Issue Date: | 2016 | Journal: | MEMORIE DELLA SOCIETA ASTRONOMICA ITALIANA | Number: | 87 | First Page: | 693 | Abstract: | We present the results of a project aimed at characterizing the spectro-photometric properties of the Galactic globular cluster NGC 6362. Our study reveals the presence of two distinct populations, making NGC 6362 the least massive globular (M<SUB>tot</SUB>∼5*10<SUP>4</SUP> M<SUB>☉</SUB>) where both photometric and spectroscopic signatures of multiple populations have been found. Also, we observe that in this system the first and second generation stars share the same radial distribution across the entire cluster extension. At variance with the other Galactic globular clusters (dominated by second generation stars), NGC 6362 is composed of a mixture of the two populations in a similar proportion. | URI: | http://hdl.handle.net/20.500.12386/26302 | URL: | http://sait.oat.ts.astro.it/MSAIt870416/index.html | ISSN: | 0037-8720 | Bibcode ADS: | 2016MmSAI..87..693M | Fulltext: | open |
