# Effects of an Embedded B-star Wind on the Properties of the Near-by Cloud: Ophiuchus

Abstract

Abstract. $$\rho$$ Ophiuchii is a group of five B-stars, embedded in a nearby molecular cloud: Ophiuchus, at a distance of $$\sim$$ 119 pc. A “bubble”-like structure is found in dust thermal emission around $$\rho$$ Oph. The circular structure on the H$$\alpha$$ map further indicates that this bubble is phys
