Large-amplitude Variability Driven By Giant Dust Storms On A Planetary-mass Companion
Large-amplitude variations are commonly observed in the atmospheres of directly imaged exoplanets and brown dwarfs. VHS 1256B, the most variable known planet-mass object, exhibits a near-infrared flux change of nearly […]
