Hyades Gaia EDR3 color–magnitude diagram. Left: Current cluster members together with Parsec (Bressan et al. 2012) isochrones in purple (600–800 Myr, left to right) for a slightly metal-rich cluster (z = 0.024) with no reddening. Open circles are known variable or double stars (Perryman et al. 1998); these were not considered in deciding the age of the cluster, which we estimate at 675 ± 72 Myr. Carbon–oxygen WD cooling sequences (Bédard et al. 2020) shown in red are for 0.6–0.8 and 1.3 M _⊙ (right to left). Right: The same but for stars kinematically consistent with having escaped the Hyades cluster. The candidate ultramassive WD1 is plotted in green, and WD2 and WD3 are in blue.
