Studying planetary habitability using ultraviolet light

Tansu Daylan, an assistant professor of physics in Arts & Sciences at Washington University in St. Louis, was selected by NASA to join the Ultraviolet Transient Astronomy Satellite (ULTRASAT) science team. Daylan, a faculty fellow of the McDonnell Center for the Space Sciences, is one of 14 U.S.-based researchers pursuing science investigations that will contribute to ULTRASAT, Israel’s first space telescope mission, which is expected to launch in 2026.

Daylan’s team will develop a data analysis and modeling pipeline for the ULTRASAT mission to detect and characterize brief increases in stellar brightness, known as stellar flares. Cataloging these flares across different types of stars will enable novel investigations into the magnetic activity of stars and improve the census of space weather beyond our solar system.

Daylan also plans to use ULTRASAT’s deep and wide-field near-UV observations to model atmospheric escape and assess planetary habitability around low-mass stars.
