Catalogue of Cataclysmic Binaries,
Low-Mass X-Ray Binaries and Related Objects
RKcat Edition 7.12 (1 July 2009)
by Hans Ritter and Ulrich Kolb
Please refer to this catalogue as: Ritter H., Kolb U. 2003, A&A, 404, 301 (update RKcat7.12, 2009)
This catalogue lists coordinates, apparent magnitudes, orbital
parameters, stellar parameters of the components and other
characteristic properties of cataclysmic binaries, low-mass
X-ray binaries and 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 a subset of the objects,
and a cross-reference list of alias object designations.
This is a no-frills catalogue website, focusing on content and
simplicity for both user and data provider.
We publish updated data regularly about every six months; updates will
be announced on the ``What's new?'' page. There will be no detailed
differential list specifying the changes. Instead, we archive the main
data tables (for CVs, LMXBs, related objects) before each
update. Archived tables will be accessible for at least five years.
For the current edition (7.12), literature published before
30 June 2009 has, as far as possible, been taken into account.
This edition has entries for 815 CVs, 91 LMXBs, and 227 related
objects.
