Hot stars in globular clusters: a spectroscopist's view. (Invited review).


Abstract (from CDS):

Globular clusters are ideal laboratories to study the evolution of low-mass stars. In this work we concentrate on three types of hot stars observed in globular clusters: horizontal branch stars, UV-bright stars, and white dwarfs. After providing some historical background and information on gaps and blue tails, we discuss extensively hot horizontal branch stars in metal-poor globular clusters, especially their abundance anomalies and the consequences for the determination of their atmospheric parameters and evolutionary status. Hot horizontal branch stars in metal-rich globular clusters are found to form a small but rather inhomogeneous group that cannot be explained by one evolutionary scenario. Hot UV-bright stars show a lack of classic post-asymptotic giant branch stars that may explain the lack of planetary nebulae in globular clusters. Finally, we discuss first results of spectroscopic observations of white dwarfs in globular clusters.
