The ALMA detection of CO rotational line emission in AGB stars in the Large Magellanic Cloud
... The TP-AGB models can explain the location of the ob- served stars in the P-L diagram. The sizable excursions of the tracks both in luminosity and pulsation period are driven by the occurrence of thermal pulses. ...

Chemistry and distribution of daughter species in the circumstellar envelopes of O-rich AGB stars
... Moreover, emission from polycyclic aromatic hydrocarbons (PAHs) and fullerenes C 60 have also surprisingly been found in O-rich binary post-AGB sources (Gielen et al. 2011). All of these studies clearly ...
