The DECam Ecliptic Exploration Project (DEEP): Early Results from the Main Asteroid Belt

The DECam Ecliptic Exploration Project (DEEP) is a wide-field survey of the trans-Neptunian solar system. DEEP has also obtained fast-cadence photometry for many Main-Belt Asteroids (MBAs) to a limiting magnitude of VR~23.5. DEEP has measured lightcurves of more than 60,000 MBAs. We present our first results from the analysis of these MBA lightcurves, and their implications for MBA physical characteristics and the evolution of the solar system as a whole. We discuss the discovery and characterization of many unusual MBA types found within the DEEP data, super-fast rotators (SFRs), contact binaries, and eclipsing binary asteroids. All three categories are rare in the main belt, and all provide powerful probes of the internal properties and evolution of asteroids. Additionally, we present bulk physical characteristics of the Main Belt and the shape distribution of MBAs compared to near-Earth objects.

These data were obtained on the Blanco telescope at Cerro Tololo Inter-American Observatory (CTIO), with observations supported by NOIRLab and the NSF. We thank the CTIO staff for their exceptional help with obtaining this data. This work is supported by NASA grant NNX17AF21G and NSF under grants No. AST-2009096 and AST-1409547.
