I was wondering if someone knows of a source which is after 2004
and which would be more recent (not that I am complaining that 2004 is
outdated but just in case there is something more recent which I could not
locate).

Anthony,

Looking at Salaris's paper in NASA/ADS:

http://adsabs.harvard.edu/cgi-bin/np...?bibcode=2004A

There are 27 articles that cite the Salaris article. Two those in
late 2004 look interesting. I would try the NASA/ADS link and the
"Citations to the Article" link. See if anything looks interesting.

The following also may be of interest. The following is a plot of 186
OC ages from my personal DSO observing list.

The galactic year, the time it takes the Sun to complete one
revolution around the Milky Way's core, is approx. 220 million years
or 8.34 log10(years). Half of all open clusters disperse in just under
one galactic year (8.13 log10(years) or 218 million years) - ripped
apart by tidal forces. The third quartile of open clusters disperses
in just under two galactic years (8.6 log10(years) or about 430
million years).

Popular old clusters and moving groups that have survived more than
two galactic years and into the fourth quartile include M044 (Beehive
Cluster), M048, M067, M073, M093, the Hyades Moving Group, and the
Coma Berenices Star Cluster.

The youngest clusters in my list are aged around 6.7 log10(years) or
approx. 5 million years old. The youngest three are the Tau CMa
Cluster a.k.a. the Northern Jewel Box (NGC2362, Caldwell 64); NGC1980
surrounding iot Orion in the Orion stellar nursery region; and,
NGC2239, a star cluster associated with the Rosetta Nebula stellar
nursery in Mon.

Most of the OC ages were assigned to OC's in my master DSO observing
list are from tables in Allen's Astrophysical Quantities (2000).
