Stellar magnetic activity and their influence on the habitability of exoplanets
T. Lüftinger, M. Güdel, C. P. Johnstone
Stellar magnetism, explorable via polarimetry, is a crucial driver of activity, ionization, photodissociation, chemistry and winds in stellar environments. Thus it has an important…
Short-period stellar activity cycles with Kepler photometry
Oleksiy V. Arkhypov, Maxim L. Khodachenko, Helmut Lammer +3
We study the short-periodic component of stellar activity with a cycle periods Pcyc up to 1000 days using the Kepler mission photometry of fast-rotating (rotational periods from 1…
Stellar Winds on the Main-Sequence I: Wind Model
C. P. Johnstone, M. Güdel, T. Lüftinger +2
Aims: We develop a method for estimating the properties of stellar winds for low-mass main-sequence stars between masses of 0.4 and 1.1 solar masses at a range of distances from th…
Stellar Winds on the Main-Sequence II: the Evolution of Rotation and Winds
C. P. Johnstone, M. Güdel, I. Brott +1
Aims: We study the evolution of stellar rotation and wind properties for low-mass main-sequence stars. Our aim is to use rotational evolution models to constrain the mass loss rate…
Visual and ultraviolet flux variability of the bright CP star Aur
J. Krticka, Z. Mikulasek, T. Luftinger +1
Chemically peculiar stars of the upper part of the main sequence show periodical variability in line intensities and continua, modulated by the stellar rotation, which is attribute…
GAUDI: a preparatory archive for the COROT mission
E. Solano, C. Catala, R. Garrido +34
The GAUDI database (Ground-based Asteroseismology Uniform Database Interface, http://sdc.laeff.esa.es/gaudi/) is a preparatory archive for the COROT (COnvection, ROtation and plane…
