Deep-Focus Diagnostics of Sunspot Structure

H. Moradi, S. M. Hanasoge

In sequel to Moradi et al. [2009, ApJ, 690, L72], we employ two established numerical forward models (a 3D ideal MHD solver and MHD ray theory) in conjunction with time-distance he…

Thermohaline Mixing and its Role in the Evolution of Carbon and Nitrogen Abundances in Globular Cluster Red Giants: The Test Case of Messier 3

George C. Angelou, Ross P. Church, Richard J. Stancliffe +2

We review the observational evidence for extra mixing in stars on the red giant branch (RGB) and discuss why thermohaline mixing is a strong candidate mechanism. We recall the simp…

Resonant Absorption as Mode Conversion? II. Temporal Ray Bundle

C S Hanson, P S Cally

A fast-wave pulse in a simple, cold, inhomogeneous MHD model plasma is constructed by Fourier superposition over frequency of harmonic waves that are singular at their respective A…

On the linear coupling between fast and slow MHD waves due to line-tying effects

J. Terradas, J. Andries, E. Verwichte

Oscillations in coronal loops are usually interpreted in terms of uncoupled magnetohydrodynamic (MHD) waves. Examples of these waves are standing transverse motions, interpreted as…

Radioactivities in Low- and Intermediate-Mass Stars

Maria Lugaro, Alessandro Chieffi

Energy in stars is provided by nuclear reactions, which, in many cases, produce radioactive nuclei. When stable nuclei are irradiated by a flux of protons or neutrons, capture reac…

Evolution and nucleosynthesis of extremely metal-poor and metal-free low- and intermediate-mass stars II. s-process nucleosynthesis during the core He flash

Simon W. Campbell, Maria Lugaro, Amanda I. Karakas

Models of primordial and hyper-metal-poor stars with masses similar to the Sun experience an ingestion of protons into the hot core during the core helium flash phase at the end of…
