The size and mass distribution of cold classical TNOs for

Gary M. Bernstein, Wesley C. Fraser, Marielle R. Eduardo +7

The cold classical trans-Neptunian objects (CCs) are the only observable \textit{in situ} population of planetesimal remnants believed to have escaped collisional grinding. Recent…

The Luminosity Function of Ultra-Faint Trans-Neptunian Objects Detected by JWST

Marielle R. Eduardo, Anastasia N. Morgan, Wesley C. Fraser +8

We present a definitive discovery of 27 trans-Neptunian objects (TNOs) using the Near-Infrared Camera (NIRCam) aboard the James Webb Space Telescope (JWST). By employing a shift-an…

Combined JWST and HST Deep Imaging to Characterize the Smallest Known Trans-Neptunian Objects

Anastasia N. Morgan, Marielle R. Eduardo, David E. Trilling +9

We present optical-near-infrared (NIR) color measurements for small ( km) Trans-Neptunian Objects (TNOs) using coordinated and nearly simultaneous observations from the Ja…

Col-OSSOS: Investigating the Origins of Different Surfaces in the Primordial Kuiper Belt

Laura E. Buchanan, Megan E. Schwamb, Wesley C. Fraser +12

The Colours of the Outer Solar System Origins Survey (Col-OSSOS) measured the optical/NIR colours of a brightness-complete sample of Trans-Neptunian Objects (TNOs). Like previous s…

Hunting for Hydrated Minerals on Trans-Neptunian Objects

Tom Seccull, Wesley C. Fraser, Dominik A. Kiersz +1

We present new optical reflectance spectra of three potentially silicate-rich trans-Neptunian Objects (TNOs). These spectra were obtained with the aim of confirming past hints and…
