Abstract:
Updated data of the 153 Galactic globular clusters are used to
readdress fundamental parameters of the Milky Way, such as the
distance of the Sun to the Galactic centre, the bulge and halo
structural parameters, and cluster destruction rates.
We build a reduced sample that has been decontaminated of all the
clusters younger than 10Gyrs and of those with retrograde orbits
and/or evidence of relation to dwarf galaxies. The reduced sample
contains 116 globular clusters that are tested for whether they were
formed in the primordial collapse.
Description:
Parameters of the 153 presently known globular clusters in the Galaxy
are listed in Table 1.
