AN M DWARF COMPANION AND ITS INDUCED SPIRAL ARMS IN THE HD 100453 PROTOPLANETARY DISK

ABSTRACT Recent VLT/SPHERE near-infrared imaging observations revealed two spiral arms with a near m = 2 rotational symmetry in the protoplanetary disk around the ∼1.7 M Herbig star HD 100453. A ∼0.3 M M dwarf companion, HD 100453 B, was also identified at a projected separation of 120 AU from the p...
