In an unstable Q-ball hairy black hole, the early growth of the weakly responding scalar component is dominated by a second-order QNM rather than its linear response.

At leading order in amplitude, linearized modes of thick-walled Q-balls in 1+1D are solved in closed form, with corotating modes resembling breathers and counterrotating modes becoming Feshbach quasinormal modes via an irrational Pöschl-Teller potential.
