The Low-Mass Stars in Starburst Clusters
If star formation depends strongly on the global properties of the environment in which they form, the slope of the IMF as well as the upper and lower mass cut-offs would be expected to vary significantly between violent starbursts and more quiescent star forming regions. To test this hypothesis we observed the stellar content of the two closest massive star forming regions, 30 Doradus and NGC ...
متن کاملLow Velocity Ionized Winds from Regions Around Young O Stars
We have observed seven ultracompact H II regions in hydrogen recombination lines in the millimeter band. Toward four of these regions, there is a high velocity (full width to half maximum 60–80 km s) component in the line profiles. The high velocity gas accounts for 35%–70% of the emission measure within the beam. We compare these objects to an additional seven similar sources we have found in ...
متن کاملLow Energy X-ray Emission from Young Isolated Neutron Stars
A young neutron star with large spin-down power is expected to be closely surrounded by an e pair plasma maintained by the conversion of γ-rays associated with the star’s polar-cap and/or outer-gap accelerators. Cyclotron-resonance scattering by the e and e within several radii of such neutron stars prevents direct observations of thermal X-rays from the stellar surface. Estimates are presented...
متن کاملStellar Collisions in Young Clusters: Formation of (Very) Massive Stars?
In young star clusters, the density can be high enough and the velocity dispersion low enough for stars to collide and merge with a significant probability. This has been suggested as a possible way to build up the highmass portion of the stellar mass function and as a mechanism leading to the formation of one or two very massive stars (M∗ > 150M⊙) through a collisional runaway. I quickly revie...
متن کاملBinary Stars in Young Clusters – a Theoretical Perspective
The preponderance of binary systems in all known stellar populations makes them exciting dynamical agents for research on topics as varied as star formation, star-cluster dynamics and the interiors of young and old stars. Today we know that the Galactic-field binary population is probably a dynamically evolved version of the Taurus–Auriga pre-main sequence population, and that the initial distr...
