We study the evolution of G2 in a textit{Compact Source Scenario}, where G2 is the outflow from a low-mass central star moving on the observed orbit. This is done through 3D AMR simulations of the hydrodynamic interaction of G2 with the surrounding hot accretion flow. A comparison with observations is done by means of mock position-velocity (PV) diagrams. We found that a massive ($dot{M}_mathrm{w}=5times 10^{-7} ;M_{odot} ; mathrm{yr^{-1}}$) and slow ($v_mathrm{w}=50 ;mathrm{km; s^{-1}}$) outflow can reproduce G2s properties. A faster outflow ($v_mathrm{w}=400 ;mathrm{km; s^{-1}}$) might also be able to explain the material that seems to follow G2 on the same orbit.
