摘要：

Diffraction-limited infrared images of the protostellar system Mon R2 IRS 3 reveal a bright conical nebula which extends about 0.5'' south from the southern component of the previously known star pair. The bright nebula is probably dust scattering the starlight which emerges along the polar axis of a large ( greater than or similar to 500 AU) circumstellar disk. We estimate a lower limit to the disk mass of 3 X 10(-2) M.. A faint, previously unknown pointlike source lies 0.37'' east of the northern star.
