Galaxy Disks
The disks of disk galaxies contain a substantial fraction of their baryonic matter and angular momentum, and much of the evolutionary activity in these galaxies, such as the formation of stars, spiral arms, bars and rings, and the various forms of secular evolution, takes place in their disks. The formation and evolution of galactic disks are therefore particularly important for understanding h...
متن کاملTidal thickening of galaxy disks
We have studied a sample of 24 edge-on interacting galaxies and compared them to edge-on isolated galaxies, to investigate the effects of tidal interaction on disk thickening. We found that the ratio h/z0 of the radial exponential scalelength h to the scale height z0 is about twice smaller for interacting galaxies. This is found to be due both to a thickening of the plane, and to a radial strip...
متن کاملThe Formation of Galaxy Disks
Galaxy disk formation must incorporate the multiphase nature of the interstellar medium. The resulting two-phase structure is generated and maintained by gravitational instability and supernova energy input, which yield a source of turbulent viscosity that is able to effectively compete in the protodisk phase with early angular momentum loss of the baryonic component via dynamical friction in t...
متن کاملResonance Trapping in Protoplanetary Disks
Mean-motion resonances (MMRs) are likely to play an important role both during and after the lifetime of the protostellar gas disk. We study the dynamical evolution and stability of planetary systems containing two initially circular giant planets near 2:1 resonance and closer. We find that in addition to the 2:1, planets can capture into the 5:3 and 3:2. We use direct numerical integrations of...
