From KenCroswell.com:<br /><br /> An ultramassive white dwarf in Eridanus may have escaped from the Pleiades star cluster, say astronomers in England. If so, the lost Pleiad was once a bright blue star that outshone all the current cluster members. The discovery implies that the white dwarf evolved from a single star, contradicting theories that say ultramassive white dwarfs form only from the merger of two lesser white dwarfs.

Hi there.<br /><br />I am not surprised. Alpha Aurigae / Capella, is almost certainly ejected from the Hyades (shares same proper motion & is the same age as the cluster, but is slightly slower moving).<br /><br />Alpha Canis Minoris / Polaris may have been ejected from the Alpa Persei / Mirphak association. Beta Aurigae / Menkarlinan, is part of the Ursa Major moving group, along with many others (Sirius may be a member too).<br /><br />Our Sun may be part of as yet an unidenetifeid group.<br /><br />Welcome to SDC. Brilliant first point.<br /><br />Andrew Brown. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.
