Title: | ACS Photometry of the Remote M31 Globular Cluster B514 | Authors: | GALLETI, SILVIA Federici, L. BELLAZZINI, Michele BUZZONI, Alberto Pecci, F. Fusi |
Issue Date: | 2006 | Journal: | THE ASTROPHYSICAL JOURNAL | Number: | 650 | Issue: | 2 | First Page: | L107 | Abstract: | We present deep F606W, F814W ACS photometry of the recently discovered globular cluster B514, the outermost known globular in the M31 galaxy. The cluster appears quite extended, and member stars are unequivocally identified out to ~200 pc from the center. The color-magnitude diagram reveals a steep red giant branch (RGB), and a horizontal branch extending blueward of the instability strip, indicating that B514 is a classical old metal-poor globular cluster. The RGB locus and the position of the RGB bump are both consistent with a metallicity [Fe/H]~-1.8, in excellent agreement with spectroscopic estimates. A preliminary estimate of the integrated absolute V magnitude (M<SUB>V</SUB><~-9.1) suggests that B514 is among the brightest globulars of M31. <P />Based on observations with the NASA/ESA Hubble Space Telescope, obtained at the Space Telescope Science Institute (STScI), which is operated by AURA, Inc., under NASA contract NAS 5-26555. | URI: | http://hdl.handle.net/20.500.12386/34639 | URL: | http://arxiv.org/abs/astro-ph/0609439v1 https://iopscience.iop.org/article/10.1086/508884 |
