The white-dwarf companions of 56 Persei and HR 3643.
LANDSMAN W., SIMON T. and BERGERON P.
Abstract (from CDS):
Prompted by our detection of a white dwarf companion of a luminous F star, we have examined the IUE archives to assess the upper limits on possible white dwarf companions to Cepheids. The detection of a Cepheid–white dwarf binary would provide important insights concerning the most massive progenitors of white dwarfs. Only for the cases of alpha UMi and Beta Dor are existing IUE spectra of Cepheids sufficiently deep to rule out the presence of a white dwarf companion.
