Magnetic Doppler Imaging of Active Stars
O. Kochukhov, N. Piskunov
We present a new implementation of the magnetic Doppler imaging technique, which aims at self-consistent temperature and magnetic mapping of the surface structures in cool active s…
New Abundances for Old Stars - Atomic Diffusion at Work in NGC 6397
A. J. Korn, F. Grundahl, O. Richard +5
A homogeneous spectroscopic analysis of unevolved and evolved stars in the metal-poor globular cluster NGC 6397 with FLAMES-UVES reveals systematic trends of stellar surface abunda…
A probable stellar solution to the cosmological lithium discrepancy
A. J. Korn, F. Grundahl, O. Richard +5
The measurement of the cosmic microwave background has strongly constrained the cosmological parameters of the Universe. When the measured density of baryons (ordinary matter) is c…
Radiative transfer in Doppler Imaging
N. Piskunov
The modern Doppler Imaging (DI) technique allows the reconstruction of different stellar surface structures based on accurate calculation of spectra of specific intensity. New appl…
