B[e] stars. VIII. MWC 342.

ANDRILLAT Y. and JASCHEK C.

Abstract (from CDS):

On the basis of spectroscopic CCD material obtained at the Haute Provence Observatory, we provide line identifications and equivalent width measurements in the wavelength region 4095-8935 Å of the spectrum of MWC 342. Two hundred eighty emission features are identified and eighteen absorption features. Nine interstellar bands could be identified. Some of the remaining absorption lines correspond to a B0 type star. The cooler emission lines correspond to a spectrum of an early A-type star. The temperatures derived from both spectral types (29000 and 9000K) are in excellent agreement with the temperatures derived by photometrists.
