  In a 1996 JRO Fellowship Research Proposal (Los Alamos), the author suggested
that neutrino oscillations may provide a powerful indirect energy transport
mechanism to supernovae explosions. The principal aim of this addendum is to
present the relevant unedited text of Section 1 of that proposal. We then
briefly remind, (a) of an early suggestion of Mazurek on vacuum neutrino
oscillations and their relevance to supernovae explosion, and (b) Wolfenstein's
result on suppression of the effect by matter effects. We conclude that whether
or not neutrino oscillations play a significant role in supernovae explosions
shall depend if there are shells/regions of space in stellar collapse where
matter effects play no essential role. Should such regions exist in actual
astrophysical situations, the final outcome of neutrino oscillations on
supernovae explosions shall depend, in part, on whether or not the LNSD signal
is confirmed. Importantly, the reader is reminded that neutrino oscillations
form a set of flavor-oscillation clocks and these clock suffer gravitational
redshift which can be as large as 20 percent. This effect must be incorporated
fully into any calculation of supernova explosion.
