The stellar halo of the Galaxy
A Helmi - The Astronomy and Astrophysics Review, 2008 - Springer
Stellar halos may hold some of the best preserved fossils of the formation history of galaxies.
They are a natural product of the merging processes that probably take place during the …

Updated parameters of 1743 open clusters based on Gaia DR2
In this study, we follow up our recent paper (Monteiro et al.) and present a homogeneous
sample of fundamental parameters of open clusters in our Galaxy, entirely based on Gaia …
