Internal rotation of subdwarf B stars: limiting cases and asteroseismological consequences
Steven D. Kawaler, Shelbi R. Hostler
Observations of the rotation rates of horizontal branch (HB) stars show puzzling systematics. In particular, cooler HB stars often show rapid rotation (with velocities in excess of…

Pulsating sdB Stars: A New Approach to Probing their Interiors
Steven D. Kawaler, Shelbi R. Hostler
Horizontal branch stars should show significant differential rotation with depth. Models that assume systematic angular momentum exchange in the convective envelope and local conse…
