PN G291.4-00.3: A new type I planetary nebula

In the vicinity of the southern hemisphere giant HII region NGC3603 we disc overed a new planetary nebula: PN G291.4-00.3 located at RA(J2000.0) =11(h) 14(m) 32.(s)1 +/- 0.(s)3, DECJ2000.0 = 61 degrees 00'02 " +/- 100. Monochr omatic images reveal a central ring-like structure accompanied by onsets of arc-like filaments which might outline a bipolar out ow. Analysis of the n ebula spectrum shows that helium and nitrogen are enriched, while oxygen, s ulphur and argon abundances seem to be solar. The central star must be hot (above 100 kK) and having a luminosity of more than 3000 L-circle dot. All evidence shows that PN G291.4-00.3 is a high-excitation, density bounded pl anetary nebula of the type I, coming from the high-mass end of the intermed iate mass stars.
