The AH Pictoris Syndrome: Continuous Trains of Stunted Outbursts in Novalike Variables
The Astrophysical JournalNovalike variables are a subgroup of cataclysmic variables (CVs) that—unlike dwarf novae—do not exhibit strong brightenings in their long-term light curves.

”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 ...

TESS Light Curves of Cataclysmic Variables. V. Improved or Corrected Orbital Periods of 53 Systems
The Astronomical JournalThe long and continuous high-time-resolution coverage of many stars by the Kepler and TESS space missions permit to explore periodic phenomena with a much higher precision than is possible with terrestrial observations.

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

Period–Luminosity Relations for Double-mode δ Sct Stars
The Astrophysical JournalPrevious studies of the period–luminosity relations (PLRs) of Delta Scuti ( δ Sct) stars have focused on those with a single pulsation mode. However, for δ Sct stars with many different pulsation modes, classifying a single mode is difficult.

Classification of variable stars in the WFCAM Transit Survey
EPJ Web of Conferences, 2013 The WFCAM Transit Survey is a photometric survey in the near-infrared and aims at finding Earth-like planets transiting M-dwarf stars. As a by-product of the survey, a variety of variable stars has been detected.

Stellar Variability toward the Galactic Open Cluster NGC 7209
The Astrophysical JournalWe present the analysis of stellar variability in an open cluster NGC 7209 using optical V -band CCD photometric observations. Out of 4499 stars in our study, we detected 284 candidate variables, including one identified previously.
