoplanetary disks

2011/10/8
Modeling the formation of Uranus and Neptune is a long-lasting problem in planetary science. Due to the gas-drag, collisional damping, and resonant shepherding, the planetary embryos repel the planete...
