About


Hi! My name is Amalie and I am a postdoctoral researcher in astrophysics. My primary scientific interest is Galactic archaeology where we learn about the history and evolution of our own galaxy - the Milky Way - by studying the demographics of its stars.

I am current part of the Asterochronometry group at Università di Bologna in Bologna, Italy. I am working on multiple process where we combine the orbits and chemical compositions of stars with ages derived from the study of stellar pulsations known as asteroseismology. The interplay between these observations allows us to make detailed studies of the Milky Way.

I did my PhD at the iSIMBA group at the Stellar Astrophysics Centre at Aarhus University, Denmark. I am also part of the developement team of BAyesian STellar Algorithm (BASTA), which is a flexible pipeline for the inference of stellar properties, such as the masses, radii, and ages of stars.

When I am not studying stars, I enjoy running, playing chess, geeking out over musicals, and puzzling with minor coding projects. Currently, I am working on the litterature puzzle known as Cain's Jawbone, which is taking up most of my spare time. If you are also struggling with the references to Kipling, Wilde, and Sherlock Holmes, and the many Henrys, feel free to write me.

The subgiant HR 7322 as an asteroseismic benchmark star

HR 7322 is a bright star that is slightly more evolved than our Sun in the phase of its evolution known as the subgiant phase. This is from an evolutionary point of view a rather quick phase, lasting only a small fraction of its life as a hydrogen-fusion main-sequence star but during which fundamental structural changes occur in the star.

Bright subgiant stars are interesting as they can be studied using different methods. This makes it possible to test predictions from methods that depend more strongly on our current theory of stellar models against less model-dependent methods.

In this study, we compare the stellar radius from interferometry, which is more-or-less a geometric method of deriving the radius and thus depend very little on the stellar models, to stellar radii estimates from the scaling relations and estimates from detailed stellar modelling, which by nature has a high model-dependence.
