Hypotheses for Triton's Plumes: New Analyses and Future Remote Sensing Tests
Jason D. Hofgartner, Samuel P. D. Birch, Julie Castillo +14
At least two active plumes were observed on Neptune's moon Triton during the Voyager 2 flyby in 1989. Models for Triton's plumes have previously been grouped into five hypotheses,…
Spatial Distribution of Ultraviolet Emission from Cometary Activity at 67P/Churyumov-Gerasimenko
John W. Noonan, Dominique Bockelée-Morvan, Paul D. Feldman +16
The Alice ultraviolet spectrograph on board the \textit{Rosetta} orbiter provided the first near-nucleus ultraviolet observations of a cometary coma from arrival at comet 67P/Chury…
Analysis of Hybrid Gas-Dust Outbursts Observed at 67P/Churyumov-Gerasimenko
John W. Noonan, Giovanna Rinaldi, Paul D. Feldman +14
Cometary outbursts offer a valuable window into the composition of comet nuclei with their forceful ejection of dust and volatiles in explosive events, revealing the interior compo…
Pluto's Ultraviolet Spectrum, Surface Reflectance, and Airglow Emissions
Andrew J. Steffl, Leslie A. Young, Darrell F. Strobel +16
During the New Horizons spacecraft's encounter with Pluto, the Alice ultraviolet spectrograph conducted a series of observations that detected emissions from both the interplanetar…
Upper Limits for Emissions in the Coma of Comet 67P/Churyumov-Gerasimenko Near Perihelion as Measured by Rosetta's Alice Far-Ultraviolet Spectrograph
B. A. Keeney, S. A. Stern, R. J. Vervack +13
The Alice far-UV imaging spectrograph (700-2050 A) acquired over 70,000 spectral images during Rosetta's 2-year escort mission, including over 20,000 in the months surrounding peri…
Stellar Occultation by Comet 67P/Churyumov-Gerasimenko Observed with Rosetta's Alice Far-Ultraviolet Spectrograph
B. A. Keeney, S. A. Stern, P. D. Feldman +13
Following our previous detection of ubiquitous H2O and O2 absorption against the far-UV continuum of stars located near the nucleus of Comet 67P/Churyumov-Gerasimenko, we present a…
On the possible noble gas deficiency of Pluto's atmosphere
Olivier Mousis, Jonathan I. Lunine, Kathleen E. Mandt +6
We use a statistical-thermodynamic model to investigate the formation and composition of noble-gas-rich clathrates on Pluto's surface. By considering an atmospheric composition clo…
Characterizing CO Fourth Positive Emission in Young Circumstellar Disks
Rebecca Schindhelm, Kevin France, Eric Burgh +5
Carbon Monoxide is a commonly used IR/sub-mm tracer of gas in protoplanetary disks. We present an analysis of ultraviolet CO emission in {HST}-COS spectra for 12 Classical T Tauri…
The Far-Ultraviolet "Continuum" in Protoplanetary Disk Systems II: CO Fourth Positive Emission and Absorption
Kevin France, Rebecca Schindhelm, Eric B. Burgh +21
We exploit the high sensitivity and moderate spectral resolution of the -Cosmic Origins Spectrograph to detect far-ultraviolet spectral features of carbon monoxide (CO) presen…
