description Abell 65 Overview
Abell 65 is a faint bipolar planetary nebula located in the constellation Sagittarius. It is highly notable for its elongated, ring-like structure and for containing a close binary central star system at its core. The two stars in this system orbit each other with an exceptionally short period of approximately 1.15 days, which is unusually fast for a post-common-envelope binary. Studying this nebula provides astronomers with valuable insights into the effects of binary star evolution on planetary nebula formation.
help Abell 65 FAQ
What kind of object is Abell 65?
Abell 65 is a faint planetary nebula in the constellation Sagittarius. It consists of glowing gas expelled by a dying star, not a galaxy or a star-forming cloud.
Why does Abell 65 have a long, bipolar shape?
Its elongated, ring-like structure is associated with the close binary system at its center. Interactions between the two central stars are thought to influence the shape of the expelled gas.
Does Abell 65 have one central star or two?
Abell 65 contains a close binary central star system, meaning two stars orbit one another at its core. That binary is one of the nebula's most notable features.
Can I see Abell 65 without a telescope?
It is considered a faint planetary nebula, so it is not an easy naked-eye target. Observers generally need a telescope and dark-sky conditions to search for Abell 65 in Sagittarius.
