I am post-doctoral researcher in astrophysics at Leiden Observatory. I am interested in stellar rotation, observable signatures of coronal mass ejection modelling, and the role of space weather in determining the habitability of extrasolar planets. To study these phenomena I often use high-performance computers and three-dimensional numerical codes such as the Space Weather Modelling Framework developed at the University of Michigan.
At Leiden Observatory I have enjoyed supervising M.Sc. and Ph.D. students in the astronomy program; please contact me if you are interested using numerical modelling to study star-planet interactions in 2024/2025!
In my Ph.D. project at the University of Southern Queensland we produced the largest atlas of three-dimensional wind maps of young, Sun-like stars to date. The wind maps were based on magnetic maps of the stellar photosphere, obtained by Folsom et al. (2016, 2018) with Zeeman-Doppler Imaging (ZDI). We then used three-dimensional numerical (SWMF/BATSRUS) simulations to produce stellar wind maps covering the stellar corona and astrosphere. The project combined solar physics, space physics, astronomy, and numerical simulations and the results were published in a series of papers (Evensberget et al. 2021, 2022, 2023).
Recorded talks
During Covid many conference talks were recorded as well as presented on-line to a live audience. Here are three contributed talks I gave in 2021 presenting some of the results of my Ph.D. research:
“Inferring the history of the Solar wind from stellar magnetic field observations” at the ASTRO3D ECR Austronomers in Australia Seminar (26 minutes).
“Can we infer the history of the Solar wind from stellar magnetic field observations?” at the Astronomical Society of Australia Annual Science Meeting (10 minutes).
“Probing the effect of magnetic geometry and field strength on stellar spin-down with MHD simulations” at the 9th BCool meeting (5 minutes).
