O Type and Other Hot Binaries: Current Statistics of the USNO Database; Journal article

摘要

The first speckle survey of O stars (Mason et al. 1998) conducted on NOAO 4-m telescopes in 1994-6 had success far in excess of our expectations. In addition to the conclusions in the multiplicity analysis, many of the new systems which were first resolved in this paper have very significant astrophysical interest. This updates the statistics from 1998 based on new results from the double star catalogs maintained at the U.S. Naval Observatory.
