A stellar flare can brighten a planet in orbit around its host star, producing a light curve with a faint echo. This echo, and others from subsequent flares, can lead to the planet's discovery, revealing its orbital configuration and physical characteristics. A challenge is that an echo is faint relative to the flare and measurement noise. Here, we use a method, based on autocorrelation function estimation, to extract faint planetary echoes from stellar flare light curves. A key component of… Expand
