Thermal pulses play a key role in the evolution of chemical elements, via the nucleosynthesis, and mixing of new elements that 
are transported to the surface of the star via dredge-up.
WISE J1810-3305 is an object which recently became much brighter in the mid-infrared and is possibly a source undergoing a 
thermal pulse (Gandhi et al. (2012).
Using  K/L band NACO observations obtained  and 1D radiative transfer modeling, we confirmed that this star experienced a 
dramatic ejection event that lead to the formation of a thick dusty detached shell..
This would be the first time such an event is observed around an AGB star.
