# Implications of Evaporative Cooling by H2 for 1I/'Oumuamua

Thiem Hoang, Abraham Loeb, 2023. _The Astrophysical Journal Letters_.

Argues that Bergner and Seligman neglected the cooling of the surface by the escaping hydrogen, which would lower the surface temperature by about a factor of nine and the volume of ice warm enough to release hydrogen by a factor of five to nine, leaving too little gas. ApJL 951, L34.
