Descripción
Introduction: The European Galactic Plane Surveys (EGAPS) will for the
first time ever map the complete galactic plane (10x360 degrees) down to
21st magnitude in u', g', r', i' and H-alpha and partly in He I 5875. It
will complete a database of ~1 billion objects. The aim of EGAPS is to
study populations of short-lived stellar and binary phases in our Galaxy
and combine these population studies with stellar and binary
evolutionary codes to vastly improve our understanding of crucial phases
of stellar evolution. Target populations include Wolf-Rayet stars,
planetary nebulae, white dwarfs (in binaries), cataclysmic variables and
other mass-transferring binaries. Methods: EGAPS is using the INT+WFC on
La Palma for the Northern Hemisphere and will use the VST+Omegacam in
the Southern Hemisphere. Results: The Northern red survey (IPHAS, using
r', i', and Halpha) has started in 2003 and is currently 70% complete.
The northern blue survey (UVEX; u',g',r' and HeI) has started in June
2006. Results include the detection of a number of rare planetary
nebulae, cataclysmic variables, red-dwarf white dwarf binaries in
clusters, a possible AM CVn candidate, and a deep photometric and
spectroscopic investigation of the Cyg X region. Discussion: EGAPS will
revolutionize the field of galactic stellar astrophysics by completing
the first ever digital, multicolour survey of the Galactic Plane.
