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…
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…
Mixing and nucleosynthesis in rotating TP-AGB stars
N. Langer, A. Heger, S. Wellstein +1
We present the first evolutionary models of intermediate mass stars up to their thermal pulses which include effects of rotation on the stellar structure as well as rotationally in…
