A joint effort to discover and characterize two resonant mini Neptunes around TOI-1803 with TESS, HARPS-N and CHEOPS
T. Zingales, L. Malavolta, L. Borsato +130
We present the discovery of two mini Neptunes near a 2:1 orbital resonance configuration orbiting the K0 star TOI-1803. We describe their orbital architecture in detail and suggest…
The GAPS programme at TNG LXVI. A homogeneous search for Na i and its possible variability in ten gas giant exoplanets
D. Sicilia, L. Malavolta, G. Scandariato +18
The neutral sodium resonance doublet (Na i D) has been detected in the upper atmosphere of several close-in gas giants, through high-resolution transmission spectroscopy. We aim to…
Local integrability breaking and exponential localization of leading Lyapunov vectors
Jiaozi Wang, Tomaž Prosen, Giulio Casati
We study integrability breaking and transport in a discrete space-time lattice with a local integrability breaking perturbation. We find a singular distribution of the Lyapunov spe…
Episodic super-Eddington accretion as a clue to Overmassive Black Holes in the early Universe
Alessandro Trinca, Rosa Valiante, Raffaella Schneider +7
Early JWST observations are providing growing evidence for a ubiquitous population of accreting supermassive black holes (BHs) at high redshift, many of which appear overmassive co…
Is your stochastic signal really detectable?
Federico Pozzoli, Jonathan Gair, Riccardo Buscicchio +1
Separating a stochastic gravitational wave background (SGWB) from noise is a challenging statistical task. One approach to establishing a detection criterion for the SGWB is using…
Interaction-induced phases in the half-filled Bernevig-Hughes-Zhang model in one dimension
Roberta Favata, Davide Piccioni, Alberto Parola +1
We explore the ground-state properties of a one-dimensional model with two orbitals per site, where, in addition to atomic energies , intra- and inter-orbital hoppings, the…
