Joseph A'HEARN

Welcome to my site! I’m an astrophysicist and planetary scientist especially interested in solar system dynamics.  

Download CV

I’m currently a Physics Ph.D. candidate at the University of Idaho.

I’ve been doing research on the dynamics of Saturn’s moons and rings. 

Science

My first scientific paper dealt with energy conservation in co-rotation resonances, with a focus on Saturn’s Aegaeon ring arc.

More recently I’ve been studying co-orbital satellite systems. I won an award for this research in 2019. My second scientific paper makes applications of my findings to phenomena in Saturn’s innermost ringlet.  

ONLINE TEACHING

I have been teaching high school physics for Memoria Press Online Academy since Fall 2018. I plan to teach Advanced Physics in 2021-22. 

I taught a 16-week high school Astronomy course for Kepler Education in Fall 2020. I plan to teach this again in Fall 2021.  

I’m offering a crash course in Astronomy to anyone who is up for it. You will be given access to my 16 video lectures (about 6 hours of content) and you will be invited to engage in discussion during 7 live video chat sessions. Email me if you wish to guarantee that I save you a spot!   

BACKGROUND

I did my undergraduate studies in Physics, with a technical option in Astrophysics, and a second major in Philosophy, at the University of Illinois at Urbana-Champaign. 

I’m also Catholic. Before transferring to UIUC, I spent eleven years, starting with high school, in a formation program to become a Catholic missionary priest. Even though I decided in the end that taking another career path made more sense for me, my adventures and experiences during those years, which I spent in the northeastern United States, Mexico, and Italy, have in large part made me who I am today. I wouldn’t trade my unique path in life for any other.
