Gamma-Ray Line Astrophysics
The Compton Observatory instruments have measured several
g-ray lines, both from individual supernovae as well
as from the diffuse interstellar medium. At this late phase
of CGRO's mission, we will review the astrophysical achievements
by these observations of Galactic 511 keV annihilation radiation,
supernova lines at 78, 122, 847, 1238, and 1157 keV from 44Ti
and Co isotopes, and diffuse 1809 keV radioactivity emission from
26Al. We will discuss constraints on other candidate lines
such as 7Be and 22Na radioactivities from novae, and nuclear
12C and 16O de-excitation lines from Orion or the inner
Galaxy. The lessons from CGRO will be put in perspective with other
experiments of the past and future.
