Feasibility study of observing binary systems with the ASTRI Mini-array

Theorized by Glauber in the 1960s, Intensity Interferometry (II) has found applications in a wide variety of fields. The first to use it for astronomical measurements, albeit in its "analog" form, were Hanbury-Brown and Twiss, culminating their research by measuring the angular diameter of more than thirty stars from the Narrabri observatory, in Australia. Very recently, a research group at the University of Padua and at the Observatory of Padova of the National Institute of Astrophysics realized the first astronomical intensity interferometry measurement by means of a "quantum" approach, determining the second order correlation function of Vega using two ultrafast photon counting photometers coupled to two mid-class telescopes available at Asiago (Italy). Nowadays, due to the planned construction of large telescope arrays (e.g. CTA), and thanks to the enormous advances in electronics, II is acquiring a central role, with great prospects for the further characterization of various celestial bodies. In this context, the objective of this thesis is to evaluate, through simulations, the capabilities of the ASTRI Mini-array telescope system to characterize binary systems using the II technique.
