New and updated stellar parameters for 71 evolved planet hosts. On the metallicity - giant planet connection
A. Mortier, N. C. Santos, S. G. Sousa +5
It is still being debated whether the well-known metallicity - giant planet correlation for dwarf stars is also valid for giant stars. For this reason, having precise metallicities…
SWEET-Cat: A catalogue of parameters for Stars With ExoplanETs I. New atmospheric parameters and masses for 48 stars with planets
N. C. Santos, S. G. Sousa, A. Mortier +8
Due to the importance that the star-planet relation has to our understanding of the planet formation process, the precise determination of stellar parameters for the ever increasin…
Atmospheric Parameters of 169 F, G, K and M-type Stars in the Kepler Field
J. Molenda-Zakowicz, S. G. Sousa, A. Frasca +15
The asteroseismic and planetary studies, like all research related to stars, need precise and accurate stellar atmospheric parameters as input. We aim at deriving the effective tem…
Deriving precise parameters for cool solar-type stars. Optimizing the iron line list
M. Tsantaki, S. G. Sousa, V. Zh. Adibekyan +3
Temperature, surface gravity, and metallicitity are basic stellar atmospheric parameters necessary to characterize a star. We aim to improve the description of the spectroscopic te…
Ultra-Luminous X-Ray Sources in the Most Metal Poor Galaxies
A. H. Prestwich, M. Tsantaki, A. Zezas +5
Ultra-Luminous X-ray sources (ULX) are X-ray binaries with Lx>1E^39 ergs/s. The most spectacular examples of ULX occur in starburst galaxies and are now understood to be young, lum…
