Brown Dwarfs as Ejected Stellar Embryos: Observational Perspectives
Bo Reipurth, Cathie Clarke
We discuss a scenario in which brown dwarfs are formed like stars, except that their full collapse phases are interrupted through dynamical interactions in small multiple systems,…
Testing the Unified Model with an Infrared Selected Sample of Seyferts
H. R. Schmitt, J. S. Ulvestad, R. R. J. Antonucci +3
We present a series of statistical tests using homogeneous data and measurements for a sample of Seyfert galaxies. These galaxies were selected from mostly isotropic properties, th…
A Dynamical Origin for Brown Dwarfs
Bo Reipurth, Cathie Clarke, Eduardo Delgado-Donate
Brown dwarfs may have such low masses because they are prematurely ejected from small unstable multiple systems, while the members are still actively building up their masses. We d…
Mechanical Feedback: From stellar wind bubbles to starbursts
M. S. Oey, C. J. Clarke, P. Massey
The current understanding of mechanical feedback is reviewed by evaluating the standard, adiabatic model for shell formation and evolution. This model is relevant to phenomena rang…
The Formation of Stellar Clusters
Cathie J. Clarke, Ian A. Bonnell, Lynne A. Hillenbrand
We review recent work that investigates the formation of stellar clusters, ranging in scale from globular clusters through open clusters to the small scale aggregates of stars obse…
The Size Distribution of Superbubbles in the Interstellar Medium
M. S. Oey, C. J. Clarke
We use the standard, adiabatic shell evolution to predict the size distribution N(R) for populations of SN-driven superbubbles in a uniform ISM. We derive N(R) for simple cases of…
