Rotation Velocities of DA White Dwarfs with Convective Atmospheres

Original paper can be found at: http://www.astrosociety.org/pubs/cs/328.html Copyright ASPThe sharp H® NLTE line cores of hydrogen rich (DA) white dwarfs allow their projected rotational velocities to be determined. High resolution optical spectra of 22 stars obtained with the Keck I telescope are matched by synthetic spectra computed from a grid of NLTE model atmospheres. We concentrate preferentially on hydrogen-rich white dwarfs with convective atmospheres, i.e. with Te®
