N. van der Marel: "A, B and the Milky Way: What are the Oort constants?"

This event took place at Cultuur Café Leidse Lente in Leiden on February 17, 2025. N. van der Marel: "A, B and the Milky Way: What are the Oort constants?" Nienke van der Marel: “A, B and the Milky Way: what are the Oort constants?” Nienke van der Marel is an assistant professor at Leiden Observatory. In her daily life she studies how planets are forming in dusty disks around young stars, using telescopes like ALMA and, in the future, the ELT. However, she is also fascinated by the history of astronomy, and how the way of thinking about the Universe has changed over the decades with the development of new telescopes and instruments. One of such developments is the story of the Oort constants, which are painted as a mural on a wall on the Witte Singel, across the old Observatory. In this talk she will explain how Jan Oort came up with these equations, his struggles with understanding the Milky Way, and what the A and B actually represent. The other speaker of the night was P. Mancera: "Weighing dark matter in galaxies".
