Stroemgren photometry of Omega Cen and NGC 6397
Listed in IVOA Registry (Virtual Observatory)
We have observed (with vby filters) a field north of the core of the most massive globular cluster in our galaxy, {omega} Centauri.
Description
We have found a correlation of age and metallicity in a region that avoids the dense core and the inhomogeneous foreground dust emission shown by IRAS. Our observations show that the comparatively metal-rich stars (as defined by the b-y and m_1_ colors) are younger than the metal-poor stars by at least 3 Gyr.
