Sector models - A toolkit for teaching general relativity: II. Geodesics
Corvin Zahn, Ute Kraus
Sector models are tools that make it possible to teach the basic principles of the general theory of relativity without going beyond elementary mathematics. This contribution shows…
Sector models - A toolkit for teaching general relativity: III. Spacetime geodesics
Ute Kraus, Corvin Zahn
Sector models permit a model-based approach to the general theory of relativity. The approach has its focus on the geometric concepts and uses no more than elementary mathematics.…
Sector Models - A Toolkit for Teaching General Relativity. Part 1: Curved Spaces and Spacetimes
C. Zahn, U. Kraus
Teaching the general theory of relativity to high school or undergraduate students must be based on an approach that is conceptual rather than mathematical. In this paper we presen…
Analyzing X-ray pulsar profiles: geometry and beam pattern of A 0535+26
I. Caballero, U. Kraus, A. Santangelo +2
We applied a decomposition method to the energy dependent pulse profiles of the accreting binary pulsar A 0535+26, in order to identify the contribution of the two magnetic poles o…
Analyzing X-Ray Pulsar Profiles: Geometry and Beam Pattern of EXO 2030+375
Manami Sasaki, Dmitry Klochkov, Ute Kraus +2
The pulse profiles of the transient Be/X-ray binary EXO 2030+375 show strong dependence on energy, as well as on its luminosity state, and are asymmetric in shape. We want to ident…
A 0535+26 in outburst: magnetospheric instabilities and accretion geometry
I. Caballero, U. Kraus, K. Postnov +4
The Be/X-ray binary A 0535+26 showed a normal (type I) outburst in August/September 2005, which reached a maximum X-ray flux of 400mCrab in the 5-100keV range. The outburst was obs…
