High-Resolution Spectroscopy of Long-Periodic Eclipsing Binary Epsilon Aurigae
Alex Golovin, Yuliana Kuznyetsova, Maxim Andreev
The results of spectroscopic observations of long-periodic eclipsing binary Epsilon Aur are reported. The observations were carried out during 2 nights in 2007 at 2-meter telescope…
RZ Cassiopeia: Eclipsing Binary with Pulsating Component
A. Golovin, E. Pavlenko
We report time-resolved VR-band CCD photometry of the eclipsing binary RZ Cas obtained with 38-cm Cassegrain telescope at the Crimean Astrophysical Observatory during July 2004 - O…
Discovery of The New WZ Sge Star, SDSS J080434.20+510349.2
E. Pavlenko, S. Yu. Shugarov, N. A. Katysheva +13
We present the results of photometric observations of SDSS J080434.20+510349.2 in its low state and during an outburst and spectroscopy during the outburst. We found such peculiari…
Monitoring of FR Cnc Flaring Activity
A. Golovin, M. Andreev, E. Pavlenko +3
Being excited by the detection of the first ever-observed optical flare in FR Cnc, we decided to continue photometrical monitoring of this object. The observations were carried out…
SDSS J102146.44+234926.3: New WZ Sge-type dwarf nova
Alex Golovin, Ayani Kazuya, Pavlenko Elena P. +10
We report CCD photometry and spectroscopy during 2006 outburst of the dwarf nova SDSS J102146.44+234926.3 (SDSS J1021). The photographic plates from the MAO, SAI and CrAO plate arc…
Detection of a Large Flare in FR Cnc (=1RXS J083230.9+154940)
Alex Golovin, Elena Pavlenko, Yuliana Kuznyetsova +1
We report detection of an optical flare in the BY Draconis type star FR Cnc. The flare duration is 41 min, the amplitude is in the B band 1.02 m. It is the first flare reported for…
