Star Formation Modes in Low - Mass Disk Galaxies
Low-mass disk galaxies with well-organized structures are relatively common in low density regions of the nearby Universe. They display a wide range in levels of star formation activity, extending from sluggishly evolving 'superthin' disk systems to nearby starbursts. Investigations of this class of galaxy therefore provides opportunities to test and define models of galactic star formation pro...
متن کاملA Circumstellar Disk in a High-mass Star-forming Region
We present an edge-on Keplerian disk model to explain the main component of the 12.2 and 6.7 GHz methanol maser emission detected toward NGC 7538 IRS 1N. The brightness distribution and spectrum of the line of bright masers are successfully modeled with high amplification of background radio continuum emission along velocity-coherent paths through a maser disk. The bend seen in the position-vel...
متن کاملDisk Tides and Accretion Runaway
It is suggested that tidal interaction of an accreting planetary embryo with the gaseous pre-planetary disk may provide a mechanism to breach the so-called runway limit during the formation of the giant planet cores. The disk tidal torque converts a would-be shepherding obj ect into a “predator”, which can continue to cannibalize the planet.esirnal disk. This is more likely to occur in the gian...
متن کاملRunaway collisions in star clusters
We study the occurrence of physical collisions between stars in young and compact star cluster. The calculations are performed on the GRAPE-4 with the starlab software environment which include the dynamical evolution and the nuclear evolution of all stars and binaries. The selection of the initial conditions is based on existing and well observed star clusters, such as R136 in the 30 Doradus r...
متن کاملLow - Mass Runaway Stars from the Orion Trapezium Cluster
In the course of a search for common proper motion binaries in the Jones & Walker (JW) catalogue of proper motions in the Orion Nebula Cluster, we came across several faint stars with proper motions larger than one arcsecond per century and probabilities of membership P larger than 0.90. Such stars are interesting because they could be low-mass runaway stars recently accelerated by n-body inter...
