A Deep Chandra Observation of Kepler's Supernova Remnant: A Type Ia Event with Circumstellar Interaction
S. P. Reynolds, K. J. Borkowski, U. Hwang +4
We present initial results of a 750 ks Chandra observation of the remnant of Kepler's supernova of AD 1604. The strength and prominence of iron emission, together with the absence…
Ion Charge States in Halo CMEs: What can we Learn about the Explosion?
Cara E. Rakowski, J. Martin Laming, Susan T. Lepri
We describe a new modeling approach to develop a more quantitative understanding of the charge state distributions of the ions of various elements detected in situ during halo Coro…
Ion Charge States in the Fast Solar Wind: New Data Analysis and Theoretical Refinements
J. Martin Laming, Susan T. Lepri
We present a further investigation into the increased ionization observed in element charge states in the fast solar wind compared to its coronal hole source regions. Once ions beg…
Analytic Approach to the Stability of Standing Accretion Shocks: Application to Core-Collapse Supernovae
J. Martin Laming
We explore an analytic model of the accretion shock in the post bounce phase of a core-collapse supernova explosion. We find growing oscillations of the shock in the l=1 and l=2 mo…
