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…
Detailed Investigation of a W UMa Contact Binary with an Ultralow Mass Ratio and a Third-Body as a Potential Merger Candidate
Atila Poro, Ehsan Paki, Fahri Alicavus +1
The lower limit of the mass ratio in contact binaries remains uncertain, with observations suggesting systems exist below theoretical predictions. The stability of such very low ma…
BSN-VI: Multiband Light Curve Modeling of Four W UMa-Type Contact Binaries I. Revisiting Energy Transfer Mechanisms and Luminosity Behavior
Elham Sarvari, Atila Poro, Raul Michel +5
We presented the first high-precision, detailed photometric analysis of four W Ursae Majoris (W UMa)-type contact binaries, Linear 10772300, Linear 11150338, Linear 20372537 and DM…
Detailed TESS-Based Light Curve Modeling and Fundamental Parameter Estimation of 27 W UMa-Type Contact Binaries
Atila Poro, Ahmad Sarostad, Mohammad Davoudi +30
We performed a comprehensive analysis of 27 short period contact binary systems for which no light curve analysis had previously been reported. Photometric time-series data from th…
BSN: Light Curve Modeling and Orbital Evolution of the Total-Eclipse Contact Binary EZ Oct
Asma Ababafi, Atila Poro, Mehmet Tanriver +1
We present the first detailed multiband (BVR_cI_c and TESS) photometric analysis of the short-period binary EZ Oct. This study combines ground-based observations conducted at a Sou…
BSN: The First Multiband Light Curve Analysis of the W UMa-type Contact Binary System EM Tucanae
Sepideh Houshiar, Atila Poro, Abbas Abedini +1
We present a comprehensive photometric light curve and orbital period analysis of the W UMa-type contact binary EM Tuc. The O-C analysis constructed from all available eclipse timi…
