Description
A spectrophotometric study of the peculiar open cluster Berkeley 87 is
presented; the measurements show that most of the members are young,
heavily reddened OB stars, but a few are much more evolved objects. Some
of these objects show in their spectra the presence of unusual
absorption lines, probably due to the local interstellar medium. The
stars n.3, n.9, n.15, and n.38 confirm the presence of intense emission
from the Balmer lines. The star n.78 (BC Cyg) clearly shows a late-type
spectrum, and the classification given in the literature and its
membership in Berk 87 is confirmed. A number of objects and especially
the stars n.14, n.15, and n.16 in the Rubner and Forbes (1982) list,
which lie very near the apparent cluster center and inside or very near
the error box of one of the strong IRAS sources, are discussed.
