WebWyrzykowski et al. 2004; the Northern Sky Variability Survey (NSVS), Otero et al. 2004), the sample size grew rapidly to about 15,000. Paczyńskietal.(2006) then almost doubled the number by identifying and classifying 11,076 EBs from the All Sky Automated Survey (ASAS). The work from Paczyńskietal. Webthe past two years we have searched for candidate low-mass binaries in the Northern Sky Variability Survey (NSVS) database (Wozniak et al. 2004). Our search algorithm uses two period-searching methods: the “string/rope” method based on the Lafler-Kinman statistic (Clarke 2002), and the analysis of variance method (Schwarzenberg-Czerny 1989).

WebWe have classified 409 objects in the Northern Sky Variability Survey (NSVS) as new β Lyrae or Algol-type eclipsing binaries. These candidates have outside of eclipse magnitudes of ∼10–13. Through automated Fourier analysis routines and some manual inspection, we list the period, eclipse depths, coordinates, an estimate of the time of primary eclipse, … WebWe present a catalog of 8678 slowly varying stars with near-infrared colors corresponding to the evolved asymptotic giant branch population. Objects were selected from the Northern Sky Variability Survey (NSVS) covering the entire sky above declination δ=-38deg in a single unfiltered photometric band corresponding to a V-band …
WebWe have identified 4659 variable objects in the Northern Sky Variability Survey. We have classified each of these objects into one of the five variable star classes: (1) Algol/β Lyr systems including semidetached, and detached eclipsing binaries, (2) W Ursae Majoris overcontact and ellipsoidal variables, (3) long-period variables such as Cepheid and Mira … Weberrors for any survey. We compared and combinedour results with those given in Northern Sky Variability Survey (NSVS) database, and obtained firm candidates for variability. By such an approach it will be possible to conduct investigations of variability for large numbers of objects.
