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…
Doomed Worlds II: Reassessing Suggestions of Orbital Decay for TrES-5 b
Marvin Rothmeier, Elisabeth R. Adams, Karsten Schindler +9
TrES-5b is one of only three ultra-hot Jupiters (UHJs) with suggestions of a possibly decreasing orbital period that have persisted through multiple independent analyses (G. Maciej…
Metrics for Optimizing Searches for Orbital Precession and Tidal Decay via Transit- and Occultation-Timing
Brian Jackson, Elisabeth R. Adams, Rachel M. Huchmala +4
Short-period exoplanets may exhibit orbital precession driven by several different processes, including tidal interactions with their host stars and secular interactions with addit…
The Near-Centaur Environment: Satellites, Rings, and Debris
A. A. Sickafoose, S. M. Giuliatti Winter, R. Leiva +3
The unexpected finding of a ring system around the Centaur (10199) Chariklo opened a new window for dynamical studies and posed many questions about the formation and evolutionary…
Doomed Worlds I: No new evidence for orbital decay in a long-term survey of 43 ultra-hot Jupiters
Elisabeth R. Adams, Brian Jackson, Amanda A. Sickafoose +8
Ultra-hot Jupiters are likely doomed by tidal forces to undergo orbital decay and eventual disruption by their stars, but the timescale over which this process unfolds is unknown.…
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…
A large topographic feature on the surface of the trans-Neptunian object (307261) 2002 MS measured from stellar occultations
F. L. Rommel, F. Braga-Ribas, J. L. Ortiz +201
This work aims at constraining the size, shape, and geometric albedo of the dwarf planet candidate 2002 MS4 through the analysis of nine stellar occultation events. Using multichor…
Constraints on (2060) Chiron's size, shape, and surrounding material from the November 2018 and September 2019 stellar occultations
Felipe Braga-Ribas, C. L. Pereira, B. Sicardy +24
After the discovery of rings around the largest known Centaur object, (10199) Chariklo, we carried out observation campaigns of stellar occultations produced by the second-largest…
The Nature of Low-Albedo Small Bodies from 3-m Spectroscopy: One Group that Formed Within the Ammonia Snow Line and One that Formed Beyond It
Andrew S. Rivkin, Joshua P. Emery, Ellen S. Howell +9
We present evidence, via a large survey of 191 new spectra along with previously-published spectra, of a divide in the 3-m spectral properties of the low-albedo asteroid populat…
Beyond Gaia: Asteroseismic Distances of M giants using Ground-Based Transient Surveys
Connor Auge, Daniel Huber, Aren Heinze +14
Evolved stars near the tip of the red giant branch (TRGB) show solar-like oscillations with periods spanning hours to months and amplitudes ranging from 1 mmag to 100 m…
Investigating Taxonomic Diversity within Asteroid Families through ATLAS Dual-Band Photometry
N. Erasmus, S. Navarro-Meza, A. McNeill +6
We present here the c-o colors for identified Flora, Vesta, Nysa-Polana, Themis, and Koronis family members within the historic data set (2015-2018) of the Asteroid Terrestrial-imp…
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…
Observational Investigation of the 2013 Near-Earth Encounter by Asteroid (367943) Duende
Nicholas Moskovitz, Conor Benson, Daniel Scheeres +20
On 15 February 2013, the asteroid 367943 Duende (2012 DA14) experienced a near-Earth encounter at an altitude of 27,700 km or 4.2 Earth radii. We present here the results of an ext…
A Taxonomic Study of Asteroid Families from KMTNet-SAAO Multi-band Photometry
N. Erasmus, A. McNeill, M. Mommert +3
We present here multi-band photometry for over 2000 Main-belt asteroids. For each target we report the probabilistic taxonomy using the measured V-R and V-I colors in combination w…
