RITTERRBIN: Help

RITTERRBIN - Ritter Binaries Related to CVs Catalog (7th Edition, Rev. 7.10)


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 7.10, July 2008) of Ritter & Kolb. The latter catalog lists coordinates, apparent magnitudes, orbital parameters, stellar parameters of the components, and other characteristic properties of 731 cataclysmic binaries, 90 low-mass X-ray binaries, and 190 related objects with known or suspected orbital periods. The HEASARC has for simplicity split this catalog into 3 database tables: a table (RITTERLMXB) containing the low-mass X-ray binaries' data, a second one (RITTERCV) containing cataclysmic binaries' data, and the present one (RITTERRBIN) containing the related binaries' data. The literature published before 30 June 2008 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 August 2008 based on the pcbdata.dat file from 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 characterised using the following abbreviations:

            CP = coherent pulsator, contains a coherently pulsating white
                 dwarf or subdwarf
            DD = system consisting of two degenerate components
            DS = detached system
            EC = contains a pulsating sdB star of the EC 14026-2647 type
            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 planetary nebula
            RS = system shows RS CVn-like chromospheric activity
  

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

Type2
The object type as coarsely characterised 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 characterised 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 characterised 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 is set to 'B', 'b', 'p', 'g' or 'K' as an indicator that Mag1 is the apparent B, b, p, g or K magnitude, respectively, 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', is an indicator that mag2 is the apparent B magnitude 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.
