An Optical Study of Young Stellar Clusters
... The star formation process determines the conversion of gas to stars, and the outcome are stars with a range of masses. The distribution of the stellar masses in a given volume of space in a stellar system at the time of their formation is known as the Initial Mass Function (IMF) of the system (Salp ...

Circumstellar Material in Young Stellar Objects
... angular momentum will be unable to fall directly onto the central star, and will instead accumulate in a rotating disk. The star can only accrete this material if the disk can shed angular momentum; as the mass moves inwards, the angular momentum has to move outwards and be stored in larger rotating ...

Abstract Title of Dissertation: BLACK HOLE DYNAMICS AND GRAVITATIONAL RADIATION IN GALACTIC NUCLEI
... mergers, and ionizations are all likely outcomes for binaries near the galactic center. Tidally separated binaries will contribute to the LISA detection rate, and mergers will produce ∼tens of events per year for Advanced LIGO. We show, therefore, that galactic nuclei are promising hosts of gravitat ...
