Logos-Zoe: A Contact Binary Triple System in the Trans-Neptunian Belt

The Astronomical Journal
The trans-Neptunian object (58534) 1997 CQ _29 (a.k.a. Logos) is a resolved wide binary in the dynamically Cold Classical population. With Hubble Space Telescope resolved observations where the primary Logos is well separated from its secondary Zoe it ...

The scattered trans-Neptunian object 1998 XY95

, 2001
On 1998 December 12 a new trans-Neptunian object, 1998 XY95, was discovered as part of a deep search. Recent observations of this object have placed it amongst the class of objects known as the scattered trans-Neptunian objects (TNOs).

Detection of two binary trans-Neptunian objects, 1997 CQ29 and 2000 CF105, with the Hubble Space Telescope [PDF]

, 2002
Images of the trans-Neptunian objects 1997 CQ29 and 2000 CF105 obtained with the Hubble Space Telescope WFPC2 camera show them to be binary. The two components of 1997 CQ29 were separated in our images by 020 ± 003 in 2001 November and by 033 ± 001 in ...

Synchronous Rotation in the (120347) Salacia–Actaea System

The Planetary Science Journal
We report on roughly 16 yr of photometric monitoring of the trans-Neptunian binary system (120347) Salacia–Actaea, which provides significant evidence that Salacia and Actaea are tidally locked to the mutual orbital period in a fully synchronous ...

Generation of Low-inclination, Neptune-crossing Trans-Neptunian Objects by Planet Nine

The Astrophysical Journal Letters
The solar system’s distant reaches exhibit a wealth of anomalous dynamical structure, hinting at the presence of a yet-undetected, massive trans-Neptunian body—Planet Nine (P9).

FindPOTATOs: Minor Planet Observation Linking Software

The Planetary Science Journal
For minor planet observations to be archived and used by the scientific community, observations of individual objects must be linked together into groups called tracklets.

Detection of Close Kuiper Belt Binaries with HST WFC3

The Planetary Science Journal
Binaries in the Kuiper Belt are common. Here we present our analysis of the Solar System Origins Legacy Survey (SSOLS) to show that using a point-spread function (PSF)-fitting method can roughly double the number of binaries identified in that data set ...

The Luminosity Function of Ultrafaint Trans-Neptunian Objects Detected by JWST

The Astronomical Journal
We present a definitive discovery of 27 trans-Neptunian objects (TNOs) using the Near-Infrared Camera aboard the James Webb Space Telescope (JWST). By employing a shift-and-stack technique and a machine learning network geared specifically to identifying
