    Nodal precession of WASP-33b for 11 yr by Doppler tomographic and transit photometric observations
    WASP-33b, a hot Jupiter around a hot star, is a rare system in which nodal precession has been discovered. We updated the model for the nodal precession of WASP...

    Non-Vestoid candidate asteroids in the inner main belt
    Context. Most howardite-eucrite-diogenite (HED) meteorites (analogues to V-type asteroids) are thought to originate from the asteroid (4) Vesta. However some...
