AbstractResults of high-resolution interferometric observations of CS (2-1) emission from the young stellar object IRAS 00338+6312 and its neighboring region in L1287 are presented. Strong and localized emission has been detected. The global CS distribution appears elongated and has a size of 0.14 pc x 0.08 pc. The CS emission shows drastically different structures at different radial velocities, including a high-velocity bipolar pattern extended over 16 km s(-1) and a flattened structure perpendicular to the outflow axis at lower velocities. The high-velocity lobes are clumpy and have been apparently accelerated. It is found that the IRAS source is located in the central part of the low-velocity CS structure, while three other optical features, including the two FU Orionis candidates RNO 1B and RNO 1C, are located gear or outside the edge of the low-velocity CS component. The possible driving source of the outflow in L1287 is discussed on the basis of the available data.
