Activity and Kinematics of Cool and Ultracool Dwarfs
, 2012 Thesis (Ph.D.)--University of Washington, 2012The ages of cool and ultracool dwarfs are particularly important. For cool M dwarfs, accurate ages combined with their ubiquity in the stellar disk could lead to a new level of precision in age dating the ...

Observational studies of key stages in stellar evolution
This thesis presents observational investigations into three poorly-understood, but key stages in stellar evolution. Stars undergoing the post T Tauri phase - which lies between the well-studied T Tauri stage of disc accretion and the arrival onto the ...
