Elisha Polomski's
research is revealing the detailed structure of the circumstellar environments
of the Herbig Ae/Be stars. These stars are about 2-10 times the mass of
our sun and associated with large infrared excesses. Many researchers have
fit models to the infrared excesses of these stars which imply that it
originates in dusty circumstellar disks. However, until recently, most
mid-IR observations of these stars consisted of large aperture photometry
and the details of their environments were not known. Elisha's observations
have shown that much of the IR excess originates in sources unrelated to
circumstellar disks.
