A Pan-STARRS Search for Distant Planets: Part 1

Matthew J. Holman, Kevin J. Napier, Matthew J. Payne +1

We present a search for distant planets in Pan-STARRS1. We calibrated our search by injecting an isotropic control population of synthetic detections into Pan-STARRS1 source catalo…

Sorcha: Optimized Solar System Ephemeris Generation

Matthew J. Holman, Pedro H. Bernardinelli, Megan E. Schwamb +14

Sorcha is a solar system survey simulator built for the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) and future large-scale wide-field surveys. Over the ten-y…

Can Neptune's Distant Mean-Motion Resonances Constrain Undiscovered Planets in the Solar System? Lessons from a Case Study of the 9:1

Matthew W. Porter, David W. Gerdes, Kevin J. Napier +2

Recent observational surveys of the outer Solar System provide evidence that Neptune's distant :1 mean-motion resonances may harbor relatively large reservoirs of trans-Neptunia…

The DECam Ecliptic Exploration Project (DEEP) VI: first multi-year observations of trans-Neptunian objects

Hayden Smotherman, Pedro H. Bernardinelli, Stephen K. N. Portillo +25

We present the first set of trans-Neptunian objects (TNOs) observed on multiple nights in data taken from the DECam Ecliptic Exploration Project (DEEP). Of these 110 TNOs, 105 do n…
