Orbital and stellar parameter determination of eclipsing Cep pulsators
C. I. Eze, G. Handler, F. Kahraman Aliçavuş +2
Eclipsing binaries provide precise constraints on stellar properties and evolution, making those hosting Cep pulsators particularly valuable for characterising massive pulsatin…
BSN-VII: Photometric Light Curve Study of Three Cool, Large-Amplitude, Low Mass, W-Subtype Contact Binaries
Atila Poro, Raul Michel, Diana Zadkhosh +9
We present a comprehensive photometric study of three W UMa-type contact binary systems, V1104 Her, V1284 Her, and V2822 Ori, based on a combination of ground-based observations an…
Multivariate Statistical Analysis of Low Mass Ratio Contact Binaries: Definition, Dynamical Stability, and Parameter Relationships
A. Poro, R. Poggiani, A. Foroutanfar +3
This study explores multiple aspects of W Ursae Majoris (W UMa) contact binary systems with low mass ratios, providing empirical insights into their definition, structure, rotation…
Spectral and timing variability of the transient ultraluminous X-ray source NGC 4631 X-4
Sinan Allak, Wei Yu, Lorenzo Ducci +4
Ultraluminous X-ray sources (ULXs) are among the best laboratories for studying super-Eddington accretion onto compact objects. We present a detailed spectral and timing analysis o…
A candidate cyclotron line at 1.89 keV in the ultraluminous X-ray source NGC 4861 X-2
Sinan Allak, Lorenzo Ducci, Valery F. Suleimanov +6
In this Letter, we report the detection of an absorption-like feature at ~1.89 keV in Chandra/ACIS spectra of the ultraluminous X-ray source NGC 4861 X-2, based on the deepest obse…
IZ Tel and UW Vir: Southern oscillating eclipsing Algol systems with active mass transfer
Alexios Liakos, David J. W. Moriarty, Julian F. West +1
This study is an in-depth examination of IZ Tel and UW Vir which are semi-detached oscillating Eclipsing Algol binary systems (oEA stars). The radial velocities of both components…
