Gravitational collapse of magnetized clouds. I. Ideal MHD accretion flow
D. Galli, S. Lizano, F. H. Shu +1
We study the self-similar collapse of an isothermal magnetized rotating cloud in the ideal magnetohydrodynamic (MHD) regime. In the limit of small distance from the accreting proto…
Deuterium chemistry in the primordial gas
D. Galli, F. Palla
We review and update some aspects of deuterium chemistry in the post-recombination Universe with particular emphasis on the formation and destruction of HD. We examine in detail th…
The 12C/13C ratio in the Planetary Nebula NGC3242 from Hubble Space Telescope STIS observations
F. Palla, D. Galli, A. Marconi +2
We present high resolution HST ultraviolet spectroscopy of NGC3242, the only planetary nebula with a measured abundance of 3He. The Space Telescope Imaging Spectrograph (STIS) has…
Galactic chemical evolution of heavy elements: from Barium to Europium
C. Travaglio, D. Galli, R. Gallino +3
We follow the chemical evolution of the Galaxy for elements from Ba to Eu, using an evolutionary model suitable to reproduce a large set of Galactic (local and non local) and extra…
The Chemistry of the Early Universe
D. Galli, F. Palla
The process of molecule formation in the primordial gas is considered in the framework of Friedmann cosmological models from redshift z=1e4 to z=0. First, a comprehensive analysis…
Lithium hydride in the early universe and in protogalactic clouds
E. Bougleux, D. Galli
We examine the processes of formation and destruction of LiH molecules in the primordial gas at temperatures T \leq 5000 K in the framework of standard Friedmann cosmological model…
