| Abstract: |
We present new Hubble Space Telescope observations of boron abundances in 26 early-B
stars with vsini between 50 and 230 km s-1. This is the first sample that extends to
sufficiently high projected rotational velocities to allow critical comparison with stellar evolution models
that include estimates of rotationally driven mixing. The implications of our results for
these models are discussed. |
