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.
