We found about 108 PNe detected by GALEX in near-UV (NUV) and also in far-UV (FUV) for 28 PNe considering a 3σ surface brightness level above the background. Of the PNe, 57 are elliptical, 41 are circular and rest 10 are bipolar in NUV. The emission lines contributing to GALEX FUV flux are strong O V, C IV, and He II while the emission line contributing to the NUV flux are C III] and He II. We have determined their sizes and structures in UV and compared the same with the data available in other wavelengths. |
