Resolving Binary Systems down to Milli-Arcsecond Precision through Stellar Intensity Interferometry with MAGIC and LST-1
We report on recent simulations and future prospects in Stellar Intensity Interferometry (SII) using the MAGIC and LST1 telescopes to study hot, massive binary systems. Through nanosecond-scale photon correlation measurements across long baselines, we aim to resolve sub-milliarcsecond stel- lar features and constrain key binary parameters, including angular separation, radii, and brightness ratios. Simulations of the spectroscopic binary 𝛼 Virginis (Spica) illustrate the capability of SII to resolve close binaries and validate models of stellar evolution. With the MAGIC–LST1 interfer- ometer, we also aim to identify interacting binary systems exhibiting wind collisions or Roche lobe overflow: environments that may host particle acceleration and produce very-high-energy (VHE, 𝐸 > 20 GeV) gamma-ray emission. Moreover, the short-period massive binaries accessible to SII are often progenitors of compact systems such as neutron star binaries or X-ray binaries, which are themselves key targets for VHE astroparticle-physics observations.
