RITTERRBIN - Ritter Binaries Related to CVs Catalog (7th Edition, Rev. 7.21)

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, Release 7.21, March 2014) of Ritter & Kolb. The complete catalog lists coordinates, apparent magnitudes, orbital parameters, stellar parameters of the components, and other characteristic properties of 1166 cataclysmic binaries, 105 low-mass X-ray binaries, and 500 related objects with known or suspected orbital periods. The HEASARC has for simplicity split this catalog into three 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 January 2014 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.

This table was last updated by the HEASARC in April 2014 based 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:

       BD = secondary star is a brown dwarf
       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
       ZZ = white dwarf shows ZZ Ceti-type pulsations
  

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', '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.
