ROSAT X-ray observations of the interacting pair of galaxie NGC 4410: evidence for a central starburst
D. Tsch"oke, G. Hensler, N. Junkes
We present X-ray observations of the interacting pair of galaxies NGC 4410a/b with the ROSAT HRI and PSPC. The ROSAT HRI images reveal a point-like source corresponding to NGC 4410…

Chemical Abundance Ratios and Gas-Phase Mixing in Dwarf Galaxy Evolution
G. Hensler, A. Rieschick
Because of their low gravitational energies dwarf galaxies are greatly exposed to energetical influences by the interstellar medium, like e.g.\ stellar radiation, winds or explosio…

Chemical Evolution of Galaxies and the Relevance of Gas Processes
G. Hensler, A. Rieschick
Since stellar populations enhance particular element abundances according to the yields and lifetimes of the stellar progenitors, the chemical evolution of galaxies serves as one o…
