----- Attempting Submission 19 (Mon Sep 16 20:41:04 GMT 2024) -----Visit and Orbit planner have been ranA Deep Search for Moons around Contact Binary Trans-Neptunian Objects.A close/contact binary can be a small body with a bi-lobed shape (like 67P/Churyumov-Gerasimenko visited by the European Space Agency's Rosetta mission) or two objects touching in one point, as well as two objects with a small separation of less than a few hundred kilometers. The flyby of the trans-Neptunian object Arrokoth (a.k.a (486958) 2014 MU69) by the NASA New Horizons spacecraft has left us with no doubt that contact binaries do exist in the trans-Neptunian belt. Unfortunately, it is still unclear how these objects can form at the edge of our Solar System. Several models have been proposed, but none have been thoroughly tested with observations as the contact binary population remained elusive until recently. We propose a deep search for moon(s) around likely/confirmed contact binary identified through lightcurve and stellar occultation observations. The fraction of systems with/without a moon will allow us to infer which proposed formation model (if any) is more likely to reproduce the current contact binary population. These observations will (1) provide context for the New Horizons flyby of Arrokoth, (2) provide constraints for planetesimal formation, and (3) challenge the current formation models for binary/multiple systems.We aim to look for moon(s) around contact binaries in the trans-Neptunian belt to constrain the formation of these systems.Dr. Audrey Thirouin and Dr. Scott S. Sheppard have expertise in data aquisition and data reduction for rotational and physical properties of trans-Neptunian objects and other small bodies in our Solar System. They also have discovered and characterized most of the contact binaries in the trans-Neptunian belt.
Dr. Keith S. Noll is an expert in HST data reduction and analysis. He has been using HST over the past 25 years to search and characterize moons around trans-Neptunian objects, as well as Trojans (for the Lucy mission) and other small bodies. He was/is the PI of several HST surveys to search for moons.
Team members have enough expertise with the HST data (and data in general) to carry out the proposed work. Also, team members of this proposal have led HST observations that have discovered moons around trans-Neptunian objects using HST in the past. Results from awarded time have been published in several papers, and more papers are in preparation.Solar System Astronomy6falsefalsefalsefalsefalsefalsefalsefalseSUPPORTEDSOLAR SYSTEMNOASTEROID2014JO80TYPE=ASTEROID,A=39.20672801745897,E=0.2915518166373076,I=15.69554391233225
