Carbon and Oxygen abundances across the Hertzsprung gap
Jens Adamczak, David L. Lambert
We derived atmospheric parameters and spectroscopic abundances for C and O for a large sample of stars located in the Hertzsprung gap in the Hertzsprung-Russell Diagram in order to…

Atmospheric composition of weak G band stars: CNO and Li abundances
Jens Adamczak, David L. Lambert
We determined the chemical composition of a large sample of weak G band stars -- a rare class of G and K giants of intermediate mass with unusual abundances of C, N, and Li. We hav…

Chandra grating spectroscopy of three hot white dwarfs
J. Adamczak, K. Werner, T. Rauch +3
High-resolution soft X-ray spectroscopic observations of single hot white dwarfs are scarce. With the Chandra Low-Energy Transmission Grating, we have observed two white dwarfs, on…
