- OB association (Wikipedia)
Young associations will contain 10 to 100 massive stars of spectral class O and B, and are known as OB associations. In addition, these associations also contain hundreds or thousands of low- and intermediate-mass stars. Association members are believed to form within the same small volume inside a giant molecular cloud. Once the surrounding dust and gas is blown away, the remaining stars become unbound and begin to drift apart.
- Beid (stars.astro.illinois.edu)
BEID (Omicron-1 Eridani). In the middle of the first southerly turning of Eridanus (the River) lie a seeming pair of fourth magnitude stars, Beid and Keid, which Bayer placed far down in the Greek alphabet as Omicron-1 and Omicron-2.
