Oral Presentation

Molecules in S-type AGB stars

Author(s): Xiaohu Li

Presenter: Xiaohu Li (ASIAA)

The composition of S-type Asymptotic Giant Branch (AGB) stars, which have C/O ratios of approximately one and the circumstellar envelopes (CSEs) possessing the dual chemical features of both C-rich and O-rich stars, is less-known. I will present the latest simulation results on the detectable molecules (for example by SMA) in the winds of S-type stars. This is based on results from the latest Herschel/HIFI observations of S-type AGB stars, and progress in accurately studying the chemical influence of N2 (and CO) photodissociation in a 3D radiation field.
