Could Tidal-Disruption Fragments Explain Oumuamua’s Elongated Interstellar Voyage?
To the point
Yun Zhang and Doug Lin propose that Oumuamua is a long, thin fragment ripped from a world shredded by a star in another system, launched by tidal disruption, whose surface melting and pockets of ice could drive jets to explain its acceleration and a crust that forms as it resolidifies to make it durable, while some scientists favor a pancake shape like Arrokoth over a cigar shape, keeping the origin open.
