The atmospheric compositions ruled out by the Tiberius dataset binned at 60 pixels. In all sub-figures, the y-axis indicates the pressure at the top of an infinitely opaque layer (i.e.,

The instantaneous Vtid on Proxima b at periastron (a) and at apastron (b), and the orbital-mean amplitude of tidal potential (Vtid) on Proxima b (c) and on Earth (d). —

The g-r vs. r-i colours of 3I/ATLAS from our measurements compared with solar system objects and other ISOs (Meech et al. 2017; Bolin et al. 2020). We use the scheme

Oblique view of part of a system of FSRs, recording multiple river tributaries, likely all active at the same or similar times. This shows rivers meandering, areas where river banks
