White dwarf-open cluster associations based on Gaia DR2
  Fundamental parameters and physical processes leading to the formation of
white dwarfs (WDs) may be constrained and refined by discovering WDs in open
clusters (OCs). Cluster membership can be utilized to establish the precise
distances, luminosities, ages, and progenitor masses of such WDs. We compile a
list of probable WDs that are OC members in order to facilitate WD studies that
are impractical or difficult to conduct for Galactic field WDs. We use recent
catalogs of WDs and OCs that are based on the second data release of the
\textit{Gaia} satellite mission (GDR2) to identify WDs that are OC members.
This crossmatch is facilitated by the astrometric and photometric data
contained in GDR2 and the derived catalogs. Assuming that most of the WD
members are of the DA type, we estimate the WD masses, cooling ages, and
progenitor masses. We have detected several new likely WD members and
reassessed the membership of the literature WDs that had been previously
associated with the studied OCs. Several of the recovered WDs fall into the
recently reported discontinuity in the initial-final mass relation (IFMR)
around $M_{i} \sim 2.0 M_{\odot}$, which allows for tighter constrains on the
IFMR in this regime.
