Diffuse and specular brightness models applied to LEO satellites. Case study: The ONEWEB constellation
María Romero-Colmenares, Katherine Vieira, Jeremy Tregloan-Reed +11
Context. To better understand the observed brightness of low Earth orbit satellites, we must characterize their reflectivity, which in turn depends importantly on their bus designs…
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…
Optical observations of NEA 3200 Phaethon (1983 TB) during the 2017 apparition
Myung-Jin Kim, Hee-Jae Lee, Sang-Min Lee +24
The near-Earth asteroid 3200 Phaethon (1983 TB) is an attractive object not only from a scientific viewpoint but also because of JAXA's DESTINY+ target. The rotational lightcurve a…
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.…
