In my research, I use knowledge of stars and stellar evolution to understand
unusual stars in dense places, their interactions and their effect on their
A selection of questions that my group is interested in:
- Blue Straggler Stars
- What are the expected pulsation characteristics of collisional & mass transfer blue straggler stars? Are those in agreement with the observations?
- What happens to the angular momentum in a stellar collision
and during the subsequent evolution of the product? Is this the same or different for binary mass transfer products?
- Globular Cluster Formation and Dynamics:
- How can we explain the multiple populations now seen in globular clusters? Are the current explainations viable? What other ingredients are required to fully understand this problem?
- What are the connections between local clustered star formation and the formation & evolution of globular clusters?
I answer these questions using a variety of theoretical techniques and
computer codes. Depending on the situation, I use stellar evolution
codes, smoothed particle hydrodynamic codes or stellar dynamics codes,
running on computers which range from laptops to supercomputers.
I am an active member of collaborations with researchers from Canada, the US
and Europe, including the MODEST
(MOdelling DEnse STellar Systems) collaboration and the MYStIX collaboration.
