The Solar Wind Around Pluto (SWAP) Instrument Aboard New Horizons
D. McComas, F. Allegrini, F. Bagenal +15
The Solar Wind Around Pluto (SWAP) instrument on New Horizons will measure the interaction between the solar wind and ions created by atmospheric loss from Pluto. These measurement…
Cool Stars in Hot Places
S. T. Megeath, E. Gaidos, J. J. Hester +4
During the last three decades, evidence has mounted that star and planet formation is not an isolated process, but is influenced by current and previous generations of stars. Altho…
Chandra Observations of Supernova 1987A
Sangwook Park, David N. Burrows, Gordon P. Garmire +3
We have been monitoring Supernova (SN) 1987A with {\it Chandra X-Ray Observatory} since 1999. We present a review of previous results from our {\it Chandra} observations, and some…
A Mid-Infrared Spitzer Study of the Herbig Be Star R Mon and the Associated HH 39 Herbig-Haro Object
M. Audard, S. Skinner, M. Guedel +3
We report on initial results of our Spitzer Cycle 2 program to observe the young massive star R Mon and its associated HH 39 Herbig-Haro object in the mid-infrared. Our program use…
Is There Enhanced Depletion of Gas-Phase Nitrogen in Moderately Reddened Lines of Sight?
Adam G. Jensen, Brian L. Rachford, Theodore P. Snow
We report on the abundance of interstellar neutral nitrogen (NI) for 30 sightlines, using data from the Far Ultraviolet Spectroscopic Explorer (FUSE) and the Hubble Space Telescope…
He II Reionization and Sources of Metagalactic Ionization
J. Michael Shull
Intergalactic Ly-alpha opacity suggests that H I was reionized at z ~ 6, while He II reionization was delayed to z ~ 3. Both epochs are in conflict with inferences from CMB optical…
