Orion BN-KL 区域的 H2、CO 和 OH IR 发射线强度是通过以 36 km/s 行进的冲击波模拟的，环境气体密度为 200,000 每立方厘米，电离分数小于 3 x 10 的 -7 次方，CO 丰度约为 0.0003，横向磁场为 0.45 毫高斯。考虑了一个全球模型，其中冲击波是由来自吉隆坡的强风驱动的。大约 1000 年来，质量损失率每年不低于 0.003 个太阳质量。恒星释放的总风能不少于 5 x 10 至 47 尔格。总喷射动量约为 10 至 41 g cm/S，足以破坏 BN-KL 周围的稠密云。
The H2, CO, and OH IR emission-line intensities in the BN-KL region of Orion are modeled by shock waves traveling at 36 km/s with respect to an ambient gas of density 200,000 per cu cm, ionization fraction of less than 3 x 10 to the -7th, CO abundance of approximately 0.0003, and transverse magnetic field of 0.45 milligauss. A global model is considered in which the shock waves are driven by strong winds emanating from KL. The mass-loss rate has been not less than 0.003 solar mass per year for approximately 1000 years. The total wind energy released from the star is not less than 5 x 10 to the 47th ergs. The total ejected momentum is approximately 10 to the 41st g cm/S, sufficient to disrupt the dense cloud surrounding BN-KL.
