Changes in the value of the polytropic index of the stellar remnant resulting from partial disruptions for selected initial values of its β. Densities and radii are normalised to the central density and the radius of the remnant. Black curves represent solutions to the Lane-Emden equation for different values of γ; red, green, and blue points are from some of our simulations that left a remnant, for three different values of β. Left panel: γ = 5/3 polytrope. Right panel: γ = 4/3 polytrope.
