J/AcA/48/35   All Sky Automated Survey variable stars (Pojmamski 1998)

The All Sky Automated Survey. The catalogue of the periodic variables stars in the Selected Fields. Pojmanski G. <Acta Astron., 48, 35 (1998)> =1998AcA....48...35P
ADC_Keywords: Stars, variable ; Surveys ; Photometry Keywords: Catalogs - stars: variables - surveys Abstract: Results of the first two months of observations using the All Sky Survey prototype camera are presented. More than 45000 stars in 24 Selected Fields covering 140 square degrees were monitored a few times per night resulting in the I-band catalog containing 107 individual measurements. Period search revealed 126 variable stars brighter than 13mag with periods less than 20d. Only 30 of them are known variable stars included in the General Catalogue of Variable Stars (II/214). The other 90 objects are newly detected variable stars - mainly eclipsing binaries (75%) and pulsating stars (17%). We estimate that completeness of the current catalogs of variable stars is smaller than 50% already for the stars brighter than 9mag. The catalog is accessible over the WWW: File Summary:

Note on ASAS: The designation is based on J2000 position; the "134460-3019.2" name was changed to "134500-3019.2"Note on Type: Note on Type: ACV: α2 CVn type CEP(B): Cepheid B type DCEP: Delta Cep type DCEPS: Delta Cep type DSCT: Delta Scuti type EA: Algol type EB: Eclipsing binary EW: W UMa type MISC: Miscellaneous RRab: RRab Lyrae type RRc: RRc Lyrae type Note on CrossId: The cross-identification of ASAS J114736-6310.4 and 114736-6322.7 are flagged with an '*', they have been corrected at CDS (see the "History" section below)
History: * 15-Jun-1998 Copied from * 14-Jan-1999 Corrected the CKS identifications for 114736-6310.4 and 114736-6322.7, after discussion with Grzegorz Pojmanski: "I misplaced "OtherID" for the two adjacent lines (in Table 3)" and therefore the cross-identifications are: ASAS J114736-6310.4 = CKS91 11451-6253 ASAS J114736-6322.7 = CKS91 11451-6305 = HD 309036
