IRAS 16455-3455 and IRAS 15154-5258 : two new southern planetary nebulae.
Abstract
The identification of two new southern planetary nebulae, IRAS 16455-3455 and IRAS 15154-5258, via low resolution spectroscopy, is reported. IRAS 16455-3455 is a high excitation planetary nebula with an extension of 9 arcsec, m(V) = 8.95 and E(B-V) = 1.21. Chemical abundances in this nebula are similar to the mean values for planetaries in the Galaxy. IRAS 15154-5258 is a hydrogen-poor nebula with a high infrared excess. The central star has a WC4 Wolf-Rayet spectrum.
