3D AMR simulations of G2 as an outflow

We study the evolution of G2 in a $\mathit{\text{Compact}}\mathit{\text{Source}}\mathit{\text{Scenario}}$, 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 (${\dot{M}}_{\mathrm{w}}=5\times {10}^{-7}{M}_{\odot }\mathrm{y}{\mathrm{r}}^{-1}$) and slow ($v_{\mathrm{w}}=50\mathrm{k}\mathrm{m}{\mathrm{s}}^{-1}$) outflow can reproduce G2’s properties. A faster outflow ($v_{\mathrm{w}}=400\mathrm{k}\mathrm{m}{\mathrm{s}}^{-1}$) might also be able to explain the material that seems to follow G2 on the same orbit.
