Reddening, Colour and Metallicity of the M31 Globular Cluster System

Z. Fan, J. Ma, R. de Grijs +2

Using metallicities from the literature, combined with the Revised Bologna Catalogue of photometric data for M31 clusters and cluster candidates (the latter of which is the most co…

New age estimates of M31 globular clusters from multi-colour photometry

Z. Fan, J. Ma, R. de Grijs +2

The large majority of extragalactic star cluster studies performed to date essentially use multi-colour photometry, combined with theoretical stellar synthesis models, to derive ag…

A "super" star cluster grown old: the most massive star cluster in the Local Group

J. Ma, R. de Grijs, Y. Yang +5

We independently redetermine the reddening and age of the globular cluster 037-B327 in M31 by comparing independently obtained multicolour photometry with theoretical stellar popul…
