Abstract

Our model, involving cosmic ray acceleration by supernova remnants,
with subsequent Galactic propagation, has been applied to the
astrophysically interesting problem of the reason for differences in
the spectra of the various Galactic mass components.
When allowance is made for the likely differences in mass composition
of the dust and gas in the interstellar medium between the local region
containing the 'hot bubble' (within similar or equal to 200 pc) and
that further afield, and the likelihood of a recent supernova in the
local region, support appears for our model.
