Spectroscopy and thermal modelling of the first interstellar object 1I/2017 U1 'Oumuamua
Alan Fitzsimmons, Colin Snodgrass, Ben Rozitis et al., 2018. Nature Astronomy.
Optical spectra from the William Herschel and Palomar telescopes showing a featureless red slope, and a thermal model showing that an insulating, organic-rich mantle half a metre thick could have kept interior ices from sublimating during the perihelion passage. Nature Astronomy 2, 133-137.
What it's used for here
The surface composition evidence and the mantle argument used by several later explanations.
