The Curious Case of Cold Giant Planets
December 6th, 2018 – 8:00 PM
Speaker: Miranda Herman
Location: Room 103, McLennan Physical Laboratories (60 St. George Street)
Planetarium tickets will be handed out at 7:45 PM outside of the lecture room on a first-come first-served basis. Any remaining planetarium tickets will be available after the talk.
Cold gas giant planets with long orbital periods make up half of the planets in our Solar System, yet we have observed only a handful of similar exoplanets around other stars. Is this due to the limitations set by our observation methods, or are cold giants truly rare in nature? In this talk I will explore the difficulties associated with finding such exoplanets, describe my efforts to increase the number of known cold giants, and discuss how they can inform us about the population of exoplanets as a whole.
About the Speaker
Miranda Herman is a 3rd-year PhD student in the Department of Astronomy & Astrophysics at UofT. Her research focuses on the characterization of exoplanets and planetary systems, from elusive cool gas giants to the hottest planets ever discovered. Outside of astronomy she enjoys playing board games, reading, and planning trips to much warmer destinations.
The U of T Astronomy Public Tour, or AstroTour, is a monthly event operated by the graduate students of the U of T Astronomy Department. The Tour features a public lecture by a member of the Department on topics ranging from their research to great moments in astronomical history. Following the lecture, tour-goers can peer at the night sky through the Department’s balcony and dome telescopes, or watch a planetarium show run live by astronomer. Admission to the tour is free. Seating for the lecture is on a first-come, first-served basis (doors open ten minutes before the start of the lecture), and the telescope observing is walk-in. The planetarium shows require tickets, which will be available at the event on a first-come first-served basis.
The AstroTours are generously financed by the Department of Astronomy and Astrophysics and the Dunlap Institute for Astronomy and Astrophysics.
