High-Precision Spectroscopy for Stellar Magnetic Activity and Exoplanet Detection—Physics and Astronomy Talk

Wednesday, Oct. 27, 2021

3:30 p.m. - 4:30 p.m.

Olin-Rice Science Center 150

Assistant Professor Ryan C. Terrien, Carleton College is presenting: "We now know that exoplanets are common around nearby stars, but the tiny signatures of Earth-like exoplanets remain exceedingly difficult to detect. This is largely due to the magnetic activity on the host stars themselves, which can mask low-level exoplanetary signals. I will discuss our new efforts to leverage the stability and high spectral resolution of new astronomical spectrographs to better measure stellar magnetic activity. These new spectroscopic techniques will help improve the precision and reliability of exoplanet detection, and can also help improve our understanding of magnetic activity in general."
