Resonant structures in exozodiacal clouds created by exo-Earths in the habitable zone of late-type stars
Seung-Yoo Lee, Masateru Ishiguro, Hangbin Jo +1
Earth-like exoplanets can create resonant structures in exozodiacal dust through mean motion resonances (MMRs). These structures not only suggest the presence of such planets, but…
