Spectral Disentangling Reveals Deep CNO-cycle Exposure in ET Cru
Gökhan Yücel, Volkan BakıÅ, Christian Nitschelm +2
Binary stars undergoing mass transfer provide unique laboratories for testing stellar evolution. Here, we present a comprehensive photometric and spectroscopic analysis of the semi…
Predictions of Stellar Occultations by Haumea and the Event of 4 May 2026
José Luis Ortiz, Nicolas Morales, Antonio Ocaña-Pastor +8
Haumea is the third-largest of the five officially recognized dwarf planets and one of the four that reside in the trans-Neptunian region. It is among the most exotic bodies in the…
V570 Per: Characterization of a Benchmark Eclipsing Binary
Gökhan Yücel, Neslihan Alan, Timothy Banks +3
This study presents a comprehensive analysis of the detached binary system V570\,Per through combined photometric, spectroscopic, and astrometric observations. By disentangling the…
Empirical Bolometric Correction and Zero-Point Constants of Visual Magnitudes from High-Resolution Spectra
Gökhan Yücel, Selçuk Bilir, Volkan BakıŠ+1
A method of obtaining bolometric corrections () from observed high-resolution, high- spectra is described. The method is applied to spectra of 128 stars collected…
RS Sagittarii: Revealing the component spectra and the mass transfer
Hicran BakıÅ, Ãmrüm Hilal Yıldız, Volkan BakıŠ+1
We present an analysis of high-resolution (R ~ 48000) spectroscopic and photometric data of RS Sgr, a short-period Algol-type binary system. For the first time, precise spectroscop…
Unveiling the Origins and Dynamics of the Hierarchical Triple Star System CN Lyn
G. Yucel, V Bakis, R. Canbay +3
In this study we present a detailed analysis of CN Lyn, an overlooked triple star system, by combining spectroscopic data from the literature, photometric \textit{TESS} data, and k…
