Identifier: http://hdl.handle.net/1959.14/1247255
Description: Galactic globular clusters (GCs) are now known to harbour multiple stellar populations, which are chemically distinct in many light element abundances. It is becoming increasingly clear that asymptoti ... More

Identifier: http://hdl.handle.net/1959.14/306635
Description: The velocity dispersions of stars near the Sun are known to increase with stellar age, but age can be difficult to determine, so a proxy like the abundance of α elements (e.g., Mg) with respect to iro ... More
