Hot UV-bright stars of galactic globular clusters
S. Moehler, W. B. Landsman, T. Lanz +1
We have performed a census of the UV-bright population in 78 globular clusters using wide-field UV telescopes. This population includes a variety of phases of post-horizontal branc…
Properties of Galactic early-type O-supergiants: A combined FUV-UV and optical analysis
J. -C. Bouret, D. J. Hillier, T. Lanz +1
We aim to constrain the properties and evolutionary status of early and mid-spectral type supergiants (from O4 to O7.5). These posses the highest mass-loss rates among the O stars,…
The Origin of Hot Subluminous Horizontal-Branch Stars in Omega Centauri and NGC 2808
Allen V. Sweigart, Thomas M. Brown, Thierry Lanz +2
Hot subluminous stars lying up to 0.7 mag below the extreme horizontal branch (EHB) are found in the UV color-magnitude diagrams of omega Cen and NGC 2808. Such stars are unexplain…
Flash Mixing on the White Dwarf Cooling Curve: Understanding Hot Horizontal Branch Anomalies in NGC 2808
Thomas M. Brown, Allen V. Sweigart, Thierry Lanz +2
We present a UV CMD spanning the hot horizontal branch (HB), blue straggler, and white dwarf populations of the globular cluster NGC 2808. These data were obtained with the Space T…
