Description

Stellar intensity interferometry (SII) enables optical measurements at sub-milliarcsecond resolution, offering the potential to open powerful new avenues for astrophysical discovery. With its ability to probe stellar surfaces, SII may allow constraints on temperature gradients, star spots, rotation, and limb darkening at unprecedented detail. Close binary systems could become accessible for precise orbit and mass determinations, while circumstellar disks and winds may be studied to advance our understanding of stellar evolution and mass loss. Extending to extragalactic targets, SII holds promise for constraining the environments of supernova progenitors and the compact regions of active galactic nuclei. In the following talk, I will review various science cases that illustrate this potential.
