On the Nature of the Dust in the Debris Disk Around HD69830
C. M. Lisse, C. A. Beichman, G. Bryden +1
We have used the infrared mineralogical model derived from the Spitzer IRS observations of the Deep Impact experiment to study the nature of the dust in the debris found around the…
Transience of hot dust around sun-like stars
M. C. Wyatt, R. Smith, J. S. Greaves +3
There is currently debate over whether the dust content of planetary systems is stochastically regenerated or originates in planetesimal belts evolving in steady state. In this pap…
Hubble Space Telescope Observations of Comet 9P/Tempel 1 during the Deep Impact Encounter
Paul D. Feldman, Stephan R. McCandliss, Matthew Route +4
We report on the Hubble Space Telescope program to observe periodic comet 9P/Tempel 1 in conjunction with NASA's Deep Impact mission. Our objectives were to study the generation an…
Generation of Entangled Photon Holes using Quantum Interference
T. B. Pittman, J. D. Franson
In addition to photon pairs entangled in polarization or other variables, quantum mechanics also allows optical beams that are entangled through the absence of the photons themselv…
Carbon Monoxide in Comet 9P/Tempel 1 before and after the Deep Impact Encounter
Paul D. Feldman, Roxana E. Lupu, Stephan R. McCandliss +4
One of the goals of the Hubble Space Telescope program to observe periodic comet 9P/Tempel 1 in conjunction with NASA's Deep Impact mission was to study the generation and evolutio…
CO emission from candidate photo-dissociation regions in M81
J. H. Knapen, R. J. Allen, H. I Heaton +2
Context At least a fraction of the atomic hydrogen in spiral galaxies is suspected to be the result of molecular hydrogen which has been dissociated by radiation from massive stars…
