The Visible Spectra of Three B-Stars - Pi-Ceti 36-LYNCIS 134-TAURII
Abstract
We present an identification list for the visible spectra of three B stars: π Cet (B7V), 36 Lyn B8 IIIp (?)),and 134 Tau (B9 IV). Equivalent widths have been measured on medium dispersion plates (7.0 and 12.4 Å mm-1) taken with the 152 cm coudé reflector at the Observatoire de Haute Provence (France). These results are also presented. The photographic plates were digitized by using a PDS 1010A microdensitometer. The spectroscopic data were reduced by means of a dedicated software package and an attempt was made to compute equivalent widths in a homogeneous way. T eff and logg parameters were estimated by using the computer to compare automatically the spectroscopic data with the value of theoretical models.
