Abstract:
RR Lyrae stars are of great importance for investigations of Galactic
structure. However, a complete compendium of all RR-Lyraes in the
solar neighbourhood with accurate classifications and coordinates does
not exist to this day. Here we present a catalogue of 561 local
RR-Lyrae stars (Vmax≥12.5mag) according to the magnitudes given in
the Combined General Catalogue of Variable Stars (GCVS) and 16 fainter
ones. The Tycho2 catalogue contains ∼100 RR Lyr stars. However, many
objects have inaccurate coordinates in the GCVS, the primary source of
variable star information, so that a reliable cross-identification is
difficult. We identified RR Lyrae from both catalogues based on an
intensive literature search. In dubious cases we carried out
photometry of fields to identify the variable. Mennessier & Colome
(2002, Cat. J/A+A/390/173) have published a paper with Tyc2-GCVS
identifications, but we found that many of their identifications are
wrong.
