Space debris detection in optical image sequences

Applied Optics, 2016
We present a high-accuracy, low false-alarmrate, and low computational-cost methodology for removing stars and noise and detecting space debris with low signal-to-noise ratio (SNR) in optical image sequences. First, time-index filtering and bright star

Space debris and planet detection [PDF]

Astronomy and Geophysics, 2006
Rings of "space debris" are seen around nearby stars, resulting from the collisions of extrasolar comets. These rings are in fact the brightest aspect of another stellar system after the star itself, with the collisionally generated dust emitting ...
