Reconstructing the Pleiades with Gaia EDR3
  We search through an eight-million cubic-parsec volume surrounding the
Pleiades star cluster and the Sun to identify both the current and past members
of the Pleiades cluster within the Gaia EDR3 dataset. We find nearly 1,300
current cluster members and 289 former cluster candidates. Many of these
candidates lie well in front or behind the cluster from our point of view, so
formerly they were considered cluster members, but their parallaxes put them
more than 10 pc from the centre of the cluster today. Over the past 100 Myr we
estimate that the cluster has lost twenty percent of its mass including two
massive white dwarf stars and the $\alpha^2$ Canum Venaticorum-type variable
star, 41 Tau. All three white dwarfs associated with the cluster are massive
($1.01-1.06~\textrm{M}_\odot$) and have progenitors with main-sequence masses
of about six solar masses. Although we did not associate any giant stars with
the cluster, the cooling time of the oldest white dwarf of 60~Myr gives a firm
lower limit on the age of the cluster.
