NLTE Spectral Analysis of Central Stars of PNe Interacting with the ISM
T. Rauch, F. Kerber, E. Furlan +1
The analysis of Planetary Nebulae (PNe) provides a tool to investigate the properties of their exciting central stars (CSPN) at the moment of the PN ejection as well as on the prop…
What the Infrared Behavior of QCD Green Functions can tell us about Confinement in the Covariant Gauge
Lorenz von Smekal, Reinhard Alkofer
We review aspects of confinement in the covariant and local description of QCD and discuss to what extend our present knowledge of the infrared behavior of QCD Green functions can…
Spectral analysis of multi mode pulsating sdB stars II. Feige 48, KPD 2109+4401 and PG 1219+534
U. Heber, I. N. Reid, K. Werner
Three members of the new class of pulsating sdB stars (sdBV or EC 14026 stars) are analysed from Keck HIRES spectra using line blanketed NLTE and LTE model atmospheres. Atmospheric…
A Solution to Coupled Dyson-Schwinger Equations for Gluons and Ghosts in Landau Gauge
Andreas Hauck, Reinhard Alkofer, Lorenz von Smekal
A truncation scheme for the Dyson-Schwinger equations of QCD in Landau gauge is presented which implements the Slavnov-Taylor identities for the 3-point vertex functions. Neglectin…
