摘要
We have studied archival, short-wavelength, low resolution IUE spectra of Hyades F stars in an effort to detect white dwarf companions, which can give us information about the IMF for the Hyades cluster. Weidemann et al. pointed out that we have not detected the expected number of white dwarfs in the Hyades. They suspected that the missing white dwarfs have evaporated from the cluster. This cannot have happened with white dwarf companions to A and F stars. We estimate that for the 27 observed Hyades F stars we should have seen 3 white dwarfs while we found none. © 1995 American Astronomical Society.
