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. [6] It does host a very small debris disk, likely due to disk truncation by the nearby stellar companion. [11] The disk is inclined 38±9° to the plane of sky. It appears to be highly evolved and asymmetric, [12] with indications of flattening and grains growth. [9]
The companion HD 150193B, is a T Tauri young star [5] with a projected separation of 166 AU. [9]
The binary HD 150193 is part of the Upper Scorpius subgroup of Scorpius–Centaurus star-forming region.[ citation needed]
