Stars of type MS with evidence of white dwarf companions
Abstract
A report is presented on preliminary results of a search for white dwarf companions of MS-type stars. The overendowments of these stars in typical s-process nuclides suggests that they, like the Ba II stars, may owe their peculiar compositions to earlier mass transfer. Short-wavelength IUE spectra show striking emission line variability in HD 35155, HD 61913, and 4 Ori. HD 35155 and 4 Ori show evidence of white dwarf companions.
