# Conny Aerts

Conny Clara Aerts, born 26 January 1966, is a Belgian (Flemish) professor in astrophysics. She specialises in asteroseismology. She is associated with KU Leuven and Radboud University, where she leads the Chair in the Astroseismology group. In 2012, she became the first woman to be awarded the Francqui Prize in the category of Science & Technology. In 2022, she became the third woman to be awarded the Kavli Prize in Astrophysics for her work in asteroseismology.

## Biography

Aerts was born in Brasschaat, Belgium. She received her Bachelor and Master in Mathematics from the University of Antwerp. She participated in the International Astronomical Youth Camp in 1987 and 1988. She then went on to complete her PhD in 1993 at KU Leuven. After completing she spent several months doing research at the University of Delaware. She was a postdoctoral fellow with the Fund for Scientific Research from 1993 to 2001, when she was appointed lecturer at KU Leuven. She became first associate professor in 2004, and then full professor in 2007 at KU Leuven.

## Research

In her research, she uses the star oscillations to determine the internal rotation profile of stars. The oscillations are obtained from both ground and space-based telescopes. In her PROSPERITY project, she used data obtained from the CoRoT satellite and the NASA Kepler satellite. She is currently the Belgian principal investigator on the PLATO mission.
Aerts developed methodology using Gaussian mixture classification to analyse the data. She uses this to determine the star structure and inform stellar models within stellar evolution theory. With these techniques she has made a number of discoveries, including that of non-non-rigid rotation in giant stars.
The theoretical models she develops based on the star oscillations also allow her determine the age of stars with a high accuracy.
Aerts has twice been awarded an Advanced Grant by the European Research Council (ERC): in 2008 for PROSPERITY, and again in 2015 for a project entitled MAMSIE (Mixing and Angular Momentum Transport of Massive Stars).

## Outreach

Aerts is Vice-Dean of Communication & Outreach at the Faculty of Science at KU Leuven. She is outspoken about the need to increase gender equality in the sciences, and is a member of the International Astronomical Union Women in Astronomy Working Group.
