An all-sky catalogue of stellar reddening values
E. Paunzen, M. Netopil, M. Prisegen +1
When observing astronomical objects, we must deal with extinction (i.e. the absorption and scattering of the emitted radiation by dust and gas between the source and the observer).…
Study of the Open Clusters in Kepler Prime Field
Yüksel Karataş, Hikmet Çakmak, İnci Akkaya Oralhan +3
We present a detailed study of NGC 6791, NGC 6811, NGC 6819 and NGC 6866, the four open clusters that are located in the Kepler prime field. We use new CCD UBV(RI)KC photometry, wh…
The Galactic metallicity gradient shown by open clusters in the light of radial migration
Martin Netopil, İnci Akkaya Oralhan, Hikmet Çakmak +2
During the last years and decades several individual studies and large-scale spectroscopic surveys significantly improved our knowledge of the Galactic metallicity distribution bas…
A search for peculiar stars in the open cluster Hogg 16
Stefano Cariddi, Naira M. Azatyan, Petr Kurfürst +5
The study of chemically peculiar (CP) stars in open clusters provides valuable information about their evolutionary status. Their detection can be performed using the photomet…
Metallicity calibrations for dwarf stars and giants in the Geneva photometric system
Martin Netopil
We use the most homogeneous seven-colour photometric system to derive new metallicity calibrations for early A- to K-type stars that cover both, dwarf stars and giants. Th…
An Investigation of the Rotational Properties of Magnetic Chemically Peculiar Stars
Martin Netopil, Ernst Paunzen, Stefan Hümmerich +1
The magnetic chemically peculiar (mCP) stars of the upper main sequence exhibit strong, globally-organised magnetic fields which are inclined to the rotational axis and facilitate…
