Over the past half century, astronomers have identified on the order of 2000 Very Metal Poor (VMP) stars with [Fe/H] -2.0, and a few hundred Extremely Metal...
The primary goal of this project is to characterize the surface composition (and other properties such as radius, albedo and thermal inertia) of a sample of low...
We present initial results from a study of a sample of low-perihelion near-Earth asteroids (NEAs) using the Infrared Spectrograph (IRS) on NASA’s Spitzer Space...
This is a progress report on a project to characterize the surface composition (and other properties such as radius, albedo and thermal inertia) of a sample of...
Low resolution mapping of Comet Halley in principal atomic and molecular species
Maps of a 3 by 2 arcmin region of the inner coma of comet Halley, at 10 arcsec resolution, in several principal atomic and molecular species were prepared by...
Low resolution mapping of Comet Halley in the near infrared
The authors present low resolution maps, of a four by one half arcminute region, of comet Halley, in photometric bands J and K, and central scan in the H band...
