  This white paper briefly summarizes stellar science opportunities enabled by
ultra-high resolution (sub-100 {\mu} arc-sec) astronomical imaging in the
visible (U/V) wavebands. Next generation arrays of Imaging Cherenkov
telescopes, to be constructed in the next decade, can provide unprecedented
visible band imaging of several thousand bright (m< 6), hot (O/B/A) stars using
a modern implementation of Stellar Intensity Interferometry (SII). This white
paper describes the astrophysics/astronomy science opportunities that may be
uncovered in this new observation space during the next decade.
