Many thanks to the KU Leuven Institute of Astronomy for hosting me to give a seminar about my research! I was lucky enough to also give this talk at the Institute for Environmental Physics at University of Heidelberg and the Institute for Planetary Research at the German Aerospace Center. Great feedback from many diverse perspectivesContinue reading “Can we see atmospheric waves on exoplanets?”

Stratospheric wind and water vapour fluctuations on tidally locked exoplanets
Wind currents in the Earth’s equatorial stratosphere change direction every 26-28 months. Abundances of ozone, methane, water vapour, and other trace atmospheric gasses oscillate on the same timescale. This phenomenon is known as the “quasi-biennial oscillation” (QBO) and also occurs on other solar system planets (Jupiter and Saturn), though with different periods. It occurs becauseContinue reading “Stratospheric wind and water vapour fluctuations on tidally locked exoplanets”
Turn off the stars: Image processing and astronomy
Picture a two-dimensional grid, like a chessboard or a piece of graph paper. Each square on the grid contains a tower of blocks. These towers come in different heights, ranging from zero to 255. “Towers” with zero blocks are black, towers with 255 blocks are white, and every number in between is a shade ofContinue reading “Turn off the stars: Image processing and astronomy”
