ISO observations of the planetary nebula Lindsay 305 in the Small Magellanic Cloud
We present ISO (Infrared Space Observatory) observations of the planetary
nebula Lindsay 305 (L 305) in the Small Magellanic Cloud. L 305 is very
prominent in the ISOCAM frames at 6.75 and 11.5 m, although it is under
the detection limit at 4.5 m. The obtained spectral energy distribution
shows a strong mid-IR excess, which, depending on the amount of energy radiated
at wavelengths longer than 11.5 m, may be as large as . However, since an accurate estimate of the total nebular luminosity
is not available up to date, the evolutionary status of L 305 can not yet be
constrained precisely.Comment: 4 pages, 2 figures, to appear in the Publications of the Astronomical
