Spectroscopic and Photometric Behaviour of LP Ori
Asli Elmasli, K. Ozge Unal, Dogus Ozuyar
We performed spectroscopic and photometric analyses on the early B-type LP Ori young stellar object located in the Orion Nebula. The high-resolution spectra of LP Ori was obtained…
The Period Analysis of the Hierarchical System DI Peg
Dogus Ozuyar, Asli Elmasli, Seyma Caliskan
The existence of an additional body around a binary system can be detected by the help of the light-travel time effect. Due to the motions of binary and the companion stars around…
Refined Chemical Abundances of Pi Dra and HR 7545 with ATLAS12
Doğuş Özuyar, Aslı Elmaslı, Şeyma Çalışkan
We present the more refined abundances of elements (C, O, Na, Mg, Al, Si, Ca, Sc, Ti, V, Cr, Mn, Fe, Ni, Zn, Sr, Y, Zr and Ba) determined using the computationally intensive ATLAS1…
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…
An In-Depth Spectroscopic Analysis of RR Lyr Variations over the Pulsation Cycle
L. Fossati, K. Kolenberg, D. V. Shulyak +5
The stellar parameters of RR Lyrae stars vary considerably over a pulsation cycle, and their determination is crucial for stellar modelling. We present a detailed spectroscopic ana…
Detection of a magnetic field in three old and inactive solar-like planet-hosting stars
L. Fossati, O. Kochukhov, J. S. Jenkins +4
Our understanding of magnetic fields in late-type stars is strongly driven by what we know of the solar magnetic field. For this reason, it is crucial to understand how typical the…
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…
A Spectroscopic Study of DD UMa: Ursa Major Group Member and Candidate for BRITE
A. Elmaslı, L. Fossati, C. P. Folsom +2
The Ursa Major group is a nearby stellar supercluster which, while not gravitationally bound, is defined by co-moving members. DD UMa is a Scuti star whose membership in the Ur…
The accuracy of stellar atmospheric parameter determinations: a case study with HD 32115 and HD 37594
L. Fossati, T. Ryabchikova, D. V. Shulyak +5
We present detailed parameter determinations of two chemically normal late A-type stars, HD 32115 and HD 37594, to uncover the reasons behind large discrepancies between two previo…
