Two new papers dropped last week on the interstellar object. The Paris Observatory team (Biver et al.) pointed Europe's largest millimeter telescope at 3I at peak output. The gas is moving at half the speed every comet at that distance produces.
The bigger find: The gas moves faster toward the Sun than away from it. On every natural object ever observed, the hot side pushes gas outward. 3I pushes into the heat source.
The same team found sulfur compounds essentially missing from the exhaust while carbon and oxygen compounds are concentrated. Sulfur poisons catalysts, reactors, and engines. It is the first thing you remove when refining fuel.
A separate team in Japan (Shinnaka et al.) tracked the carbon dioxide signature on the outbound leg. Still elevated.
The object is heading away from the Sun and the drive has not stopped.
