A Census of Chemically Peculiar Stars in Stellar Associations
Lukas KueÃ, Ernst Paunzen
The pre-main-sequence evolution of the chemically peculiar (CP) stars on the upper main sequence is still a vast mystery and not well understood. Our analysis of young associations…
The Status of the Astrophysical Parameters of Upper Main Sequence Stars
Lukas KueÃ, Ernst Paunzen
Calibrating the ages, masses, and radii of stars on the upper main sequence depends heavily on accurate measurements of the effective temperature () and surface gra…
Lightcurves of stars in the Chamaeleon I Association
K. Neumannová, L. KueÃ, E. Paunzen +1
Star-forming regions are essential for studying very young stellar objects of various masses. They still contain a significant amount of dust and gas. We present a study of light c…
GALEX UV survey of magnetic chemically peculiar stars in the Kepler prime field
Emanuele Bertone, Stefan Hümmerich, Miguel Chávez +8
Magnetic chemically peculiar (mCP) stars are strongly magnetic upper main-sequence stars that exhibit light rotational variability due to an uneven surface distribution of certain…
