Eating planets makes you younger: The magnetic dynamo rejuvenation of GJ 504 by planetary engulfment
S. Bellotti, C. Pezzotti, G. Buldgen +3
With the discovery of a few thousand exoplanets, questions have been raised regarding star-planet interactions and whether the presence of a companion may affect stellar properties…
Fractional Cointegration of Geometric Functionals
Alessia Caponera, Domenico Marinucci, Anna Vidotto
In this paper, we show that geometric functionals (e.g., excursion area, boundary length) evaluated on excursion sets of sphere-cross-time long memory random fields can exhibit fra…
Functional second-order Gaussian Poincaré inequalities
Anna Vidotto, Guangqu Zheng
In this paper, we work in the framework of Hilbert-valued Wiener structures and derive a functional version of the second-order Gaussian Poincaré inequality that leads to abstract…
Time changed spherical Brownian motions with longitudinal drifts
Giacomo Ascione, Anna Vidotto
In this paper, we consider the time change of the diffusion process on the 2-dimensional unit sphere generated by the Laplace-Beltrami operator, perturbed by means of a longitudina…
Multi-Scale CUSUM Tests for Time Dependent Spherical Random Fields
Alessia Caponera, Domenico Marinucci, Anna Vidotto
This paper investigates the asymptotic behavior of structural break tests in the harmonic domain for time dependent spherical random fields. In particular, we prove a functional ce…
Functional Convergence of Berry's Nodal Lengths: Approximate Tightness and Total Disorder
Massimo Notarnicola, Giovanni Peccati, Anna Vidotto
We consider Berry's random planar wave model (1977), and prove spatial functional limit theorems - in the high-energy limit - for discretized and truncated versions of the random f…
