Revisiting Variable Stars Near Globular Clusters South of −29° Declination

Revisiting Variable Stars Near Globular Clusters South of −29° Declination

We review an often-cited but seldom-accessed catalogue by Fourcade and Laborde (1966) of 785 variable stars near 47 southern Galactic globular clusters, and recover the locations of 85 stars that were not incorporated into subsequent variable star catalogues and hence have become “lost” to the literature. We match the positions of these stars with those of modern variable star databases (Gaia, ASAS-SN, and VSX) and find 96% appear in at least one of these catalogues. We used proper motions and radial velocities from the Gaia Third Data Release to assess cluster membership, finding that most are field stars, but up to five may be members of NGC 5927 and one of NGC 6624.

期刊介绍: Astronomische Nachrichten, founded in 1821 by H. C. Schumacher, is the oldest astronomical journal worldwide still being published. Famous astronomical discoveries and important papers on astronomy and astrophysics published in more than 300 volumes of the journal give an outstanding representation of the progress of astronomical research over the last 180 years. Today, Astronomical Notes/ Astronomische Nachrichten publishes articles in the field of observational and theoretical astrophysics and related topics in solar-system and solar physics. Additional, papers on astronomical instrumentation ground-based and space-based as well as papers about numerical astrophysical techniques and supercomputer modelling are covered. Papers can be completed by short video sequences in the electronic version. Astronomical Notes/ Astronomische Nachrichten also publishes special issues of meeting proceedings.
