Seeking echoes of circumstellar disks in Kepler light curves. (2021)

Keywords : Circumstellar disks; Debris disks; Exozodiacal dust; Stellar flares Exoplanet astronomy

Abstract:Light echoes of flares on active stars offer the opportunity for direct detection of circumstellar dust. We revisit the problem of identifying faint echoes in postflare light curves, focusing on debris disks from ongoing planet formation. Starting with simulations, we develop an algorithm for estimating the radial extent and total mass from disk echo profiles. We apply this algorithm to light curves from over 2100 stars observed by NASA's Kepler mission, selected for multiple short-lived flares in either the long-cadence or short-cadence data sets. While flux uncertainties in light curves from individual stars preclude useful mass limits on circumstellar disks, catalog-averaged light curves yield constraints on disk mass that are ...(more)

The exquisite photometric time series of the starlight from stars observed by NASA's Kepler satellite (Borucki+, 2010Sci...327..977B) offers a unique opportunity to search for flare echoes. Here we mine the data from stars in the Kepler Input Catalog (KIC) for impulsive flares, seeking the signatures of echoes in composite light curves.
