Title: Using White Dwarfs To Constrain Angular Momentum Transport In Stellar Evolution

PI: Provencal, Judith - University Of Delaware

Type: SMALL

Summary: This proposal outlines a comprehensive study of white dwarf (WD) rotation with an observational emphasis on improving the sample of WDS with direct detection of rotation rates. The science impact includes 1) providing boundary conditions for mechanisms of angular momentum transport during the final stages of stellar evolution, 2) exploring the distribution of WD rotation rates for evidence of multiple origin channels for different WD populations, 3) exploring the rotation rates of WDs as a function of temperature/mass, 4) calibrating asteroseismic rotation rates for WD pulsators, 5) examining WD pulsators for evidence of differential rotation and 6) providing a connection between surface rotation and asteroseismic rotation rates (core, surface, and interior rotation) for WD pulsators.
