It is these enriched layers of the photosphere that are lost in repeating pulses. Once distant from the surface, the carbon fraction of this ejected material begins to glow at approximately 1000

The thin shell of helium fusion eventually caused enough expansion to moderate, or even extinguish its own reaction. The star once again began to collapse.

some variety of spiral. This is thought to be the result of the dueling solar winds in binary systems, which compress clouds of dust into distinct shock fronts. The concentric nature of WR 140's dust shells is not well understood, although it may be related to nuclear processes in the WolfâRayet star's core.

This helium fusion once again stalled, and the subsequent gravitational collapse dislodged another layer of photosphere into space. These pulses will continue as long as

The dust typically emitted by WolfâRayet systems is not so coherent or concentric as those of WR 140. The dust lanes around WolfâRayets are most commonly observed as
