Changes in Pluto's Atmosphere Based on Stellar Occultation Data from 2017 to 2023
Amanda A. Sickafoose, Michael J. Person, Carlos A. Zuluaga +14
Pluto's tenuous atmosphere has bar-level pressure and is composed primarily of , with a variable haze. Its eccentric orbit combined with high obliquity leads to si…
Material Around the Centaur (2060) Chiron from the 2018 November 28 UT Stellar Occultation
Amanda A. Sickafoose, Stephen E. Levine, Amanda S. Bosh +5
A stellar occultation of Gaia DR3 2646598228351156352 by the Centaur (2060) Chiron was observed from the South African Astronomical Observatory on 2018 November 28 UT. Here we pres…
The Formation of Bilobate Comet Shapes through Sublimative Torques
Taylor K. Safrit, Jordan K. Steckloff, Amanda S. Bosh +4
Recent spacecraft and radar observations have found that ~70 percent of short-period comet nuclei, mostly Jupiter-family comets (JFCs), have bilobate shapes (two masses connected b…
The Sublimative Evolution of (486958) Arrokoth
Jordan K. Steckloff, Carey M. Lisse, Taylor K. Safrit +3
We consider the history of New Horizons target (486958) Arrokoth in the context of its sublimative evolution. Shortly after the Sun's protoplanetary disk (PPD) cleared, the newly i…
Size and Shape Constraints of (486958) Arrokoth from Stellar Occultations
Marc W. Buie, Simon B. Porter, Peter Tamblyn +130
We present the results from four stellar occultations by (486958) Arrokoth, the flyby target of the New Horizons extended mission. Three of the four efforts led to positive detecti…
Characterization of material around the centaur (2060) Chiron from a visible and near-infrared stellar occultation in 2011
A. A. Sickafoose, A. S. Bosh, J. P. Emery +6
The centaur (2060) Chiron has exhibited outgassing behaviour and possibly hosts a ring system. On 2011 November 29, Chiron occulted a fairly bright star (R approximately 15 mag) as…
