Cold traps of hypervolatiles in the protosolar nebula at the origin of the peculiar composition of comet C/2016 R2 (PanSTARRS)
Recent observations of the long-period comet C/2016 R2 (PanSTARRS; hereafter R2)
indicate an unusually high N 2/CO abundance ratio, typically larger than∼ 0.05, and at least …
