Simultaneous observations of SU Aur and AB Aur requested for XMM-Newton
Active Dates: Feb. 15, 2012 – Feb. 17, 2012
Abstract:
Dr. Hans Moritz Guenther has requested bracketing and simultaneous observations in support of XMM-Newton x-ray observations of the classical T Tauri star SU Aur and the close-by Herbig Ae star AB Aur scheduled for February 15 - 17, 2012. Your observing assistance is essential for correlation of the x-ray data.
Justification:
The scientific goal of the observation is to study the rise and decay of flares in classical T Tauri stars at a relatively high time resolution (less than minutes). Because T Tauri stars are surrounded by an accretion disk and actively accrete matter from the star, there is reason to believe that flares on T Tauri stars behave differently compared to flares on older stars like our sun.
