Limits to the Cas A Ti Line Flux and Constraints on the Ejecta Energy and the Compact Source
R. E. Rothschild, R. E. Lingenfelter
Two long observations of Cas A supernova remnant were made by the \emph{Rossi X-ray Timing Explorer} in 1996 and 1997 to search for hard X-ray line emission at 67.9 and 78.4 keV fr…
Solar Activity and Cloud Opacity Variations: A Modulated Cosmic-Ray Ionization Model
David Marsden, Richard E. Lingenfelter
The observed correlation between global low cloud amount and the flux of high energy cosmic rays supports the idea that ionization plays a crucial role in tropospheric cloud format…
Issues of LiBeB, Oxygen and Iron Evolution
R. Ramaty, R. E. Lingenfelter, B. Kozlovsky
We discuss the highlights of our recent research, specifically the refractory vs. volatile interpretation of the rise of [O/Fe] with decreasing [Fe/H], and the issue of primary vs.…
LiBeB: High and low energy cosmic ray production and comparison with neutrino induced nucleosynthesis in SNII
R. Ramaty, H. Reeves, R. E. Lingenfelter +1
We present new calculations of LiBeB production by accelerated particles with various compositions and energy spectra ranging from low energies to relativistic energies, and variou…
Astrophysical Gamma Ray Emission Lines
R. Ramaty, R. E. Lingenfelter
We review the wide range of astrophysical observations of gamma ray emission lines and we discuss their implications. We consider line emission from solar flares, the Orion molecul…
