An Analytical Approach to Scattering Between Two Thin Magnetic Flux Tubes in a Stratified Atmosphere

Chris S. Hanson, Paul S. Cally

We expand on recent studies to analytically model the behavior of two thin flux tubes interacting through the near- and acoustic far-field. The multiple scattering that occurs betw…

Constraining the Origin of Magnetar Flares

Bennett Link

Sudden relaxation of the magnetic field in the core of a magnetar produces mechanical energy primarily in the form of shear waves which propagate to the surface and enter the magne…

The impact of updated Zr neutron-capture cross sections and new asymptotic giant branch models on our understanding of the s process and the origin of stardust

Maria Lugaro, Giuseppe Tagliente, Amanda I. Karakas +4

We present model predictions for the Zr isotopic ratios produced by slow neutron captures in C-rich asymptotic giant branch (AGB) stars of masses 1.25 to 4 Msun and metallicities Z…

The Nature of Millisecond Pulsars with Helium White Dwarf Companions

Sarah L. Smedley, Christopher A. Tout, Lilia Ferrario +1

We examine the growing data set of binary millisecond pulsars that are thought to have a helium white dwarf companion. These systems are believed to form when a low- to intermediat…

Ellerman Bombs - Evidence for Magnetic Reconnection in the Lower Solar Atmosphere

C. J. Nelson, S. Shelyag, M. Mathioudakis +4

The presence of photospheric magnetic reconnection has long been thought to give rise to short and impulsive events, such as Ellerman bombs (EBs) and Type II spicules. In this arti…

Oblique Shock Breakout in Supernovae and Gamma-Ray Bursts: I. Dynamics and Observational Implications

Christopher D. Matzner, Yuri Levin, Stephen Ro

In a non-spherical stellar explosion, non-radial motions become important near the stellar surface. For realistic deviations from spherical symmetry, non-radial flow dramatically a…
