I finally finished an object. I started capturing this back in November. My lack in posting anything isn't do to me undergoing cancer treatment, rather a seriously horrible winter with almost no clear skies here in Michigan all winter long. The worse winter ever since I started astrophotography back in 2016.
Years ago when capturing the Heart Nebula in a more wide field set up, I started to get curious about a small object just above the Heart Nebula when combing through my data. I wanted to go deeper with a much tighter field of view with a different telescope to see what I could resolve and finally did so. It's pretty tiny even in with this field of view. I found the structure to be way more interesting when processing it with this new data set.
WeBo 1 (PN G135.6+01.0), a previously unrecognized planetary nebula with a remarkable thin-ring morphology, was discovered serendipitously on Digitized Sky Survey images. The central star is found to be a late-type giant with overabundances of carbon and s-process elements. The giant is chromospherically active and photometrically variable, with a probable period of 4.7 days; this suggests that the star is spotted, and that 4.7 days is its rotation period. It is proposed a scenario in which one component of a binary system became an asymptotic giant branch (AGB) star with a dense stellar wind enriched in C and s-process elements; a portion of the wind was accreted by the companion, contaminating its atmosphere and spinning up its rotation. The AGB star has now become a hot subdwarf, leaving the optical companion as a freshly contaminated barium star inside an ionized planetary nebula.
