Discovery of a hot, interactive companion to the S star HD 35155

摘要: During an IUE investigation of the chromospheres S stars, we detected strong emission lines such ions as C IV and Si excess continuous in SWP exposure HD 35155 (S3,2).7hese indicate a hot gas with state ionization exceeding that found recently studied Ba star systems Zeta Cap 56 Peg, both which have white dwarf companions. observations 7 months later showed continuum had decreased by about 0.5 mag. 15–50%, high excitation decreasing most rapidly.
