Daniel Hey

Hey, I’m Dan Hey, an astronomer at the University of Hawaiʻi at Mānoa. I mostly work on asteroseismology, which is the study of stellar pulsations. Similar to how seismology studies vibrations in Earth, asteroseismology studies the vibrations of a star. By analyzing these stellar pulsations we can gain insight into a star’s internal structure, composition, and evolutionary state.

I am particularly interested in the pulsation characteristics of A-type stars (δ Scuti and roAp variables), as well as evolved red giant variables. Recently, I have been working on mapping the kinematics and structure of the Milky Way using long-period variables.

Besides asteroseismology, I do a good amount of programming and a bad amount of statistics. I have a keen interest in Gaussian Processes, and how they can be applied to time-domain astronomical data. Outside of work, I like silversmithing, hiking, and baking bread.

My previous website was a choose your own adventure game which I worked far too hard on. I have archived it here. Enjoy!
