The Next Generation Transit Survey (NGTS) is a state-of-the-art wide-field photometric facility comprised of 12 independent robotic telescopes based at ESO’s Paranal Observatory. NGTS is conducting a systematic survey of nearby young open clusters with ages between 1 Myr - 3 Gyr, which are each being monitored at 12-second cadence every clear night over 200-250 day periods. Our aims are to:

  • Characterise the evolution of stellar rotation, active region lifetimes, flares, and the star-disk interaction;
  • Detect and characterise transiting planets and eclipsing binaries.

10 open clusters have been observed to date, with early results providing new insights into the early evolution of stellar rotation, flare frequency and the star-disk interaction, as well as precise constraints on stellar evolution theory from new, well-characterised eclipsing binary systems.
