▁to ▁have ▁inf ra red ▁excess ▁consistent ▁with ▁circum stell ar ▁dis ks ▁or ▁en velop es . ▁ ▁The ▁cluster ▁has ▁been ▁noted ▁by ▁B aba ▁et ▁al . ▁for ▁having ▁a ▁high ▁density ▁of ▁stars , ▁with ▁star ▁counts ▁( the ▁number ▁of ▁stars ▁within ▁an ▁angular ▁area ▁of ▁the ▁sky ) ▁exceed ing ▁ 3 0 0 0 ▁stars ▁per ▁square ▁par sec ▁at ▁the ▁center ▁of ▁the ▁cluster . ▁A ▁measurement ▁of ▁central ▁area ▁density ▁using ▁the ▁MY St IX ▁catalog ▁suggested ▁approximately ▁ 1 0 , 0 0 0 ▁stars ▁per ▁square ▁par sec ▁at ▁the ▁cluster ▁center , ▁but ▁this ▁study ▁also ▁suggested ▁that ▁such ▁dens ities ▁are ▁not ▁unusual ▁for ▁massive ▁star - form ing ▁regions . ▁The ▁spatial ▁distribution ▁of ▁stars ▁has ▁been ▁described ▁as ▁a ▁King ▁profile ▁or ▁altern atively ▁as ▁a ▁" core - hal o " ▁structure . ▁ ▁St ell ar ▁density ▁near ▁the ▁center ▁of ▁RC W ▁ 3 6 ▁has ▁been ▁estimated ▁to ▁be ▁approximately ▁ 3 0 0 , 0 0 0 ▁stars ▁per ▁cub ic ▁par sec ▁( or ▁ 1 0 , 0 0 0 ▁stars ▁per ▁cub ic ▁light ▁year ). ▁In ▁contrast , ▁the ▁density ▁of ▁stars ▁in ▁the ▁Sol ar ▁neighborhood ▁is ▁only ▁ 0 . 1 4 ▁star ▁per ▁cub ic ▁par sec , ▁so ▁the ▁density ▁of ▁stars ▁at ▁the ▁center ▁of ▁RC W ▁ 3 6 ▁is ▁about ▁ 2 ▁million ▁times ▁greater . ▁It ▁has ▁been ▁calculated ▁that ▁for
