Orbital Characterization of a Newly Discovered Small Satellite Around Quaoar
Benjamin Proudfoot, Richard Nolthenius, Bryan J. Holler +5
Recent observations of a stellar occultation have revealed the presence of a previously undiscovered small satellite around Quaoar. Orbiting near Quaoar's unusual ring system, this…
Synchronous Rotation in the (120347) Salacia-Actaea System
Cameron Collyer, Estela Fernandez-Valenzuela, Jose Luis Ortiz +8
We report on roughly 16 years of photometric monitoring of the transneptunian binary system (120347) Salacia-Actaea which provides significant evidence that Salacia and Actaea are…
Prediction and observation of a stellar occultation by Haumea's satellite Namaka
F. L. Rommel, B. C. N. Proudfoot, B. J. Holler +2
Stellar occultations are an ideal way to characterize the physical and orbital properties of trans-Neptunian binary systems. In this research note, we detail the prediction and obs…
Cross validation of albedo determination for 1627 Ivar from three different techniques
Elena Selmi, M. Devogèle, J. R. Masiero +10
Near Earth Asteroids are of great interest to the scientific community due to their proximity to Earth, making them both potential hazards and possible targets for future missions,…
Prominent mid-infrared excess of the dwarf planet (136472) Makemake discovered by JWST/MIRI indicates ongoing activity
Csaba Kiss, Thomas G. Müller, Anikó Farkas-Takács +18
We report on the discovery of a very prominent mid-infrared (18-25 μm) excess associated with the trans-Neptunian dwarf planet (136472) Makemake. The excess, detected by the MIRI i…
Physical properties of Centaur (60558) 174P/Echeclus from stellar occultations
C. L. Pereira, F. Braga-Ribas, B. Sicardy +42
The Centaur (60558) Echeclus was discovered on March 03, 2000, orbiting between the orbits of Jupiter and Uranus. After exhibiting frequent outbursts, it also received a comet desi…
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…
The LCO Outbursting Objects Key Project: Overview and Year 1 Status
Tim Lister, Michael S. P. Kelley, Carrie E. Holt +32
The LCO Outbursting Objects Key (LOOK) Project uses the telescopes of the Las Cumbres Observatory (LCO) Network to: (1) to systematically monitor a sample of Dynamically New Comets…
The 2017 May 20 stellar occultation by the elongated centaur (95626) 2002 GZ
P. Santos-Sanz, J. L. Ortiz, B. Sicardy +56
We predicted a stellar occultation of the bright star Gaia DR1 4332852996360346368 (UCAC4 385-75921) (m= 14.0 mag) by the centaur 2002 GZ for 2017 May 20$^{\rm th}…
Compositional study of trans-Neptunian objects at λ > 2.2 μm
E. Fernández-Valenzuela, N. Pinilla-Alonso, J. Stansberry +12
Using data from the Infrared Array Camera on the Spitzer Space Telescope, we present photometric observations of a sample of 100 trans-Neptunian objects (TNOs) beyond 2.2 μm. These…
Spitzer's Solar System Science Legacy: Studies of the Relics of Solar System Formation & Evolution. Part 1 - Comets, Centaurs, & Kuiper Belt Objects
Carey Lisse, James Bauer, Dale Cruikshank +15
In its 16 years of scientific measurements, the Spitzer Space Telescope performed a number of ground breaking and key infrared measurements of Solar System objects near and far. Ta…
The size, shape, density and ring of the dwarf planet Haumea from a stellar occultation
J. L. Ortiz, P. Santos-Sanz, B. Sicardy +90
Among the four known transneptunian dwarf planets, Haumea is an exotic, very elongated, and fast rotating body. In contrast to the other dwarf planets, its size, shape, albedo, and…
The large Trans-Neptunian Object 2002 TC from combined stellar occultation, photometry and astrometry data
