Astronomy on Tap: The Cosmic Neighborhood Watch

Astronomy on Tap Leiden

Astronomy on Tap features scientists and educators who speak of their passion for astronomy and research in an informal setting.

Galerie Cafe Leidse Lente

We are very excited for our next event, which will take place on Monday, June 22nd at Culture Café Leidse Lente at 20:00 CET! This month, we will be focusing on hidden worlds, from distant planets across the galaxy to the dim objects in our immediate cosmic backyard. Jo Ann Egger will talk about how astronomers detect these cloaked exoplanets by watching stars wobble and flicker, while Sam de Regt will take us to the edge of the solar system to explain how we analyze the atmospheres of nearby brown dwarfs. As always, there will be fun games with which you can test your knowledge and try to win cool science prizes! • Jo Ann Egger: “Hunting for planets hiding around other stars” Jo Ann Egger is a research fellow at the European Space Agency, where uses space- and ground-based telescopes to detect and characterise hidden exoplanets between Earth and Neptune in size, aiming to understand what we can learn about their interiors. Jo Ann's talk will focus on how we detect these hidden planets by watching stars wobble and flicker, and what these faint signals reveal about the surprising diversity of worlds across the galaxy. • Sam de Regt: "Meet the Neighbours: Tracing the Origin of the Nearest Brown Dwarfs" Sam de Regt is a final year PhD student at Leiden Observatory, where he leverages different techniques to study the atmosphere of various types of stars including Brown dwarfs. Brown dwarfs are objects that bridge the gap between stars and giant planets. They are much heavier than Jupiter, but not massive enough to brightly shine like stars. Sam's talk will show us how observations with one of the world's largest telescopes allow us to analyse the composition of their atmospheres and uncover tiny chemical patterns in the emitted light. Those fingerprints turn out to hold surprising clues about where and when these neighbouring worlds formed. Logistical information: We start at 20:00 sharp, so please arrive earlier to enter the venue, save a seat, and grab a drink at the bar. We will be uploading a recording of the talks on our <a href="https://www.youtube.com/c/AstronomyonTapLeiden/videos" title="https://www.youtube.com/c/AstronomyonTapLeiden/videos" target="_blank" data-msys-clicktrack="0" rel="nofollow noopener noreferrer">YouTube channel</a> after the event. Join us for an evening of astronomy and fun games where you can win cool science prizes! All ages and backgrounds are welcome!
