Title: Super-eccentric hot Jupiters and High energy emission from Supernovae

Abstract:
They are out there, they are detectable and they are crucial theoretically. Detection of highly eccentric (e>~ 0.99) extra-solar gas-giants with periastron of a few stellar radii may answer the question of how hot Jupiters get so close to their host star. Detection of early high energy emission (soft X-ray to gamma-rays) at the onset of Supernovae will allow us to measure key properties of the exploding star, including its pre-explosion radius and the blast wave velocity
