WebJun 13, 2016 · We present a measurement of H2O ice crystallinity on the surface of trans-neptunian objects (TNOs) with near-infrared narrow-band imaging. The newly developed photometric technique allows us to efficiently determine the strength of an 1.65-um absorption feature in crystalline H2O ice. WebThe detection of crystalline H2O-ice on multiple surfaces of Kuiper Belt Objects (KBOs) seems to contrast with what scientists understand about the surface environment of these objects, as previous estimates suggest that radiolysis should have easily amorphized these objects’ surface over their lifetimes. Here, we use a detailed
