RITTERRBIN - Ritter Binaries Related to CVs Catalog (7th Edition, Rev. 7.16)

Overview

This HEASARC database table contains information on the so-called "Related Objects" only, as taken from the Catalog of Cataclysmic Binaries, Low-Mass X-ray Binaries, and Related Objects (7th Edition, rev. 7.16, September 2011) of Ritter & Kolb. The complete catalog lists coordinates, apparent magnitudes, orbital parameters, stellar parameters of the components, and other characteristic properties of 926 cataclysmic binaries, 98 low-mass X-ray binaries, and 359 related objects with known or suspected orbital periods. The HEASARC has for simplicity split this catalog into 3 Browse database tables, one for each class of objects: the present table (RITTERRBIN) containing the related binaries' data, a second one (RITTERCV) containing cataclysmic binaries' data, and a third one (RITTERLMXB) containing the low-mass X-ray binaries' data. The literature published before 1 July 2011 has, as far as possible, been taken into account.

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.

Provenance

This table was last updated by the HEASARC in November 2011 on the pcbdata.dat file from the CDS Catalog B/cb.

Parameters

Name
The name of the related object. Wherever possible, the designation of the object given in the General Catalogue of Variable Stars (GCVS) is used.

Alt_Name
A frequently used alternative name of the related binary.

RA
The Right Ascension in the specified equinox. The RA was given in the J2000 equinox in the originating table, to a precision of 0.1 seconds.

Dec
The Declination in the specified equinox. The declination was given in the J2000 equinox in the originating table, to a precision of 1 arcsecond.

LII
The Galactic Longitude of the object.

BII
The Galactic Latitude of the object.

Acc_Pos
The estimated accuracy of the position in arcseconds. If the positional error is larger than 9 arcseconds, this field is left blank. The letter 'P' indicates an object with a large proper motion.

Type1
The object type as coarsely characterized using the following abbreviations: 

       CP = coherent pulsator, contains a coherently pulsating white dwarf or
            subdwarf
       DD = system consists of two degenerate components
       DS = detached system
       EC = contains a pulsating sdB star of the EC 14026-2647 type
       GC = source in a globular cluster
       GP = sdB-star with g-mode pulsations
       GW = contains a pulsating white dwarf of the GW Vir = PG 1159-035 type
       PN = central star of a planetary nebula
       RS = system shows RS CVn-like chromospheric activity
       SC = sub-stellar companion

Type1_Flag
An uncertainty flag ('?') for the object type parameter Type1.

Type2
The object type as coarsely characterized using the same abbreviations as for the parameter Type1.

Type2_Flag
An uncertainty flag ('?') for the object type parameter Type2.

Type3
The object type as coarsely characterized using the same abbreviations as for the parameter Type1.

Type3_Flag
An uncertainty flag ('?') for the object type parameter Type3.

Type4
The object type as coarsely characterized using the same abbreviations as for the parameter Type1.

Mag1
The apparent V (or other, if so specified) magnitude at maximum brightness outside an eclipse.

Mag1_Flag
This can be either an uncertainty flag for the parameter Mag1 (':') or, if set to 'B', 'b', 'p', 'g', 'V', 'R', 'i', 'I', or 'K' as an indicator that Mag1 is the apparent magnitude in the quoted band, rather than the apparent V magnitude.

Lim_Mag2
A limit flag ('>' or '<') for the magnitude parameter Mag2.

Mag2
The apparent V (or B, if so specified) magnitude at minimum brightness or, in the case of eclipses, the magnitude at mid-eclipse.

Mag2_Flag
This, if set to 'B', 'g', 'R', 'i', or 'I', is an indicator that Mag2 is the apparent magnitude in the quoted band, rather than the apparent V magnitude, or, if set to ':', indicates that the value of Mag2 is uncertain.

Orbital_Period
The orbital period, in days.

Orbital_Period_Flag
This is an uncertainty flag for the orbital period.

Spin_Period
The spin period, in seconds, of the accretor (white dwarf or neutron star).

Eclipse
A flag indicating the occurrence of eclipses as follows: 

            =  : (blank) no eclipses observed.
            =1 : 1 eclipse per orbital revolution observed.
            =2 : 2 eclipses per orbital revolution observed.
            =D : periodic eclipse-like dips observed.
This flag may be appended by '?' to indicate uncertainty.

SB
A flag specifying the type of spectroscopic binary as follows: 

           SB=1: single-line spectroscopic binary
           SB=2: double-line spectroscopic binary

Spect_Type_2
The spectral type of the secondary given in the format of [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.

Spect_Type_1
The spectral type of the primary given in the format of [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.
