[3.01] The Search for Extrasolar Trojan Planets: An Update

We are exploring the light curves of eclipsing binaries for the photometric signature of planets that may exist at the L4 and L5 Lagrange points of the stellar system. We have coined such objects ``Trojan planets." The target list includes QY Aql, YZ Aql, V442 Cas, SS Cet, S Cnc, VW Cyg, WW Cyg, RR Dra, RX Gem, RY Gem, VW Hya, Y Leo, TV Mon, BN Sct, UW Vir, AC UMa, and GSC 1657.

We have concentrated on V442 Cas and YZ Aql, based on initial results that show anomalies in the light curves near phases 0.2 and 0.8, respectively. Unusual variations have also been noted in WW Cyg. An up-to-date progress report on the work on all systems will be presented.

We gratefully acknowledge the support of the National Science Foundation, through grants AST-9731062 and AST-0089248. We also appreciate the support of the Fund for Astrophysical Research. Gregory Shelton and Brenda Corbin, at the U.S. naval Observatory Library, have been indispensable in providing references for these binary systems. This research has made use of the Simbad database, operated at CDS, Strasbourg, France
