HR 8844: a new transition object between the Am stars and the HgMn stars ?
R. Monier, M. Gebran, F. Royer +2
While monitoring a sample of apparently slowly rotating superficially normal early A stars, we have discovered that HR 8844 (A0 V), is actually a new Chemically Peculiar star. We h…
The chemical compositions of the 2 new HgMn stars HD 30085 and HD 30963. Comparison to Lupi A, Cap and HD 174567
R. Monier, E. Griffin, M. Gebran +3
We report on a detailed abundance study of the fairly bright slow rotators HD 30085 (A0 IV), HD 30963 (B9 III) and HD 174567 (A0 V), hitherto reported as normal stars and the sharp…
Elemental Abundance Analysis of the Early Type Members of the Open Cluster M6: Preliminary Results
T. Kilicoglu, R. Monier, L. Fossati
Differences in chemical composition among main sequence stars within a given cluster are probably due to differences in their masses and other effects such as radiative diffusion,…
Photometric analysis of overcontact binaries AK Her, HI Dra, V1128 Tau and V2612 Oph
S. Caliskan, O. Latkovic, G. Djurasevic +7
We analyze new, high quality multicolor light curves of four overcontact binaries: AK Her, HI Dra, V1128 Tau and V2612 Oph, and determine their orbital and physical parameters usin…
Mass-effective temperature-surface gravity relation for intermediate-mass main-sequence stars
T. Kilicoglu
In this work, a mass-effective temperature-surface gravity relation (MTGR) is developed for main sequence stars in the range of 6400 K < < 20000 K with log > 3.44.…
Physical parameters of close binaries QX Andromedae, RW Comae Berenices, MR Delphini, and BD +07{\circ} 3142
G. Djurasevic, M. Yilmaz, O. Basturk +3
Aims. We analyze new multicolor light curves and recently published radial velocity curves for close binaries QX And, RW Com, MR Del, and BD +07{\circ} 3142 to determine the physic…
