Uncovering the lives of massive binary stars

Originally from Chile, I moved to Scotland for my PhD to specialise in massive binary stars. After postdoctoral work at KU Leuven, I am now at the Max Planck Institute for Astronomy in Heidelberg, studying how massive stars live, interact, and die.

Massive binaries power some of astrophysics’ most energetic phenomena, yet their demographics remain poorly constrained. I combine large spectroscopic surveys with targeted follow-up programmes, building pipelines to measure stellar properties and describe these systems as populations. With those constraints, I test binary-evolution pathways, identify interaction products, and search for massive stars hiding black-hole companions.

What drives my research

01

How do binary demographics change with environment and metallicity?

02

What do interaction products reveal about mass transfer and mergers?

03

How can we efficiently uncover compact companions at survey scale?
