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…
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-V: The First Detailed Light Curve Modeling of Eight Totally Eclipsing Contact Binary Stars Using Ground-Based and TESS Observations
Atila Poro, Raul Michel, Francisco Javier Tamayo +3
This study broadens our comprehensive investigation of total-eclipse W Ursae Majoris-type contact binaries by analyzing eight additional systems, continuing our previous research.…
BSN-IV: The First Multiband Light Curve Study of Five W UMa-type Contact Binary Systems
Atila Poro, Raul Michel, Jean-François Coliac +6
In this work, we present a detailed investigation of five contact binary systems of the W Ursae Majoris (W UMa) type. Multiband photometric observations were conducted using ground…
Pulsating and Non-pulsating Components of Detached Eclipsing Binaries in the Scuti instability strip
Filiz Kahraman AliçavuÅ, Fahri AliçavuÅ, Zeynep Ãelik Orhan +3
Pulsating detached eclipsing binary systems are crucial for studying the internal structure of oscillating stars. These systems are advantageous because binary effects on pulsation…
