Abstract / Description:We developed a method to identify planetary
nebula (PN) candidates in imaging data of the
Sloan Digital Sky Survey (SDSS). This method
exploits the SDSS' five-band sampling of emission
lines in PN spectra, which results in a color
signature distinct from that of other sources
and can be applied to galaxies where PNe appear
as point sources. We tested this method with
SDSS data of M31. In areas searched by previous
authors, we were able to recover more than 3/4 of
the earlier known PNe, with incompleteness
caused largely by crowding effects. We then
extended this search to the full area of M31's
halo and disk sampled by the SDSS. We will
present the method and early results from this
project.
