Abstract:
We perform a deep survey of planetary nebulae (PNe) in the spiral
galaxy NGC 300 to construct its planetary nebula luminosity function
(PNLF). We aim to derive the distance using the PNLF and to probe the
characteristics of the most luminous PNe. We analyse 44 fields
observed with MUSE at the VLT, covering a total area of ∼11kpc2. We
find [OIII]5007 sources using the differential emission line filter
(DELF) technique. We identify PNe through spectral classification
using the aid of the BPT-diagram. The PNLF distance is derived using
the maximum likelihood estimation technique. For the more luminous
PNe, we also measure their extinction using the Balmer decrement. We
estimate the luminosity and effective temperature of the central stars
of the luminous PNe, based on estimates of the excitation class and
the assumption of optically thick nebulae. We identify 107 PNe and
derive a most-likely distance modulus (m-M)0=26.48+0.11-0.26
(d=1.98+0.10-0.23Mpc). We find that the PNe at the PNLF cut-off
exhibit relatively low extinction, with some high extinction cases
caused by local dust lanes. We present the lower limit luminosities
and effective temperatures of the central stars for some of the
brighter PNe. We also identify a few Type I PNe that come from a young
population with progenitor masses >2.5M☉, however do not
populate the PNLF cut-off. The spatial resolution and spectral
information of MUSE allow precise PN classification and photometry.
These capabilities also enable us to resolve possible contamination by
diffuse gas and dust, improving the accuracy of the PNLF distance to
NGC 300.
Description:
Catalogue of 107 planetary nebulae based on the observation of 44 MUSE
fields in NGC 300. For all of the planetary nebulae, the coordinates,
the [OIII]5007 magnitudes, and the selected line fluxes without
aperture correction (H-beta, [OIII]5007, H-alpha, [NII]6584,
[SII]6717, [SII]6731) are presented. For some of the planetary
nebulae, the extinction and the estimates of central star luminosity
and effective temperature are also given. Remarks on possible Type I
planetary nebula or the classification that relies only on [OIII]5007
detection are also noted.
