Title: Multiplicity Among Young Stars and Brown Dwarfs

Speaker: Dr. Ray Jayawardhana

Institute: University of Toronto

Location: ABB 102

Description:

Multiple systems are a common outcome and an important diagnostic of the star and brown dwarf formation processes. I will highlight some findings on the frequency and properties of multiple systems from on-going adaptive optics imaging and radial velocity surveys. I will also discuss what these surveys tell us about the formation of brown dwarfs both in isolation and as companions to stars, and describe observational attempts to investigate the effect of binary companions on circumstellar disk dissipation.
