An X-Ray-dim “Isolated” Neutron Star in a Binary?
The Astrophysical Journal Letters, 2023 We report the discovery of a dark companion to 2MASS J15274848+3536572 with an orbital period of 6.14 hr. Combining the radial velocity from LAMOST observations and modeling of the multiband light curve, one obtains a mass function of ≃0.131 M _⊙ , an ...

ABOUT THREE CATACLYSMIC VARIABLE STARS
Odessa Astronomical Publications, 2017 In order to detect the new outbursts of the three cataclysmic variable TV Crv, NSV 1775, NSV 895, their positions was scanned on the plates of the Odessa collection of the sky service obtained for the period 1958 - 1988. The new outbursts were detected

DETERMINATION OF SIZE OF THE EMITTING REGION IN ECLIPSING CATACLYSMIC VARIABLE STARS
Odessa Astronomical Publications, 2014 The dependencies of the phase of eclipse of the white dwarf’s centre and the durations of the ascending and descending branches of the light curve on the binary system’s parameters were computed using the spherically symmetric approximation and the more ...

CCD-PHOTOMETRY OF CATACLYSMIC VARIABLE ES DRA IN 2001
Odessa Astronomical Publications, 2017 On the base of our 34-day photometry of ES Dra we found its ∼ 20 d light variations with amplitude of 1m.6 and suggest this star could belong to the nova-like subclass of cataclysmic variable stars.

”ASYMPTOTIC PARABOLA” FITS FOR SMOOTHING GENERALLY ASYMMETRIC LIGHT CURVES
Odessa Astronomical Publications, 2016 A computer program is introduced, which allows to determine statistically optimal approximation using the "Asymptotic Parabola" fit, or, in other words, the spline consisting of polynomials of order 1,2,1, or two lines ("asymptotes") connected with a ...
