AT 2025abao light curves
We present photometric and spectroscopic observations of the luminous red nova (LRN) AT 2025abao, the fourth discovered in M 31. The LRN, associated with the AGB star... -
Nova Vul 2024 (V615 Vul) spectra
Among galactic novae, many remain poorly characterized due to heterogeneous data, observational challenges, or heavy reddening along the Galactic plane. A detailed... -
Photometric monitoring of novalike CVs
A program of long-term ground-based photometric monitoring of 134 old novae and novalike cataclysmic variables (CVs) has been concluded. In this paper, we display, analyze, and... -
BVRI and fluxes of HM Sge in 1986-2000
The results of BVRI photometric and spectroscopic observations of symbiotic Nova HM Sagittae were made in 1986-2002. -
UBVR photometry of Nova Mon 2002 (V838 Mon)
UBVR photometric and spectroscopic observations of V838 Mon during the outbursts. -
IR photometry of V1016 Cyg and HM Sge
JHKLM photometry of two symbiotic novae, V1016 Cyg and HM Sge in 1978-1999 is presented. -
Seven recent novae BVI light curves
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... -
SS Cyg rapid radio flaring in 2016
The connection between accretion and jet production in accreting white dwarf binary systems, especially dwarf novae, is not well understood. Radio wavelengths provide key... -
Blobs in AT Cnc
The Z Cam-type dwarf nova AT Cancri (AT Cnc) displays a classical nova (CN) shell, demonstrating that mass transfer in cataclysmic binaries decreases substantially after a CN... -
Symbiotic recurrent nova T CrB spectroscopy
T CrB is a symbiotic recurrent nova known to exhibit active phases, characterized by apparent increases in the hot component temperature and the appearance of flickering, i.e.... -
Dwarf novae outbursts properties
We present a statistical study of all measurable photometric features of a large sample of dwarf novae during their outbursts and superoutbursts. We used all accessible... -
BVRI light curves of Nova V723 Cas
We present optical spectroscopy collected at seven epochs and BVRcIc photometry obtained at 1227 epochs of nova V723 Cas, covering the time interval between 2007 and 2015. The... -
Optical photometry of nova V5588 Sgr
The outburst of Nova Sgr 2011 N.2 (=V5588 Sgr) was followed with optical and near-IR photometric and spectroscopic observations for 3.5 yr, beginning shortly before the maximum.... -
Nova Mon 2012 BV(RI)c light curves
We present and discuss accurate and densely mapped BVR_C_I_C_ light curves of the neon Nova Mon 2012, supplemented by the evolution in Stromgren b and y bands and in the... -
New Dwarf novae in SDSS, GALEX and astrom. cat.
By cross-matching blue objects from the Sloan Digital Sky Survey with Galaxy Evolution Explorer and the astrometric catalogues USNO-B1.0, GSC2.3 and CMC14, 64 new dwarf nova... -
Light curves of V838 Mon and V4332 Sgr
We analyze spectra of V838 Mon and V4332 Sgr taken in 2004-2005 using the 6m telescope of the Special Astrophysical Observatory with the UAGS and SCORPIO spectrographs. We... -
UBVJHKLM Photometry of Nova Cygni 1992
The results of photometric UBVJHKLM observations of Nova Cygni 1992 performed from the 83d until the 290th day after the nova outburst are presented. The accuracy of the... -
Cataclysmic variables from LAMOST DR6
In this work, we present a catalog of cataclysmic variables (CVs) identified from the sixth data release (DR6) of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope... -
Five decades 1-40GHz obs. of 36 classical novae
We present radio observations (1-40GHz) for 36 classical novae, representing data from over five decades compiled from the literature, telescope archives, and our own programs.... -
HST survey for novae in M87. I. VI LCs
The Hubble Space Telescope has imaged the central part of M87 over a 10 week span, leading to the discovery of 32 classical novae (CNe) and nine fainter, likely very slow,...
