An accretion disk is a colossal whirlpool of gas and dust that gathers around a black hole or a neutron star like cotton candy as it pulls in material from a nearby star. As the disk spins, it whips u...
SN 2008jb: A "Lost" Core-Collapse Supernova in a Star-Forming Dwarf Galaxy at ~10 Mpc
SN 2008jb Core-Collapse Supernova Star-Forming Dwarf Galaxy
2011/10/19
We present the discovery and follow-up observations of SN 2008jb, a core-collapse supernova in the dwarf irregular galaxy ESO 302-14 at 9.6 Mpc. This transient was missed by galaxy-targeted surveys an...
A modified star formation law as a solution to open problems in galaxy evolution
galaxies: evolution – galaxies: formation – galaxies: stellar content –galaxies: haloes
2011/10/13
In order to reproduce the low mass end of the stellar mass function, most current models of galaxy evolution invoke very efficient supernova feedback. This solution seems to suffer from several shortc...

BROWN DWARF ACCRETION：NONCONVENTIONAL STAR FORMATION OVER VERY LONG TIMESCALES
Stars low-mass,brown dwarfs-Galaxy evolution-ISM general
2009/2/23
We investigate the process of accretion of interstellar gas by the
Galactic population of brown dwarfs over very long timescales typical for physical
eschatology. In particular, we use the classical...
