    1 1. High mass loss rate AGB star need a large atmosphere. Its photosphere will be around 1.5au. [http://adsabs.harvard.edu/abs/2016A%26A...589A.130L Liljegren et al. (2016)] use 1.5au AGB and achieved $3\times10^{-6}M_{\odot}/yr$. However, 1.5au will be too large for us. The tidal force will be 50% of the gravitational force from the AGB star. The highest mass loss rate I can do is $10^{-7}M_{\odot}/yr$. Below is the mass loss rate in 3-D simulation. I sum the mass flux through a 10 AU spherical shell. The luminosity of this AGB star is $2343L_{\odot}$ and mass is $1M_{\odot}$. So the mass loss rate and size is not between RGB and super AGB.
