  We describe a three-dimensional simulation of a $1 M_{\odot}$ solar-type star
approaching a $10^{6} M_{\odot}$ black hole on a parabolic orbit with a
pericenter distance well within the tidal radius. While falling towards the
black hole, the star is not only stretched along the orbital direction but even
more severely compressed at right angles to the orbit. The overbearing degree
of compression achieved shortly after pericenter leads to the production of
strong shocks which largely homogenize the temperature profile of the star,
resulting in surface temperatures comparable to the initial temperature of the
star's core. This phenomenon, which precedes the fallback accretion phase,
gives rise to a unique double-peaked X-ray signature that, if detected, may be
one of the few observable diagnostics of how stars behave under the influence
of strong gravitational fields. If $\sim 10^{6} M_{\odot}$ black holes were
prevalent in small or even dwarf galaxies, the nearest of such flares may be
detectable by EXIST from no further away than the Virgo Cluster.
