Atmospheric Escape Jeans Parameter Escape Flag Checker
Exobase Jeans binding parameter for actual particle mass/temperature, caller low-lambda flag; not atmospheric-loss lifetime or habitability determination.
Description
Atmospheric Escape Jeans Parameter Escape Flag Checker: return jeans parameter, caller low lambda review.
The Jeans parameter compares gravitational binding per particle with thermal energy at the exobase. A chosen review threshold is separate from that calculated parameter.
This tool returns jeans parameter, caller low lambda review. Use the stated units and model convention when interpreting these fields.
When to use this tool
Use this tool when the supplied inputs match the specific operation described above and you need a repeatable result under its stated convention.
- Check the supported input and output contract against an existing calculation or observation.
- Use the complete example to confirm units, selector spelling and result interpretation.
How to use the tool and how it works
- Enter every field in the input table using the stated units and the exact supported selector spelling where applicable.
- Run the tool. Correct input errors before interpreting an output.
- Read the result fields below; use accompanying flags and the stated sign, boundary or model convention when interpreting a number.
Compute G times body mass times particle mass divided by kB, exobase temperature and radius. Flag a value strictly below callerReviewLambda.1
| Input field | Meaning and units | Accepted input |

| exobaseTemperatureK | Exobase temperature k. Kelvin. | Finite number |
| callerReviewLambda | Caller review lambda. | Finite number |
| Output field | Interpretation |
|---|---|
| result | Object containing the following named result fields. |
| result.jeansParameter | Jeans parameter; use the stated units and sign convention. |
| result.callerLowLambdaReview | Caller low lambda review flag under the exact conditions described above. |

}Limitations and assumptions
- The threshold is supplied by the caller. The result is not a full atmospheric escape-rate solution.
- Every declared field is required and unexpected fields are rejected. Numeric inputs must be finite; input errors are distinct from a valid false result or an explicitly qualified output.
- Extremely large inputs and nonfinite or excessively large outputs are rejected. List positions reported by the tool use zero-based indices unless stated otherwise.
Alternative or Complementary methods
Check the underlying observations, units and conventions independently before using the result in a larger workflow. The tools listed below address nearby tasks; compare their inputs and scope before substituting one for this operation.
