HST imaging and light curves of 21 SPIRITS variables
The SPitzer InfraRed Intensive Transients Survey (SPIRITS) searched for luminous infrared (IR) transients and variables in nearly 200 nearby galaxies from 2014 to 2019, using... -
Cepheid Metallicity in the Leavitt Law Survey
The highly debated effect of metallicity on the absolute magnitudes of classical Cepheid variables needs to be properly quantified for determining accurate and precise distances... -
Variable Stars in Local Group Galaxies. VI.
We present the discovery of variable stars in two isolated dwarf galaxies in the outskirts of the Local Group, VV 124 and KKr 25, using observations with the Hubble Space... -
Classifier catalogue of class II YSO posteriors
A naive Bayes classifier for identifying Class II YSOs has been constructed and applied to a region of the Northern Galactic Plane containing 8 million sources with good quality... -

AI CMi UBV light curves
The U BV photometry and low-resolution spectroscopy for the semiregular variable AI CMi, a candidate for post-AGB objects, performed in 1996-2016 and 2000-2013, respectively,... -
V1027 Cygni UBV and JHKLM photometry
We present the results of our UBV and JHKLM photometry for the semiregular pulsating variable V1027 Cyg, a supergiant with an infrared excess, over the period from 1997 to 2015... -
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... -
V1329 Cyg UBV light curves and spectrum
The photoelectric UBV observations of the peculiar symbiotic star V1329 Cyg performed at the Crimean Station of the SAI-MSU during 245 nights over the period 2003-2014 are... -
U Sgr BV light curves
For the classical Cepheid U Sgr, we have constructed an O-C diagram spanning a time interval of 144 years. The O-C diagram has the shape of a parabola, which has made it... -
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... -
Galactic classical Cepheids properties
Based on our compiled catalogue of positions, velocities, ages, and abundances of nine chemical elements for 221 classical Cepheids, we analyze the dependences of the relative... -
1RXS J073346.0+261933 light curve
In the course of our search for the optical identifications of ROSAT X-ray sources, we have found a highly variable object with a very unusual behavior on long time scales, rare...
