Summary: The asymptotics of the weighted $$L_{p}$$-norms of Hermite polynomials, which describes the Rényi entropy of order $$p$$ of the associated quantum oscillator probability density, is determined for $$n\to\infty$$ and $$p>0$$. Then, it is applied to the calculation of the Rényi entropy of the quantum-mechanical probability density of the highly-excited (Rydberg) states of the isotropic oscillator.
