An Interferometric Search for Bright Companions to 51 Pegasi

We report on a near-infrared, long-baseline interferometric search for luminous companions to the star 51 Pegasi conducted with the Palomar Testbed Interferometer. Our data is completely consistent with a single-star hypothesis.

Infrared images of Monoceros R2 IRS 3 - Evidence for a circumstellar disk

Diffraction-limited IR images of the protostellar system Mon R2 IRS 3 reveal a bright conical nebula which extends about 0.5 arcsec 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 500 AU) circumstellar disk. We estimate a lower limit to the disk mass of 3 X 10 exp -2 solar masses. A faint, previously unknown pointlike source lies 0.37 arcsec east of the northern star.
