Identifier: http://hdl.handle.net/1959.14/295988
Description: It is now commonly accepted that globular clusters (GCs) have undergone a complex formation and that they host at least two stellar generations. This is a recent paradigm and is founded on both photom ... More

Identifier: http://hdl.handle.net/1959.14/300529
Description: In the complex picture of multiple stellar populations in globular clusters (GCs), a special role is played by NGC 5139 (ω Centauri). At variance with the majority of GCs, ω Cen exhibits significant s ... More

Identifier: http://hdl.handle.net/1959.14/206515
Description: The Galactic globular cluster NGC 1851 has raised much interest since Hubble Space Telescope photometry revealed that it hosts a double subgiant branch. Here we report on our homogeneous study into th ... More
