V/99        Cataclysmic Binaries and LMXB Catalogue    (Ritter+ 1998)

Catalogue of cataclysmic binaries, low-mass X-ray binaries and related objects (6th Edition) Ritter H., Kolb U. <Astron. Astrophys. Suppl. Ser. 129, 83 (1998)> =1998A&AS..129...83R
ADC_Keywords: Binaries, cataclysmic ; Binaries, X-ray ; Novae Keywords: catalogues - novae, cataclysmic variables - binaries: close - X-rays: stars Description: Cataclysmic Binaries are semi-detached binaries consisting of a white dwarf or a white dwarf precursor primary and a low-mass secondary which is filling its critical Roche lobe. The secondary is not necessarily unevolved, it may even be a highly evolved star as for example in the case of the AM CVn-type stars. Low-Mass X-Ray Binaries are semi-detached binaries consisting of either a neutron star or a black hole primary, and a low-mass secondary which is filling its critical Roche lobe. Related Objects are detached binaries consisting of either a white dwarf or a white dwarf precursor primary and of a low-mass secondary. The secondary may also be a highly evolved star. The catalogue lists coordinates, apparent magnitudes, orbital parameters, stellar parameters of the components and other characteristic properties of 318 cataclysmic binaries, 47 low-mass X-ray binaries and 49 related objects with known or suspected orbital periods together with a comprehensive selection of the relevant recent literature. In addition the catalogue contains a list of references to published finding charts for 394 of the 414 objects. A cross-reference list of alias object designations concludes the catalogue. Literature published before 30 June 1997 has, as far as possible, been taken into account. This catalogue supersedes the 5th edition (catalogue V/59) and the updated list by Ritter and Kolb (1995; catalogue V/82). File Summary:

Note (1): Wherever possible, the designation of the object given in the General Catalogue of Variable Stars (Cat. II/139) is used here. Note (2): Accuracy written in hexadecimal: A=10", B=11", C=12", D=13", E=14", F=15". If the positional error is larger than 15arcsec, this field is blank Note (3): Object type coarsely characterised using the following abbreviations: AC = AM CVn star, spectrum devoid of hydrogen lines, subtype of NL AM = polar = AM Her system, subtype of NL, contains a synchronously rotating, magnetized white dwarf AS = subtype of AM, with a slowly asynchronously rotating, magnetized white dwarf CP = coherent pulsator, contains a coherently pulsating white dwarf DD = system consists of two degenerate components DN = dwarf nova DQ = DQ Her star, contains a non-synchronously rotating, magnetized white dwarf; usually not seen in X-rays ER = ER UMa star = SU UMa star with an extremely short supercycle IP = intermediate polar, shows coherent X-ray period from a non-synchronously spinning, magnetized white dwarf; usually a strong X-ray source N = classical nova Na = fast nova (decline from max. by 3mag in less than about 100days) Nb = slow nova (decline from max. by 3mag in more than about 100days) Nc = extremely slow nova (typical time scale of the decline from maximum: decades) NL = nova-like variable Nr = recurrent nova SH = non-SU UMa star showing either permanent or transient superhumps SS = supersoft X-ray source; CV with stationary hydrogen burning on the white dwarf SU = SU UMa star, subtype of DN SW = SW Sex star, subtype of NL UG = dwarf nova of either U Gem or SS Cyg subtype UX = UX UMa star, subtype of NL VY = VY Scl star (anti dwarf nova), subtype of NL WZ = WZ Sge star = SU UMa star with an extremely long supercycle ZC = Z Cam star, subtype of DN Note (4): Apparent V magnitude at maximum brightness of: novae (N,Na,Nb,Nc,Nr) in minimum DN (UG,ZC,SU) in minimum NL (UX,AC) in normal state NL (AM,VY) in high state. Note (5): In case of eclipses magnitude at mideclipse, of: novae (N,Na,Nb,Nc,Nr) in minimum DN (UG,ZC,SU) in minimum NL (UX,AC) in normal state NL (AM,VY) in high state. Note (6): Apparent magnitude at maximum brightness of: novae (N,Na,Nb,Nc,Nr) in outburst DN (UG,ZC) in outburst DN (SU) in normal outburst NL (AM,VY) in low state NL (DQ,IP) in flaring state. Note (7): Apparent magnitude of ZC in standstill, SU in superoutburst, at minimum brightness of NL (AM,VY), in low state. Note (8): Time interval between outbursts is defined: - for dwarf novae of subtype UG or ZC: the typical time interval between two subsequent outbursts; - for dwarf novae of subtype SU: T1 is the typical time interval between two subsequent normal outburst, and T2 is the typical time interval between subsequent superoutbursts. Note (9): the * indicates, in case of object type SU, that the orbital period has been estimated from the known superhump period using the empirical relation given by B. Stolz and R. Schoembs (1984A&A...132..187S). Note (10): The second period is, in case of object type: DQ or IP: photometric period if it is different from the spectroscopic one AM: polarization period = spin period of the white dwarf, if it is different from the presumed orbital period (subtype AS) SU: superhump period, wherever possible, at the beginning of a superoutburst SH: photometric period, presumably superhump period of either permanent or transient superhumps Note (11): This additional period is, in case of object type: CP: period of coherent pulsation, (transient if f3._Per=T) DQ: spin period of the white dwarf IP: spin period of the white dwarf, usually detected in X-Rays Note (12): the flag takes the values: ':' uncertainty flag 'T' indicating transient pulsations 'Q' indicating the occurrence of quasi- periodic oscillations (QPO) in objects of type N, DN, NL. Note (13): This additional period is, in case of object type: CP: second period of coherent pulsation, (transient if f4._Per=T) DQ: additional period, presumably due to reprocessed X-Rays IP: additional period, usually seen in the optical and presumably due to reprocessed X-Rays Note (14): The EB flag means: EB= : (blank) no eclipses observed. EB=1: 1 eclipse per orbital revolution observed. EB=2: 2 eclipses per orbital revolution observed. EB=D: periodic eclipse-like dips observed. Note (15): The SB flag means: SB=1: single-line spectroscopic binary SB=2: double-line spectroscopic binary Note (16): Spectral types are given in the following format: [Spectral class/Luminosity class], where the usual roman numerals for the latter are replaced by the corresponding arabic numerals, i.e. I = 1, II = 2, III = 3, IV = 4, V = 5, VI = 6.
