M87 has been monitored with a cadence of 5 days over a span of 9 months through the near-ultraviolet (NUV; F275W) and optical (F606W) filters of the Wide Field Camera 3 (WFC3)...

As a result of the next cycle of our long-term monitoring, we present our UBV JHKLM photometry for the symbiotic nova V1016 Cyg in 2008-2014. The star continued to...

The results of BVRI photometric and spectroscopic observations of symbiotic Nova HM Sagittae were made in 1986-2002.

UBVR photometric and spectroscopic observations of V838 Mon during the outbursts.

JHKLM photometry of two symbiotic novae, V1016 Cyg and HM Sge in 1978-1999 is presented.

Continuing the project described by Kato et al. (2009PASJ...61S.395K), we collected times of superhump maxima for 127 SU UMa-type dwarf novae observed mainly during the...

Continuing the project described by Kato et al. (2009PASJ...61S.395K), we collected times of superhump maxima for 128 SU UMa-type dwarf novae observed mainly during the...

We have developed a method for estimating the orbital periods of dwarf novae from the Sloan Digital Sky Survey (SDSS) colors in quiescence using an artificial neural network....

V445 Pup was a peculiar nova having no hydrogen spectral lines in the outburst. The spectrum contained strong emission lines of carbon, oxygen, calcium, sodium and iron. We have...

We obtained extensive new BVRcIc photometry of Nova KT Eri 2009 over a 539-day interval during the post-outburst quiescence, from 30 September 2011 to 22 March 2013 (days +684...

Spatial distribution, galactic model parameters and luminosity function of cataclysmic variables (CVs) in the solar neighbourhood have been found using distances estimated from...

We present our UBVRcIc CCD photometry of a new dwarf nova OT J213806.6+261957 in Pegasus, discovered during its superoutburst on May 6, 2010 and classified as a WZ Sge-type...

We present the UBV(RI)C photometry of a new dwarf nova V466 And, discovered during its superoutburst on Sept. 1.6, 2008 and classified as a WZ Sge-type object. In the first 11...

We present the UBV(RI)c photometry of the dwarf nova Tri 2008 = OT J023839.1+355648 obtained during its superoutburst started on October 25, 2008. The object can be classified...

V392 Persei is a known dwarf nova (DN) that underwent a classical nova eruption in 2018. Here we report ground-based optical, Swift UV and X-ray, and Fermi-LAT {gamma}-ray...

SU UMa stars are characterized by 'superoutbursts', which are brighter at maximum light and which last much longer than the more frequent 'ordinary' outbursts of these dwarf...

We present a comprehensive review of all observations of the eclipsing recurrent Nova LMC 1968 in the Large Magellanic Cloud which was previously observed in eruption in 1968,...

Spiral density waves are thought to be excited in the accretion discs of accreting compact objects, including cataclysmic variable stars (CVs). Observational evidence has been...

We present measurements of the component masses in 15 Cataclysmic Variables (CVs) - 6 new estimates and 9 improved estimates. We provide new calibrations of the relationship...

The BVI light curves of seven recent novae (i.e. V1534 Sco, V1535 Sco, V2949 Oph, V3661 Oph, MASTER OT J010603.18-744715.8, TCP J18102829-2729590 and ASASSN-16ma) have been...
