Description
  • V tomto článku prezentujeme nová spektroskopická data s vysokým rozlišením v optické oblasti a také detailní popis infračervených pozorování. Z výsledků studia emisních čar v optické oblasti spektra a získaných hvězdných parametrů vyplývá, že hvězda CD-42°11721 může být hvězdou po hlavní posloupnosti. Dále jsme zjistili, že SED v optické a infračervené oblasti lépe vysvětluje model disku tvořeného hvězdným větrem, než sféricky symetrická obálka nebo tenký disk, což podporuje naši klasifikaci této hvězdy jako B[e] veleobra.

  • In this paper, we present new data gained from high-resolution optical spectroscopy and a detailed description of IR data of this star. We present a qualitative study of the numerous emission lines in our optical spectra and derive the stellar parameters with high precision and advocate that CD-42°11721 might be a post-main sequence object. We further found that the SED in the optical and infrared can best be fitted with an outflowing disk-forming wind scenario rather than with a spherical symmetric envelope or with a flared disc, supporting our tentative classification as a B[e] supergiant.
