AG Antliae or HD 89353 is a Post-AGB Star.

" Post-AGB stars are among the most important sources of dust enrichment of the interstellar medium. Molster et al. (2002, A&A, 382, 184) investigated the mineralogy and occurrence of crystalline silicate grain features around evolved stars. " The Spatial Distribution of Grains Around the Dual Chemistry Post-AGB Star

" A synthetic method for tracing the evolution of the post-AGB stars. " Synthetic post-AGB evolution

" In order to study in a general manner the pulsations of the post-AGB stars we performed a grid of non-linear radiative low-mass, high-luminosity models in a wide range of Teff, L and M. " Non-linear radiative models of post-AGB stars: Application to HD 56126

" We construct a data base of 125 post-AGB objects (including R CrB and extreme helium stars) with published photospheric parameters (effective temperature and gravity) and chemical composition. We estimate the masses of the post-AGB stars by comparing their position in the (log , log g) plane with theoretical evolutionary tracks of different masses. " Post-AGB stars as testbeds of nucleosynthesis in AGB stars

" We present new numerical hydrodynamical modelling of the evolution of Asymptotic Giant Branch (AGB) mass loss fluctuations during the post-AGB/Planetary Nebula phase. " The post-AGB evolution of AGB mass loss variations
