Research

Here are some more specific (randomly ordered) research topics I’m interested in…

Asymptotic giant branch (AGB) stars

• S-type stars and carbon stars
• s-process and the third dredge-up
• Pulsation and mass-loss on the AGB

Stellar variability

• Long period variable (LPV) stars, particularly semiregular and Mira variables
• Long secondary periods of LPVs
• Side interests: Type II Cepheids (especially RV Tauri variables), red supergiant (RSG) variables

Low-mass stellar evolution

• Detailed stellar evolution codes, eg. the Monash stellar evolution code, Modules for Experiments in Stellar Astrophysics (MESA)
• Thermohaline mixing on the red giant branch
• Side interests: Li-rich giants, carbon deficient giants (CDGs)

Astrophysical time-series

• Analysis of variable star light curves
• Gaussian process regression
• Large photometric surveys
