R. Hajian is an astronomer at the U.S.
Naval Observatory in Washington, DC. He joined
the scientific staff at the USNO Department of Astrometry
in 1995, after completing his doctorate at Cornell
University under the direction of Yervant Terzian.
In addition to his research in planetary nebulae
and the physics of the interstellar medium, Arsen's
areas of active astrophysical research include spatial
optical interferometry, and precise interferometric
spectroscopy. He can sometimes be found at Anderson
Mesa, outside Flagstaff, Arizona, working with the
Prototype Optical Interferometry project, which
is measuring stellar positions and diameters and
splitting double stars with unprecedented accuracy.
Arsen is also completing the construction of a Fourier
Transform Spectrometer with which he hopes to detect
planets as small as the Earth in orbit about other
Arsen and his wife, Jenepher, celebrated the birth
of their son Krikor in January 2000.
