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…
