Internal Rotation of Subdwarf B Stars: Limiting Cases and Asteroseismological Consequences
Internal Rotation of Subdwarf B Stars: Limiting Cases and Asteroseismological Consequences
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 10 km s-1), while hotter HB stars (those with Teff in excess of 11,000 K) typically show much smaller rotation velocities of 8 …
