V994 Her: A Unique Triply Eclipsing Sextuple Star System
P. Zasche, T. Borkovits, R. Jayaraman +23
We report the discovery with of a third set of eclipses from V994 Herculis (TIC 424508303), previously only known as a doubly-eclipsing system. The key implication of this d…
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.…
The Continuing Story of SN IIb 2013df: New Optical and IR Observations and Analysis
Tamás Szalai, József Vinkó, Andrea P. Nagy +17
SN 2013df is a nearby Type IIb supernova that seems to be the spectroscopic twin of the well-known SN 1993J. Previous studies revealed many, but not all interesting properties of t…
Extensive Spectroscopy and Photometry of the Type IIP Supernova 2013ej
G. Dhungana, R. Kehoe, J. Vinko +32
We present extensive optical (, , and open CCD) and near-infrared () photometry for the very nearby Type IIP SN ~2013ej extending from +1 to +461 days after…
Is There a Third Component in the Intermediate Polar V405 Aur?
Vitalii V. Breus, Ivan L. Andronov, Pavol Dubovsky +10
Variability of the spin period of the white dwarf in the V405 Aur (RX J0558.0+5353) system using our observations and previously published maxima timings is analyzed. As the phase…
Variability of the Spin Period of the White Dwarf in the Intermediate Polar V405 Aur: Low-Mass Third Body or Precession ?
V. V. Breus, I. L. Andronov, P. Dubovsky +9
We present the results of photometric CCD observations of the magnetic cataclysmic variable V405 Aurigae (RX J0558.0+5353 = 1RXS J055800.7+535358) obtained using different instrume…
Period variations the intermediate polars EX Hya, FO Aqr and RXS J180340.0+401214
Vitalii V. Breus, Ivan L. Andronov, Tibor Hegedus +4
We present results of CCD photometric study of the intermediate polars FO Aqr, EX Hya and RXS J180340.0+401214 = USNO-A2.0 1275-09738647 and corresponding corrected ephemerids.
