A Search for Chemical Anomalies of Seven A-types Stars
Yahya Nasolo, Şeyma Çalışkan
We present a chemical abundance analysis of seven A-type stars with no detailed chemical abundance measurements in the literature. High-resolution spectra of the targets HD 2924, H…
Detailed photospheric abundances of 28 Peg and HD 202240
Asli Elmasli, Seyma Caliskan, Tolgahan Kilicoglu +3
The atmospheric parameters and chemical abundances of two neglected A-type stars, 28 Peg and HD 202240, were derived using high resolution spectra obtained at the TUBITAK National…
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…
Chemical abundances of the metal-poor horizontal-branch stars CS 22186-005 and CS 30344-033
S. Caliskan, E. Caffau, P. Bonifacio +5
We report on a chemical-abundance analysis of two very metal-poor horizontal-branch stars in the Milky Way halo: CS 22186-005 ([Fe/H]=-2.70) and CS 30344-033 ([Fe/H]=-2.90). The an…
Physical Parameters of Some Close Binaries: ET Boo, V1123 Tau, V1191 Cyg, V1073 Cyg and V357 Peg
F. Ekmekçi, A. Elmaslı, M. Yılmaz +7
With the aim of providing new and up-to-date absolute parameters of some close binary systems, new BVR CCD photometry was carried out at the Ankara University Observatory (AUG) for…
Abundance analysis of the outer halo globular cluster Palomar 14
S. Caliskan, N. Christlieb, K. E. Grebel
We determine the elemental abundances of nine red giant stars belonging to Palomar 14 (Pal 14). Pal 14 is an outer halo globular cluster (GC) at a distance of \sim 70 kpc. Our abun…
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…
