Abundances and kinematics of a candidate sub-damped Lyman-alpha galaxy toward PHL 1226
L. Christensen, R. E. Schulte-Ladbeck, S. F. Sanchez +5
The spectrum of the quasar PHL 1226 is known to have a strong Mg II and sub-damped Lyman-alpha (sub-DLA) absorption line system with N(HI)=(5+/-2)*10^19 cm^-2 at z=0.1602. Using in…
Decomposition of AGN host galaxy images
B. Kuhlbrodt, L. Wisotzki, K. Jahnke
We describe an algorithm to decompose deep images of Active Galactic Nuclei into host galaxy and nuclear components. Currently supported are three galaxy models: A de-Vaucouleurs s…
Quasar host galaxy star formation activity from multicolour data
K. Jahnke, B. Kuhlbrodt, L. Wisotzki
We investigate multicolour imaging data of a complete sample of 19 low redshift (z<0.2) quasar host galaxies. The sample was imaged in four optical (BVRi) and three near-infrared b…
The Occurrence of the Hall--Instability in Crusts of Isolated Neutron Stars
M. Rheinhardt, D. Konenkov, U. Geppert
In former papers we showed that during the decay of a neutron star's magnetic field under the influence of the Hall--drift, an unstable rise of small--scale field structures at the…
QSO host galaxy star formation history from multicolour data
K. Jahnke, B. Kuhlbrodt, E. Orndahl +1
We investigate multicolour imaging data of a complete sample of low redshift (z<0.2) QSO host galaxies. The sample was imaged in four optical (BVRi) and three near-infrared bands (…
Formation of the Neutron Donor C13 in AGB Stars by Overshoot and Rotation
Falk Herwig, Norbert Langer
(abridged) Observations clearly show that low-mass AGB stars can provide a nucleosynthesis site of the s-process. Recent stellar evolution models indicate that radiative burning of…
