Abstract:
New spatiokinematic observations were undertaken of the planetary
nebula NGC 1514 in the [O III] line at 5007Å using an imaging
Fabry-Perot spectrometer. Our results show an inner ellipsoidal shell
and polar blobs that do not conform to bipolar morphology. It is
argued that the nebula is a descendant of a common envelope binary
system the periodicity of which is estimated to be about 10 days, with
a progenitor mass of 4.5M☉.
Description:
The spatiokinematic observations on NGC 1514 were made using the PRL
Imaging Fabry-Perot Spectrometer at the f/13 Cassegrain focus of the
1.2m Gurushikhar infrared telescope, Mount Abu, India, during the
night of 1996 December 13.
