PoW for Oct. 12 :: M3, NGC6752, binaries…

Hello, welcome to another issue of “Papers of the Week”,
covering publications and preprint related to the world of (Galactic) Globular Clusters!

The Gclusters database is under “heavy” developement at the time writing, so the bibliography is NOT updated in the database, but only in this blog,  for the moment. In a short time I should reach a working new configuration (meanwhile…,if you’re experienced with PHP/Mysql and have some spare time.. well, let me know!)

Hello, welcome to another issue of “Papers of the Week”, covering publications and preprint related to the world of (mostly) Galactic Globular Clusters.

Topics of this issue, range from extragalactic systems (NGC 5866) to expected planets in GCs, including also a bit of (extreme!) Horizontal Branches stars… Happy reading ! ;)

PoW for Sept. 28 :: FSR584, abundances, compact objects…

Hello, welcome to another issue of “Papers of the Week”, covering publications and preprint related to the world of Galactic Globular Clusters!

This issue features the entry (as a preprint on astro-ph) of the discover of *another* globular clusters in our Galaxy, FSR584 (see the paper by Bica et al.), as well as a good amount of publications on abundances, variability and compatc objects.

As always, any feedback on PoW will be much appreciated ;)
