Late-Type Stars and Brown Dwarfs

Description: 

Over the last twelve years the continuing discovery and increasingly accurate characterization of brown dwarfs and extrasolar giant planets (EGPs) have created a new frontier in stellar and planetary astronomy. The development of accurate spectral diagnostics and the refinement of the theoretical models to describe these objects are among the most important challenges for the future. We are contributing to both of these goals through a combined theoretical and experimental program to obtain highly accurate profiles of alkali resonance lines broadened by collisions with molecular hydrogen and helium.
