High-Velocity Exoplanet Systems in May!

Posted on May 19, 2025May 21, 2025 by Jamie

May is here and Friday, May 23 at Jack Fields Elementary School is when and where you want to be! Not only will we have our usual top-notch astronomy presentations, but there will also be Subway sandwiches, chips, water and soft drinks for those in attendance! Please feel free to bring a dessert to share.

At 6:30, Justin McCollum will present Methods of Hopping Across the Night Sky!

At 7:30, Sean Terry will be talking about gravitational microlensing and some the work he has done using this technique.

Presentation overview:

Since the early 2000’s gravitational microlensing has been used to discover and characterize exotic objects in our galaxy, including icy exoplanets, free-floating planets, and isolated black holes. In this presentation, Sean will give an overview of the microlensing technique and his recent work to follow-up one planetary system that appears to have the highest velocity ever measured. This nearly hyper-velocity system (540 km/s) is just below the escape velocity for stars within the galactic center region. He will conclude with a discussion of the implications for high-velocity exoplanet systems, and the promise of the Nancy Grace Roman Space Telescope microlensing mission to discover more systems like this.   – Dr. Sean Terry bio

Good stuff.

 

Come hungry and… see you there!
