Ritter Low-Mass X-Ray Binaries Catalog (7.21 Edition)

This HEASARC database table contains information on low-mass X-ray binaries (LMXBs) 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 (RITTERLMXB) containing the low-mass X-ray binaries' data, a second one (<a href="/W3Browse/star-catalog/rittercv.html">RITTERCV</a>) containing cataclysmic binaries' data, and a third one (<a href="/W3Browse/star-catalog/rittercv.html">RITTERRBIN</a>) containing the related binaries' data. The literature published before 1 January 2014 has, as far as possible, been taken into account. 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. This table was last updated by the HEASARC in April 2014 based on the lmxbdata.dat file from the <a href="https://cdsarc.cds.unistra.fr/ftp/cats/B/cb">CDS Catalog B/cb</a>. This is a service provided by NASA HEASARC .
