  • Asteroid phase curve coefficients from ATLAS observations

    Asteroid phase curves are used to derive fundamental physical properties through the determination of the absolute magnitude H. The upcoming visible Legacy Survey of Space and...
  • Classical Cepheids BVIc observations

    In 2013-2014, we obtained 14959 CCD frames in the BVIc photometric system for 170 classical Cepheids from the General Catalogue of Variable Stars. We performed our observations...
  • BVI_c_ light curves of 57 Cepheids

    In 2008-2013, we obtained 11333 CCD BV Ic frames for 57 Cepheids from the General Catalogue of Variable Stars. We performed our observations with the 76-cm telescope of the...
  • Fast optical variability of SS 433

    We study the variability of the optical flux from the peculiar Galactic source SS 433 based on observations with the Russian-Turkish 1.5-m telescope. We describe in detail the...
  • NGC 6866 proper motions and CCD photometry

    We present the results of our comprehensive study of the Galactic open star cluster NGC 6866. The positions of stars in the investigated region have been obtained with the...
  • Optical Variabilities in 3C 120

    Based on our UBVRI observations and X-ray data from the RXTE satellite we have investigated the variabilities of the Seyfert Galaxy 3C 120 over the period 1996-2008.
  • Observations of supernovae in 1997-1999

    Photometric observations of 15 supernovae discovered in the period 1997-1999 are presented. Cone search capability for table J/PAZh/30/37/table1 (Main data on the supernovae and...
  • BV(RI)c-JHK photometry of BL Lac in 1999-2001

    Results of multicolor observations of BL Lac in 1999-2001 are presented. We show that the spectral energy distribution of the variable component in the range from K to B had...
  • BVR photometry of NGC 6584

    Automatic stellar photographic BVR photometry reaching 1mag below the horizontal branch of NGC 6584, located at V~16.5mag, has been performed for this poorly studied globular...
  • The open cluster NGC 346

    We present CCD photometry and spectrographic observations for stars in the open cluster NGC 346, which excites the largest H II region in the Small Magellanic Cloud. These...
  • BVR CCD photometry on NGC 1777

    We present photographic (B and V) and CCD (B, V, and R) photometry of stars in the remote LMC cluster NGC 1777, and integrated UBV photometry of the inner part of the cluster. A...
  • Times of maxima for 23 delta Scuti stars

    The multi-color CCD photometric study of 27 delta Scuti stars is presented. By using approximately three years of photometric observations, we obtained the times of maxima and...
  • CCD photometry of NGC 2482

    We present BV and u'g'r'i' CCD photometry of the central region of NGC 2482. We also present BVu'g' CCD photometry of five clusters that have been poorly studied in the past:...
  • Times of Maxima for the SX Phe star BL Cam

    A total of 73 new times of maximum light for BL Cam were observed through the years 2005 to 2011, which are combined with 1392 times of maxima taken from literature. A more...
  • Time of Maxima for the SX Phe star XX Cyg

    XX Cyg is a High Amplitude {delta} Scuti star which has been extensively studied because of its changing period. We present 64 new times of maxima which have been combined with...
  • UBVI_KC_ photometry in NGC 2309

    We have obtained CCD UBVI_KC_ photometry down to V~22.0 for the open cluster NGC 2309 and its surrounding field. Twenty three probable cluster members have been identified for...
  • BVR light curves of BX Peg

    We present the results of new CCD photometry for the contact binary BX Peg, made during three successive months beginning on 2008 September. As do historical light curves, our...
  • Periodic variables in NGC 2301

    We present the results of a search for periodic variables within 4078 time-series light curves and an analysis of the period-color plane for stars in the field of the open...
  • BVRI differential photometry of GW Gem

    New multiband CCD photometry is presented for the eclipsing binary GW Gem; the RI light curves are the first ever compiled. Four new minimum timings have been determined. Our...
  • NGC 6318 CCD BVI photometry

    We present CCD BVI photometry for the southern open cluster NGC 6318. The sample consists of 9876 stars measured in an area of 13.6'x13.6', extending down to V~21.5mag. Star...
