Wind fluctuations observed for the [WC9] nucleus of the planetary nebula BD+30 3639.

ACKER A., GROSDIDIER Y. and DURAND S.

Abstract (from CDS):

The CIII and CIV lines in the [WC9] spectrum of BD+30 3639 show variable features, interpreted in terms of radiative acceleration of "blobs" forming in the wind. The variations are like those observed for the WC9 massive stars, and the blobs acceleration appears smaller than for the [WC8] nucleus of NGC 40.
