Akke Corporaal
Postdoctoral research Fellow at ESO Chile

About me

I’m Akke Corporaal, an astronomer holding an ESO Fellowship position in Chile since May 2024. I split my time between my own astrophysical research and supporting telescope operations at Paranal Observatory, in the Atacama desert in Chile. For my scientific work, I’m interested in discs around Sun-like stars across stellar evolution and the study of planet formation processes. I focus on the observational side using some of the most powerful ground based infrared facilities, mainly the interferometric instruments that are installed on the Very Large Telescope Interferometer (VLTI) at Paranal. I’m using these high angular resolution observations to uncover the tiniest details to understand the ongoing physical processes in circumstellar discs. For the operational part of the fellowship, I am a support astronomer at the VLTI and the deputy instrument scientist for VLTI/MATISSE: a perfect synergy between science and operations.
My scientific interests lie in intersection of the fields of evolved stars and circumstellar disc physics. In particular, I study circumstellar discs that are found around a class of evolved binary stars, namely post-asymptotic giant branch binary systems. I aim to unravel their properties and compare them to protoplanetary discs around young stars, which are known environment for ongoing planet formation processes. To understand the structure of the discs around these evolved binary systems as well as how they evolve, I’m using infrared interferometric techniques to reveal the inner regions of the disc. With (a combination of) datasets of the PIONIER, GRAVITY, and MATISSE instruments on the VLTI, I study these disc regions in unprecedented detail. As such, I’m using models and reconstructed images to not only understand the physical processes in these discs, but also how they might relate to planet formation processes, and how the interaction between the disc and the stars influence the further evolution of the system. Some of my recent work is highlighted here.
Besides doing and communicating research, I have been involved in organisational, educational, and outreach activities.
If I’m not doing astronomy, I love to dance, to make (unprofessional personal) lyrical dance choreographies, to go for a walk or hike, to write poems, to bake, to read, and to learn or improve on a new language. I’m also always in to having a nice social gathering both indoors and outdoors.
