Ap and Bp stars are peculiar stars (hence the “p”) of types A and B which show overabundances of some metals, such as strontium, chromium and europium; in addition, larger overabundances are often seen in praseodymium and neodymium. These stars have a much slower rotation than normal for A and B type stars, although some exhibit rotation velocities up to about 100 kilometers per second.

Famous quotes containing the word stars:
“The sumptuous age of stars and images is reduced to a few artificial tornado effects, pathetic fake buildings, and childish tricks which the crowd pretends to be taken in by to avoid feeling too disappointed. Ghost towns, ghost people. The whole place has the same air of obsolescence about it as Sunset or Hollywood Boulevard.”
—Jean Baudrillard (b. 1929)
