Abstract
We study the newly discovered variable star GSC 4560–02157. CCD photom-etry was performed in 2013–2014, and a spectrum was obtained with the 6-m telescopein June, 2014. GSC 4560–02157 is demonstrated to be a short-period ( P = 0 . d )eclipsing variable star. All its flat-bottom primary minima are approximately at the samebrightness level, while the star’s out-of-eclipse brightness and brightness at secondaryminimum varies considerably (by up to . m ) from cycle to cycle. Besides, there areshort-term (time scale of 0.03–0.04 days) small-amplitude brightness variations out ofeclipse. This behavior suggests cataclysmic nature of the star, confirmed with a spectrumtaken on June 5, 2014. The spectrum shows numerous emissions of the hydrogen Balmerseries, HeI, HeII. Key words: stars: dwarf novae – binaries: eclipsing – stars: individual: GSC 4560–02157
Among short-period spectroscopic and eclipsing binaries, cataclysmic stars are of special interest. Thesesystems contain a white dwarf and an ordinary dwarf, yellow or red, which donors matter to the Rochelobe of the white dwarf. Matter flows, accretion disks, hot spots (or hot lines) at the interaction betweenthe flow and the disk, all cause complicated light variability, e.g., changing brightness levels at differentactivity states, outbursts, quasi-periodic variations, humps on the light curve, etc. For a general reviewof cataclysmic variable stars, see Warner 1995.In this paper, we present the discovery and study of the new variable star GSC 4560–02157. Itis shown to be a short-period eclipsing variable star exhibiting, outside its primary minima, strongvariations of the brightness level, with superimposed short-term brightness variations. The cataclysmicnature of the new variable could be confirmed with its spectrum taken with the 6-meter telescope of theSpecial Astrophysical Observatory.
Variability of GSC 4560–02157 was suspected by one of the authors (A.V. Khruslov) in2005 from the publicly available data of the Northern Sky Variability Survey (NSVS;

The star is in ′′ from GSC 4560–02269,and NSVS data refer to a blend of the two stars. In March 2013 (JD 2456364), we started CCD photom-etry of the two stars in order to establish which of them varies.The actual variable star is GSC 4560–02157 ( h m . s , +75 ◦ ′ . ′′ , J2000.0 in the 2MASSPoint Source Catalog, Skrutskie et al. 2006).Our CCD observations in the Johnson R and V bands were performed at the Tien ShanAstronomical Observatory of the V.G. Fesenkov Astrophysical Institute, at the altitude of 2750 m abovethe sea level. The observatory has two Zeiss 1000-mm telescopes. Most of our observations were per-formed with the eastern Zeiss 1000-mm reflector (the focal length of the system was 6650 mm, the de-tector being an Apogee U9000 D9 CCD camera). During the three last nights (JD 2456772–2456784),we used the newly introduced western Zeiss 1000-mm reflector (the focal length of the system was13250 mm, the detector being an Apogee F16M CCD camera). In the R band, we obtained 2455brightness measurements (JD 2456364–2456784), and in the V band, 828 measurements (JD 2456739–2456784). We performed reductions using the MaxIm DL aperture photometry package.The total range of the star’s brightness variations is between 14.40 m and 15.53 m R , 14.75 m and16.10 m V .Table 1, available in its complete form in the electronic supplement to this paper, contains ourphotometric observations. Here we present its first lines (photometry in each of the colors) for guidanceconcerning its format.The finding chart (Fig. 1) identifies the variable star, comparison star, and check star. The com-parison star was GSC 4560–01221 ( h m . s , +75 ◦ ′ . ′′ , J2000.0), and the check star, GSC4560–01352 ( h m . s , +75 ◦ ′ . ′′ , J2000.0). The magnitudes of the comparison star in theGSC2.3 catalog (Lasker et al. 2008) are R = 14 . and V = 14 . . We analyzed the time series using the Lafler–Kinman method (Lafler & Kinman 1965) implemented inthe WinEfk code developed by one of the authors (V.P.G.). GSC 4560–02157 is found to be an Algol-type eclipsing binary with a short period (about 0.265 days) and considerable brightness variationsoutside the primary eclipse, which remains at approximately the same magnitude for all the observedcycles. The star’s brightness outside the primary eclipse slowly changes its level between different or-bital cycles by as much as . m − . m ; small short-term brightness variations are superimposed. Inany individual cycle, the star is redder in the primary minimum than outside it. The ephemeris for theprimary eclipses is: HJD(min) = 2456719 .

The finding chart, with the variable, its close neighbor, comparison star, and check starmarkedthe secondary minimum varies with general changes of the brightness level outside the primary eclipse.The light curve folded with the orbital period is displayed in Fig. 2.For comparison, Fig. 3 shows the light curve of the known dwarf nova GY Cnc, folded with itsorbital period, . d (Feline et al. 2005). The observations we use are those available fromthe Catalina Surveys (Drake et al. 2009). The scattered bright data points correspond to dwarf-novaoutbursts. The period of the binary GY Cnc is somewhat shorter than that of GSC 4560–02157, andno outbursts of GSC 4560–02157 have been detected so far, but the general character of the eclipsinglight curves is very similar for the two stars. The spectrum of GY Cnc reproduced in Szkody et al. 2009resembles that of GSC 4560–02157 very strongly.Individual cycles outside the primary eclipse reveal small-amplitude short-period brightness varia-tions (Fig. 4). To study them, we analyzed the more complete 2014 R -band data. Observations duringprimary eclipses were excluded, and the remaining data were reduced to the same brightness level, thuseliminating comparatively slow outside-eclipse brightness level variations. The total of 1637 bright-ness estimates obtained in this way (JD 2456716–2456784) were subject to frequency analysis usingDeeming’s method (Deeming 1975). A part of the power spectrum is shown in Fig. 5. Table 2 lists thesix most prominent frequencies. These variations had the largest amplitude (up to . m ) on the lastnight, JD 2456784. A. V.

The computed heliocentric correction was ∆ V r = − . km/s. Theradial velocity of the star is nearly zero. The spectrum (Fig. 6) reveals strong emission lines of the Balmerseries. HeI and HeII emissions are also clearly seen. The right side of the spectrogram shows infraredinterference fringes, typical of CCD spectroscopy. Also present are features of interstellar sodium andterrestrial water. The spectrogram definitely confirms that GSC 4560–02157 belongs to cataclysmicvariables. Note that the spectrum was taken at the phase 0.505 of the above light elements for theeclipsing variations, and thus at approximately the secondary minimum. The V -band magnitudes of thestar measured just before the spectrogram, on JD 2456814.4395 and JD 2456814.4402, are 15.676 and15.627. Thus, the star was rather faint in the corresponding secondary minimum.No X-ray source has so far been detected at the position of GSC 4560–2157, but this is no wonderfor a faint and apparently distant star. The data we have accumulated for GSC 4560–02157 clearly identify it as a cataclysmic eclipsing sys-tem. The Algol-type light curve exhibits rapid start of the eclipse; the time from the beginning of theeclipse to the onset of the totality phase is about 15 minutes. Thus, the eclipsed element of the system israther compact. The star’s brightness is nearly constant during the primary minimum, indicating that itis the eclipsed compact element that is responsible for different brightness in different orbital cycles andfor multiperiodic short-term variations. The latter could be pulsations of the white dwarf. The 0.04-daypulsation period is rather large for pulsating white dwarfs (ZZ Ceti variables), but variables with sucha behavior are known, and some authors (e.g., Hermes et al. 2013) suggest a new type of extremelylow-mass (ELM) white dwarfs. In our case, several oscillations are clearly present, but their stabilityis not beyond doubt; they can turn our to be quasi-periodic oscillations, for example, like those notedfor MT Draconis (Zubareva et al. 2011). The changing brightness level outside eclipses is apparentlyrelated to the brightest, central parts of the accretion disk, also occulted in primary eclipses.

The results of our photometric and spectroscopic observations definitely show that GSC 4560–02157 isa new eclipsing cataclysmic variable. So far, no outbursts have been detected for the star, though it re-sembles known eclipsing dwarf novae both photometrically and spectroscopically. Further observationsare needed to reveal possible additional manifestations of the star’s cataclysmic activity, like outbursts,high and low states.
