Dust around AFGL 2688, molecular shielding, and the production of carbon chain moleculesThe molecular, IR, and optical maps of the evolved carbon star AFGL 2688 (the 'Egg' Nebula) are all consistent with a model of a bipolar outflow of approximately 0.0001 solar masses/yr that stopped as this object evolved beyond the asymptotic giant branch about 200 years ago. In order to explain the extended HC7N emission around this star, it is proposed that carbon grains are collisionally fragmented as they supersonically steam through the circumstellar envelope.
