| Abstract: |
We investigated the dust and elemental abundances of the
planetary nebula M1-11 based on the multiwavelength data. We calculated
elemental abundances using recombination lines and
collisionally excited lines. The C/O gas abundance ratio suggests that
M1-11 is an O-rich PN, while C-rich dust features are seen in the
AKARI/IRC and Spitzer/IRS spectra. The detection of the
fullerenes C60 17.3/18.9 μm is the first time for this PN.
We constructed a spectral energy distribution model to derive
properties of the central star and the ionized nebula and estimate
the dust mass. |
