Search for envelopes of some stellar planetary nebulae, symbiotic stars and further emission-line objects.

KOHOUTEK L.

Abstract (from CDS):

At 17 emission-line objects, mainly PN, the seeing disc has been compared with that of some surrounding stars (CCD frames taken through B, V, R, [OIII] 5007Å and Hα filters). Nebulosities were found at: CPD-53o 8315 (0.5" in x-direction, 0.4" in y-direction), H 2-2 (0.3", 1.4") and CPD-56o 8032 (1.3", 1.3"). Further small nebulosities are possible at MWC 560, MWC 574, LS IV-12o 111 and HR Del, but they should be considered as rather uncertain. Besides, the known outer nebula at CPD-53o 8315 (2 condensations, 11.6" separation, PA=146o) was observed, and the author discovered a circular halo of 50'' around Hb 6 - both outer nebulosities visible in the light of Hα.
