HD 150193
HD 150193 is a binary star system in the constellation of Ophiuchus. The primary star was identified as a Herbig Ae/Be star with a strong solar wind, losing approximately a tenth of solar mass per million years.[2] It does host a very small debris disk, likely due to disk truncation by the nearby stellar companion.[8] The disk is inclined 38±9° to the plane of sky. It appears to be highly evolved and asymmetric,[9] with indications of flattening and grains growth.[6]
