Abstract:
We present an up-to-date catalog of intrinsic iron abundance spreads
in the 55 Milky Way globular clusters (GCs) for which sufficiently
precise spectroscopic measurements are available. Our method combines
multiple data sets when possible to improve the statistics, taking
into account the fact that different methods and instruments can lead
to systematically offset metallicities. Only high spectral resolution
(R>14000) studies that measure the equivalent widths of individual
iron lines are found to have uncertainties on the metallicities of the
individual stars that can be calibrated sufficiently well for the
intrinsic dispersion to be separated cleanly from a random measurement
error. The median intrinsic iron spread is found to be 0.045dex, which
is small but unambiguously measured to be nonzero in most cases. There
is large variation between clusters, but more luminous GCs, above
105L☉, have increasingly large iron spreads on average; no
trend between the iron spread and metallicity is found.
