Observations in the near-infrared domain showed the presence of the flat coreof bright late-type stars inside $\sim 0.5\,{\rm pc}$ from the Galactic centersupermassive black hole (Sgr A*), while young massive OB/Wolf-Rayet stars forma cusp. Several dynamical processes were proposed to explain this apparentparadox of the distribution of the Galactic center stellar populations. Giventhe mounting evidence about a significantly increased activity of Sgr A* duringthe past million years, we propose a scenario based on the interaction betweenthe late-type giants and a nuclear jet, whose past existence and energetics canbe inferred from the presence of $\gamma$-ray Fermi bubbles and bipolar radiobubbles. Extended, loose envelopes of red giant stars can be ablated by the jetwith kinetic luminosity in the range of $L_{\rm j}\approx10^{41}$-$10^{44}\,{\rm erg\,s^{-1}}$ within the inner $\sim 0.04\,{\rm pc}$ ofSgr A* (S cluster region), which would lead to their infrared luminositydecrease after several thousand jet-star interactions. The ablation of theatmospheres of red giants is complemented by the process of tidal strippingthat operates at distances of $\lesssim 1\,{\rm mpc}$, and by the directmechanical interaction of stars with a clumpy disc at $\gtrsim 0.04\,{\rm pc}$,which can explain the flat density profile of bright late-type stars inside theinner half parsec from Sgr A*.
