ν’s can cool and heat matter, according to radial location: cooling region, close to PNS surface heating region, between Rgain and Rshock The gain radius Neutrinos in core collapse SN explosion - Paris, 10 September 2009 – p. 20/48
Results:ν luminosity after bounce νe burst close to bounce (t ∼ 5 ms after bounce) ¯νe and µ and τ ν’s luminosities rise behind the shock (high T ) spectra comparison at t = 100 ms after bounce: νe’s interact more → lower energy Liebendorfer et al.
