| Abstract: |
Schilbach & Röser (2012) presented kinematic and photometric data for 37 white
dwarfs, including the 10 classical Hyades white dwarfs but also for a
number of white dwarfs that fulfill the same kinematic and photometric
criteria and are co-moving with the cluster. If these are indeed
former cluster members, the number of confirmed Hyades white dwarfs
could effectively be doubled. It so happens that most of these white
dwarfs, be they confirmed Hyades members or not, are included in the
sample of Gianninas et al. (2011). Consequently, we are in a position to
perform a spectroscopic analysis of these stars using the most recent
generation of model atmospheres coupled with high signal-to-noise
ratio observations of each star. Of particular interest is a new
determination of the mean mass of the Hyades white dwarfs which has
previously been shown to be higher than the mean mass of field white
dwarfs. |
