A likely optical counterpart of the G292.0+1.8 pulsar wind nebula
S. V. Zharikov, Yu. A. Shibanov, D. A. Zyuzin +2
G292.0+1.8 is the Cas A-like supernova remnant containing the young pulsar PSR J1124-5916, which powers a compact torus-like pulsar wind nebula with a jet visible in X-rays. We hav…
High Dispersion Absorption-line Spectroscopy of AE Aqr
J. Echevarria, R. Connon Smith, R. Costero +2
High-dispersion time-resolved spectroscopy of the unique magnetic cataclysmic variable AE Aqr is presented. A radial velocity analysis of the absorption lines yields K_2 = 168.7+/-…
Possible optical detection of a fast, nearby radio pulsar PSR B1133+16
S. V. Zharikov, Yu. A. Shibanov, R. E. Mennickent +1
Aims: We performed deep optical observations of the field of an old, fast-moving radio pulsar PSR B1133+16 in an attempt to detect its optical counterpart and a bow shock nebula. M…
Evidence of Precession of the White Dwarf in Cataclysmic Variables
G. Tovmassian, S. Zharikov, V. Neustroev
Cataclysmic Variables (CV) are close binary systems, in which the primary, the more massive star, is a white dwarf. CVs usually exhibit a number of periodicities, most of which are…
Simultaneous photometry and echelle-spectroscopy of the dwarf nova BZ Ursae Majoris during the 2005 January Outburst
V. V. Neustroev, S. V. Zharikov, R. Michel
We report simultaneous photometric and echelle-spectroscopic observations of the dwarf nova BZ UMa during which we were lucky to catch the system at the onset of an outburst, the d…
Steps towards a solution of the FS Aurigae puzzle. I. Multicolour high-speed photometry with ULTRACAM
V. V. Neustroev, S. V. Zharikov, G. H. Tovmassian +1
We present the analysis of high-speed photometric observations of FS Aur taken with the 4.2-m William Herschel Telescope and the high-speed camera ULTRACAM in late 2003. These obse…
A new two-pole accretion polar: RX J1846.9+5538
R. Schwarz, J. Greiner, G. H. Tovmassian +2
We report the discovery of a new, bright (V = 17 mag) AM Her system as the optical counterpart of the soft ROSAT All-Sky-Survey source RX J1846.9+5538 (= 1RXS J184659.4+553834). Op…
Subaru optical observations of the old pulsar PSR B0950+08
S. V. Zharikov, Yu. A. Shibanov, A. B. Koptsevich +6
We report the B band optical observations of an old (17.5 Myr) radiopulsar PSR B0950+08 obtained with the Suprime-Cam at the Subaru telescope. We detected a faint object, B=27.07(1…
The New AM Her System RX J0704.2+6203. Northern Twin of BL Hyi
G. H. Tovmassian, P. Szkody, J. Greiner +6
We report here on the identification and study of the optical counterpart of the ROSAT source RX J0704.2+6203. Extensive spectral and photometric observation showed that the object…
The new cataclysmic variable RX J1554.2+2721 in the period gap
G. H. Tovmassian, J. Greiner, S. V. Zharikov +2
We report on the results of a spectroscopic and photometric study of a new cataclysmic variable, identified as optical counterpart of the X-ray source RX J1554.2+2721 detected by R…

We present the results of the broad-band photometry of the nearby middle-aged radio pulsar PSR B0656+14 and its neighborhood obtained with the 6-meter telescope of the SAO RAS and…
BVR_cI_c light curves of GRB970508 optical remnant and magnitudes of underlying host galaxy
S. V. Zharikov, V. V. Sokolov
The observations with the SAO-RAS 6-m telescope in July-August 1998 show that the GRB970508 optical remnant has varied very little since November 1997. We can conclude that we obse…

V. V. Sokolov, S. V. Zharikov, Yu. V. Baryshev +5
Late-time observations of GRB970508 with the SAO-RAS 6-m telescope in July-August 1998 show that the optical transient (OT) varies very little since November 1997. Here we report t…
