Scientific paper

Using the VLBI observation of this SiO maser, MERLIN observation of the H2O and OH maser, and the emission line of CO(2-1), we have studied the complex space structure of VX Sgr circumstellar envelope, and found that the molecules of SiO, H2O, and OH maser are distributed on multiply separated spheric shells, as are the molecules of CO(2-1). We have also studied the velocity structure and obtained the distribution curve of its field of expanding velocity.
