Stellar X-Ray Variability and Planetary Evolution in the DS Tucanae System

Stellar X-Ray Variability and Planetary Evolution in the DS Tucanae System

We present an analysis of four Chandra observations of the 45 Myr old DS Tuc binary system. We observed X-ray variability of both stars on timescales from hours to months, including two strong X-ray flares from star A. The implied flaring rates are in agreement with past observations made with XMM-N...
