Ap and BP Stars

Ap and Bp stars are peculiar stars (hence the ā€œpā€) 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:

    “They cannot scare me with their empty spaces
    Between stars—on stars where no human race is.
    I have it in me so much nearer home
    To scare myself with my own desert places.”
    —Robert Frost (1874–1963)
