Summary if I may: A new paper submitted by the author and Thiem Hoang challenges the recent findings in Nature by Jennifer Bergner and Darryl Seligman about the surface temperature of Oumuamua. The paper claims that Bergner and Seligman miscalculated the temperature by ignoring the cooling effect of evaporating hydrogen. Correcting this oversight reduces the surface temperature by an order of magnitude and makes their model untenable. The author also highlights how Oumuamua lacks the visible cometary tail of gas and dust that characterizes all known comets, further challenging its classification as a generic comet.
