We present self-consistent dynamical models for dust-driven winds of carbon-rich AGB stars. The models are based on the coupled system of frequency-dependent radiation hydrodynamic…
IceCube - the next generation neutrino telescope at the South Pole
A. Karle
IceCube is a large neutrino telescope of the next generation to be constructed in the Antarctic Ice Sheet near the South Pole. We present the conceptual design and the sensitivity…
Dust grain properties in atmospheres of AGB stars
A. C. Andersen, S. Hoefner, R. Gautschy-Loidl
We present self-consistent dynamical models for dust driven winds of carbon-rich AGB stars. The models are based on the coupled system of frequency-dependent radiation hydrodynamic…
Does Betelgeuse have a magnetic field?
S. B. F. Dorch, B. Freytag
Recent numerical simulations by Freytag et al. of the outer convection envelope of the cool super-giant Betelgeuse, have shown that the fluctuations in the star's apparent luminosi…
Multipair contributions to the spin response of nuclear matter
E. Olsson, C. J. Pethick
We analyse the effect of non-central forces on the magnetic susceptibility of degenerate Fermi systems. These include the presence of contributions from transitions to states conta…
