Abstract:
This paper examines, compares and plots optical, near- and
mid-infrared (MIR) photometric data for 605 planetary nebulae (PNe) in
the Large Magellanic Cloud (LMC). With the aid of multiwavelength
surveys such as the Spitzer legacy programme Surveying the
Agents of a Galaxy's Evolution, the Two Micron All Sky Survey and the
Magellanic Cloud Photometric Survey, plots have been constructed to
expose the relative contributions from molecular hydrogen, polycyclic
aromatic hydrocarbons, forbidden emission lines, warm dust continuum
and stellar emission at various bands. Besides identifying trends,
these plots have helped to reveal PN mimics including six previously
known PNe in the outer LMC which are re-classified as other object
types. Together with continuing follow-up optical observations, the
data have enabled a substantial reduction in the number of PNe
previously tagged as 'likely' and 'possible'. The total number of LMC
PNe is adjusted to 715 but with a greater degree of confidence in
regard to classification. In each colour-colour plot, the more highly
evolved LMC PNe are highlighted for comparison with younger, brighter
PNe. The faintest and most evolved PNe typically cluster in areas of
colour-colour space occupied by ordinary stars. Possible reasons for
the wide disparity in infrared colour-colour ratios, such as evolution
and dust composition, are presented for evaluation. A correlation is
found between the optical luminosity of PNe, emission-line ratios and
the MIR dust luminosity at various bands. Luminosity functions using
the four Infrared Array Camera and Multiband Imaging Photometer of
Spitzer (MIPS) [24] bands are directly compared, revealing an
increasing accumulation of PNe within the brightest two magnitudes at
longer wavelengths. A correlation is also found between the MIPS [24]
band and the [OIII] 5007 and Hβ fluxes.
Description:
Using the 2MASS 6x catalogue for the LMC (Cutri et al. 2003, Cat. II/246;
2012, Cat. VII/233), magnitudes were obtained for 274 PNe in J, 269 in
H and 263 in Ks.
To increase the number of detections available for comparison,
magnitudes were also obtained from the InfraRed Survey Facility (IRSF)
Magellanic Clouds Point Source Catalogue (Kato et al., 2007, Cat. II/288).
The 3.6, 4.5, 5.8 and 8um bands were obtained with the IRAC on board
Spitzer. This study used the archival data from the Spitzer legacy
programme SAGE (Meixner et al., 2006, Cat. J/AJ/132/2268) which mapped
the central 7x7deg2 area of the LMC.
The MIPS data were also obtained from both the Hora et al. (2008, Cat.
J/AJ/135/726) and Gruendl & Chu (2009, Cat. J/ApJS/184/172) studies.
