Overview

High-cadence analysis reveals intricate flare structures in late-K and M stars, suggesting new insights on exoplanet impacts.

Key Points

  • The aim is to investigate the intricate detailed morphology of white-light stellar flares and their implications for exoplanets.
  • Utilized high-cadence CHEOPS and TESS space telescopes data.
  • Employed specialized software for CHEOPS data reduction.
  • Developed an algorithm to analyze multi-peak flare profiles.
  • Estimated amplitudes and periodicities in quasi-periodic pulsation candidates.
  • Complex flares constitute over 30% of detected events.
  • High-impulse flares occur more frequently than previously estimated.
  • Differences found in duration distributions of flare components; no differences in peak luminosity.
  • Statistical analysis suggests log-normal distribution for flare parameters.
