NGC 6337, the Ghostly Cheerio or Cheerio Nebula, is a toroidal planetary nebula in the constellation Scorpius. It appears as a ring-shaped (annular) transparent nebula resembling a piece of the breakfast cereal Cheerios, hence the name.

2009年5月8日 · NGC 6337 is a member of the rare group of planetary nebulae where a close binary nucleus has been identified. The nebula's morphology and emission line profiles are both unusual, particularly the latter.

In this work, we explore in detail the kinematic behavior and morphological structure of NGC 6337, a nebula where convincing evidence of the presence of a close binary nucleus exists.

1999年12月22日 · We have obtained narrow-band images and high-resolution spectra of the planetary nebulae NGC 6337, He 2-186, and K 4-47, with the aim of investigating the relation between their main morphological components and several low …

NGC 6337 is a small, bipolar planetary nebula (PNe), also known as the Cheerio Nebula, in the constellation of Scorpius at about 5,200 light years distant. It is situated within a field of backround hydrogen nebulosity. Planetary nebula arise from the evolution of smaller stars (0.8 – 8 solar masses) that end up as a white dwarf.

NGC 6337 is a member of the rare group of planetary nebulae where a close binary nucleus has been identified. The nebula's morphology and emission line profiles are both unusual, particularly the latter.

The relation between Zanstra temperature and morphology in planetary nebulaeWe have created a master list of Zanstra temperatures for 373 galacticplanetary nebulae based upon a compilation of 1575 values taken from thepublished literature. These are used to evaluate mean trends intemperature for differing nebular morphologies. Among the most prominentresults of this analysis is the tendency ...

NGC 6337 is a Planetary Nebula located in the constellation of Scorpius in the southern hemisphere. NGC 6337 is called NGC 6337 in the New General Catalogue (NGC). This …
