The exotic range of known planetary systems has provoked an equally physical explanations for their diverse architectures. However, constraining formation processes requires mapping the observed exoplanet population to that which initially formed in protoplanetary disc. Numerous results suggest (internal or external) dynamical perturbation alters architectures some exoplanetary systems. Isolati...

The High-Energy Lightcurve Generator (HILIGT) is a new web-based1 tool which allows the user to generate long-term lightcurves of X-ray sources. It provides historical data and calculates upper limits from image in real-time. HILIGT utilizes twelve satellites, both modern missions such as XMM-Newton Swift, earlier facilities ROSAT, EXOSAT, Einstein or Ariel V. Together, this enables query 50 ye...
