Questions3I/ATLASWhy did nickel vapour appear around 3I/ATLAS without iron, so far from the Sun?Answer
Answer · 3I/ATLAS
A short-lived heat source released the early nickel
The early excess of nickel came from a brief heat source at 100 to 140 K, possibly amorphous water ice turning crystalline, on top of the steady carbonyl release.
Where it stands
Still possibleOne piece of evidence for, none against. It needs two reviews to be accepted.
What it predicts
- Crystalline ice appears in the dust after the transition
- No second nickel excess on the outbound leg at the same temperatures
What would rule it out
- A carbonyl model alone fits the inbound nickel curve
