It appears that for white-dwarfs, the answer is supernova, if the masses are large enough: see http://arxiv.org/abs/1505.04444, a blog discussing the paper is here: http://astrobites.org/2015/06/03/detonating-white-dwarfs-with-black-holes/ On the grounds that the link above specifically discussed white-dwarfs, I am guessing that for the lower density of a ...

The micro black hole would be unable to accrete very quickly at all due to intense radiation pressure. The intense Hawking radiation would have an luminosity of $3.6 \times 10^{14}$ W, and a roughly isotropic flux at the event horizon of $\sim 10^{48}$ W m$^{-2}$. The Eddington limit for such an object is only $6 \times 10^{9}$ W. In other words, at this ...

This might help: http://xaonon.dyndns.org/hawking/ 10^9 KG gives it: a temperature of 1.227203e+14 Kelvin and a luminosity of 3.563442e+14 watts and a size about 500 times smaller than a proton by radius - that would make an absorption rate equivalent to its Hawking radiation pretty difficult because it's over five orders of magnitude hotter than the ...

The intense flux of Hawking radiation of about $10^{13}$ Watt will prevent any solar matter from coming close to the event horizon. So, the Hawking radiation creates a small bubble preventing it from growing by accretion.
