An intermediate-band photometric study of the "globular cluster" NGC 2419
(2013) 2012 Reading the Book of Globular Clusters with the Lens of Stellar Evolution p.67-70- Abstract
NGC 2419 is one of the remotest star clusters in the Milky Way halo and its exact nature is yet unclear. While it has traits reminiscent of a globular cluster, its large radius and suggestions of an abundance spread have fueled the discussion about its origin in an extragalactic environment, possibly the remnant of the accretion of a dwarf galaxy. Here, we present first results from deep intermediate-band photometry of NGC 2419, which enables us to search for chemical (light element) abundance variations, metallicity spreads, and thus multiple stellar populations through well calibrated Strömgren indices.
