The Multiplicity of Main Sequence Turnoffs in Globular Clusters
نویسنده
چکیده
We present color-magnitude diagrams of globular clusters for models with self-enrichment and pre-enrichment. The models with self-enrichment turn out to have two or more main sequence turnoff points in the color-magnitude diagram if the fraction of mass lost by the globular cluster under supernova explosions does not exceed 95–97%. The models with pre-enrichment can have only one main sequence turnoff point. We argue that the cluster ω Cen evolved according to a self-enrichment scenario.

Omega Centauri: the Population Puzzle Goes Deeper
We present HST observations that show a bifurcation of colors in the middle main sequence of the globular cluster ω Centauri. We see this in three different fields, observed with different cameras and filters. We also present high precision photometry of a central ACS field which shows a number of main-sequence turnoffs and subgiant branches. The double main sequence, the multiple turnoffs and ...
متن کاملKeck Spectroscopy of Two Young Globular Clusters in the Merger Remnant Ngc 3921
Low-resolution, ultraviolet-to-visual spectra of two candidate globular clusters in the merger remnant NGC 3921 (cz LG = 6021 km s−1) are presented. These two clusters of apparent magnitude V ≈ 22.2 (MV ≈ −12.5) lie at projected distances of about 5 kpc (0.9Reff ) from the center and move with halo-type radial velocities relative to the local galaxy background. Their spectra show strong Balmer ...

Recent, high precision photometry of Omega Centauri, the biggest Galactic globular cluster, has been obtained with Hubble Space Telescope (HST). The color magnitude diagram reveals an unexpected bifurcation of colors in the main sequence (MS). The newly found double MS, the multiple turnoffs and subgiant branches, and other sequences discovered in the past along the red giant branch of this clu...
متن کاملHorizontal - Branch Models and the Second - Parameter Effect . Iv
We present a detailed analysis of the “second-parameter pair” of globular clusters M3 (NGC 5272) and Palomar 3. Our main results can be summarized as follows: i) The horizontal-branch (HB) morphology of M3 is significantly bluer in its inner regions (observed with the Hubble Space Telescope) than in the cluster outskirts (observed from the ground), i.e., M3 has an internal second parameter. Mos...
متن کاملHigh–resolution simulations of stellar collisions between equal-mass main-sequence stars in globular clusters
We performed high–resolution simulations of two stellar collisions relevant for stars in globular clusters. We considered one head-on collision and one off-axis collision between two 0.6 M⊙ main sequence stars. We show that a resolution of about 100 000 particles is sufficient for most studies of the structure and evolution of blue stragglers. We demonstrate conclusively that collision products...
