B[e] phenomenon extending to lower luminosities in the Magellanic Clouds.

GUMMERSBACH C.A., ZICKGRAF F.-J. and WOLF B.

Abstract (from CDS):

An analysis of the four recently discovered B[e] stars HenS35, S59, S93, and S137 in the Large Magellanic Cloud has been carried out using low-resolution IUE spectra, ESO 3.6-m CASPEC spectra, and ESO 0.5-m and 1-m UBV and JHK photometry, respectively. LTE model atmospheres have been fitted to the observed continuum energy distributions in order to derive the stellar parameters. The results are Teff=22000K, R=28R☉, and logL/L☉=5.2 for HenS35, Teff=14000K, R=16R☉, and logL/L☉=4.0 for HenS59, and Teff=13000K, R=26R☉, and logL/L☉=4.2 for HenS137. The presence of absorption lines in the optical spectrum of the B9[e]Ib star HenS93 allowed an additional LTE line analysis for this star using Balmer, HeI, SIII, MgII, and FeII lines to derive Teff=10000K, R=73R☉, logL/L☉=4.7, logg=1.75, ξ=10km/s, vsin i=65km/s, and M>14M☉. Our investigation shows that the class of B[e] stars in the Magellanic Clouds extends to luminosities of about logL/L☉=4, i.e. much lower than those of the previously studied B[e] supergiants. This result reinforces the importance of axial symmetry in large regions of the Hertzsprung-Russell diagram.
