CS around Orion-KL : a large rotating disk.
Abstract
J = 1-0 emission of CS and C34S around Orion-KL has been mapped with an angular resolution of 33arcsec. The region of large CS integrated intensity has a single maximum near the KL nebula and is elongated NE-SW. The peak velocity shows a systematic shift along the axis of the elongated feature. This is consistent with an existence of a large rotating disk around the KL nebula. The disk is 4×104AU (0.2 pc) in diameter and is rotating with a period of 5×105yr×sin i, where i is the inclination.
