Abstract:
We search the Hubble Space Telescope (HST) Advanced Camera for Surveys
and Wide Field Camera 3 broadband imaging data from the Panchromatic
Hubble Andromeda Treasury (PHAT) survey to identify detections of
cataloged planetary nebulae (PNs). Of the 711 PNs currently in the
literature within the PHAT footprint, we find 467 detected in the
broadband. For these 467, we are able to refine their astrometric
accuracy from ∼0.3'' to 0.05''. Using the resolution of the HST, we
are able to show that 152 objects currently in the catalogs are
definitively not PNs, and we show that 32 objects thought to be
extended in ground-based images are actually point-like and therefore
good PN candidates. We also find one PN candidate that is marginally
resolved. If this is a PN, it is up to 0.7 pc in diameter. With our
new photometric data, we develop a method of measuring the level of
excitation in individual PNs by comparing broadband and narrowband
imaging and describe the effects of excitation on a PN's photometric
signature. Using the photometric properties of the known PNs in the
PHAT catalogs, we search for more PNs, but do not find any new
candidates, suggesting that ground-based emission-line surveys are
complete in the PHAT footprint to F475W ≃ 24.
Description:
The Panchromatic Hubble Andromeda Treasury (PHAT) is a Hubble Space
Telescope (HST) multi-cycle imaging survey covering roughly one-third
of M31's star-forming disk out to 20 kpc (Dalcanton et al.
2012ApJS..200...18D 2012ApJS..200...18D). Observations were made with the HST using the
Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3), with
six filters spanning the UV (WFC3/UVIS F275W and F336W), the optical
(ACS/WFC F475W and F814W), and the NIR (WFC3/IR F110W and F160W).
