- Eric (novel) (wikipedia.org)
Eric, stylized as Faust Eric, is the ninth Discworld novel by Terry Pratchett. It was originally published in 1990 as a “Discworld story”, in a larger format than the other novels and illustrated by Josh Kirby. It was later reissued as a normal paperback without any illustrations, and in some cases, with the title given on the cover and title pages simply as Eric. (The page headers, however, continued to alternate between Faust and Eric.)
- 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.
