We have determined the mineralogical composition of dust in the Broad Absorption Line (BAL) quasar PG 2112+059 using mid-infrared spectroscopy obtained with the Spitzer Space Teles…
The population of propellers in Saturn's A Ring
Matthew S. Tiscareno, Joseph A. Burns, Matthew M. Hedman +1
We present an extensive data set of ~150 localized features from Cassini images of Saturn's Ring A, a third of which are demonstrated to be persistent by their appearance in multip…
New Horizons: Anticipated Scientific Investigations at the Pluto System
Leslie A. Young, S. Alan Stern, Harold A. Weaver +24
The New Horizons spacecraft will achieve a wide range of measurement objectives at the Pluto system, including color and panchromatic maps, 1.25-2.50 micron spectral images for stu…
