NGC 1514 is a very dim nebula towards the constellation of
Taurus. It is characterized by a very dim, smooth outer shell
with a much brighter inner shell and bright blobs. Measurements of
the gas near center indicate that it is expanding outwardly at
25 kilometers per second. The morphology of this nebula is
currently thought to be determined by a binary star (instead of
a single star) in the center. Indeed, based on the likely masses
of the progenitor stars (and possible separation) astronomers
estimate these stars would orbit each other with a period of 4 to 9 days.
If there are two stars at the heart of this nebula- the more massive
one, which eventually shed its outer envelope, was probably 3-4 times
as massive as our Sun.
