Rapid rotation reshapes the stellar surface of massive stars, flattening them at the equator. It also creates strong temperature variations across their surfaces, with hotter poles and cooler equatorial regions.

I build 3D-surface models that let us measure these stars as they really are... not as simple spheres.

Hello, I'm Daniel

I'm a PhD candidate at the Instituto de Astrofísica de Canarias, studying massive stars at the limits of rapid rotation. I combine observations, 3D stellar models, and open-source software to understand how rotation reshapes their surfaces, and how we can measure these stars more realistically.
