Abstract:
We present the Planetary Enriched White Dwarf Database (PEWDD), a
collection of published photospheric abundances of white dwarfs
accreting planetary debris alongside additional information relevant
to metal-enrichment and the presence of infrared excesses, emission
lines, and binary companions. At the time of publishing, PEWDD
contains information on 1739 white dwarfs and will be kept up to date
with information from new publications. A total of 24 photospheric
metals are recorded and are linked to accretion of exo-planetary
material. The overall properties of metal-enriched white dwarfs are
severely affected by observational selection effects. In particular,
we find that the metals that are detectable strongly correlate with
the effective temperature. By considering metal-enriched white dwarfs
that have abundances measured by different methods, we find a spread
that is comparable with the often-quoted ad hoc estimated abundance
uncertainties, namely ≃0.1-0.2dex. We draw attention to a
dichotomy in the median accretion rates for metal-enriched H- and
He-dominated white dwarfs, with dMacc,H/dt=7.7x107g/s and
dMacc,He/dt=8.7x108g/s, when extrapolating bulk compositions
from bulk Earth Ca abundance. We identified 40 metal-enriched white
dwarfs in binary systems and find evidence that enrichment is
suppressed by binary companions within 200au.
Description:
PEWDD contains data on the properties of white dwarf accreting
planetary material, most importantly the metal abundances and
accretion rates. Use of PEWDD will allow the compositions of
extra-solar objects to be investigated anc compared. This information
is taken from the literature and will be continually updated.
