Planetary nebula K1-9.

KONDRATYEVA L.N. and DENISYUK E.K.

Abstract (from CDS):

The object K1-9 with strong [NII] emission lines was included in the Perek and Kohoutek Catalogue of Planetary Nebulae, but later it was considered to be an HII region. Our results show that in addition to the low-excitation emissions there are HeII and [OIII] emission lines in its spectrum, and the effective temperature of the central star is more than 54000K. Thus we conclude that K1-9 is indeed a planetary nebula. Distribution of [OIII] and [NII] emission lines reflect a ring-like structure with a clear minimum in the centre of the nebula. Hydrogen lines almost fail to show the central gap. K1-9 has the backward proper motion with systemic velocity RV=60.2km/s. The central hydrogen component moves relative to the nebula with a pecular velocity of about -50km/s.
