CCD Photometry of the Globular Cluster omega Centauri. II. Stellar Populations and Age-Metallicity Relation
S. -C. Rey, Y. -W. Lee, C. Ree +3
We present wide-field and high-precision BV and Ca & Stromgren by photometry of omega Centauri, which represents one of the most extensive photometric surveys to date for this clus…
Omega Centauri as a Disrupted Dwarf Galaxy: Evidence from Multiple Stellar Populations
Young-Wook Lee, Soo-Chang Rey, Chang H. Ree +4
Our recent CCD photometry (Lee et al. 1999) has shown, for the first time, that omega Cen has several distinct stellar populations, which is reminiscent of the Sagittarius dwarf ga…
Wide-field High-precision CCD Photometry of omega Centauri and Its RR Lyrae Stars
Soo-Chang Rey, Jong-Myung Joo, Young-Jong Sohn +3
We present wide-field and high-precision BV and Ca & Stromgren by photometry of omega Centauri and its RR Lyrae stars, which represents one of the most extensive photometric survey…
CCD Photometry of the Globular Cluster Omega Centauri. I. Metallicity of RR Lyrae Stars from Caby Photometry
Soo-Chang Rey, Young-Wook Lee, Jong-Myung Joo +2
We present new measurements of the metallicity of 131 RR Lyrae stars in the globular cluster Omega Centauri, using the hk index of the Caby photometric system. The hk method has di…
Multiple Stellar Populations in the Globular Cluster omega Centauri as Tracers of a Merger Event
Young-Wook Lee, Jong-Myung Joo, Young-Jong Sohn +3
The discovery of the Sagittarius dwarf galaxy, which is being tidally disrupted by and merging with the Milky Way, supports the view that the halo of the Galaxy has been built up a…
