We present results from a new pipeline custom-designed to search for faint, undiscovered solar system bodies using full-frame image data from the NASA Transiting Exoplanet Survey Satellite (TESS) mission. This pipeline removes the baseline flux of each pixel before aligning and coadding frames along plausible orbital paths of interest. We first demonstrate the performance of the pipeline by recovering the signals of three trans-Neptunian objects—90377 Sedna (V = 20.64), 2015 BP519 (V = 21.81…

Peculiar orbits and asymmetries in extreme trans-Neptunian space
It is still an open question how the Solar system is structured beyond 100 au from the Sun. Our understanding of this vast region remains very limited and only recently we have become aware of the


Discovery and Dynamical Analysis of an Extreme Trans-Neptunian Object with a High Orbital Inclination
We report the discovery and dynamical analysis of 2015 BP519, an extreme trans-Neptunian object (TNO) detected by the Dark Energy Survey at a heliocentric distance of 55 au, perihelion of ∼36 au, and
The Solar System Beyond Neptune
The aim of this research is to study the objects in the Kuiper Belt, in order to understand the nature of its origin and the evolutionary processes which have affected the Kuiper Belt. Particular
Physical Properties of Kuiper Belt and Centaur Objects: Constraints from the Spitzer Space Telescope
Detecting heat from minor planers in the outer solar system is challenging, yet it is the most efficient means for constraining the albedos and sizes of Kuiper belt objects (KBOs) and their progeny,

Solar System Objects Observed with TESS—First Data Release: Bright Main-belt and Trojan Asteroids from the Southern Survey
Compared with previous space-borne surveys, the Transiting Exoplanet Survey Satellite (TESS) provides a unique and new approach to observe solar system objects. While its primary mission avoids the
A TESS Search for Distant Solar System Objects: Yield Estimates
The yield for such a survey is estimated and it is demonstrated that `digital tracking' techniques can be used to efficiently `shift-and-stack' TESS full frame images (FFIs) and has the potential to discover hundreds of Kuiper Belt Objects, Scattered Disk Objects and Centaurs in TESS FFI data.

The Transiting Exoplanet Survey Satellite (TESS) searches for planets transiting bright and nearby stars using high-cadence, large-scale photometric observations. Full frame images provided by the
A TESS Search for Distant Solar System Planets: A Feasibility Study
As the NASA Transiting Exoplanet Survey Satellite (TESS) fulfills its primary mission it is executing an unprecedented all-sky survey with the potential to discover distant planets in our own solar
Hidden Planets: Implications from ’Oumuamua and DSHARP
The discovery of ’Oumuamua (1I/2017 U1), the first interstellar interloper, suggests an abundance of free-floating small bodies whose ejection into galactic space cannot be explained by the current
