The Early Light Curve of a Type Ia Supernova 2021hpr in NGC 3147: Progenitor Constraints with the Companion Interaction Model
Gu Lim, Myungshin Im, Gregory S. H. Paek +19
The progenitor system of Type Ia supernovae (SNe Ia) is expected to be a close binary system of a carbon/oxygen white dwarf (WD) and a non-degenerate star or another WD. Here, we p…
Unusual Hard X-ray Flares Caught in NICER Monitoring of the Binary Supermassive Black Hole Candidate AT2019cuk/Tick Tock/SDSS J1430+2303
Megan Masterson, Erin Kara, Dheeraj R. Pasham +17
The nuclear transient AT2019cuk/Tick Tock/SDSS J1430+2303 has been suggested to harbor a supermassive black hole (SMBH) binary near coalescence. We report results from high-cadence…
Poorly Studied Eclipsing Binaries in the Field of DO Dra: V0455 Dra and V0454 Dra
Yonggi Kim, Ivan L. Andronov, Kateryna D. Andrych +3
We report an analysis of two poorly studied systems GSC 04396-00605 and GSC 04395-00485, which were recently named as V0455 Dra and V0454 Dra, respectively. For two eclipsing stars…
Instabilities in Interacting Binary Stars
Ivan L. Andronov, K. D. Andrych, K. A. Antoniuk +43
The types of instability in the interacting binary stars are reviewed. The project "Inter-Longitude Astronomy" is a series of smaller projects on concrete stars or groups of stars.…
Newly Discovered Eclipsing Binary 2MASS J18024395+4003309 (VSX J180243.9+400331):Two-Color Photometry vs Phenomenological Modeling
Ivan L. Andronov, Yonggi Kim, Young-Hee Kim +3
We report on analysis of the two-color VR CCD observations of the newly discovered variable 2MASS J18024395+4003309=VSX J180243.9+400331 obtained using the 1-m telescope of the Mt.…
Idling Magnetic White Dwarf in the Synchronizing Polar BY Cam. The Noah-2 Project
Ivan L. Andronov, Kirill A. Antoniuk, Vitalii V. Breus +8
Results of a multi-color study of the variability of the magnetic cataclysmic variable BY Cam are presented. The observations were obtained at the Korean 1.8m and Ukrainian 2.6m, 1…
