摘要
12COJ=1-0成图观测表明在IRAS19282+1814附近存在着一个蓝向单极高速分子外流.计算了其基本参量并进行了分析.它的成协红外源IRAS19282+1814可能是大质量年轻星体,其IRAS波段色指数表明该源深埋于气体和尘埃物质之中.由60-100μm流量密度获得尘埃温度为30K.它的附近没有其他的源,所以IRAS19282+1814可能是外向流的驱动源.
Mapping with 12CO J=l-0 indicates that there is a high-velocity molecular outflow near the IRAS19282+1814, which is blue monopolar. Parameters of the outflow were calculated. The associated infrared source IRAS19282+1814 may be a massive young stellar object (YSO), which is embedded in the surrounding gas and dust according to the IRAS color indices. There is no other source neaeby, so IRAS19282+1814 probably drives the outflow.
