Hydrodynamic Escape Energy-Limited Mass Loss Calculator
Energy-limited XUV escape using same absorption/potential radius, independently established efficiency/Roche correction; no radiative/recombination limitation or hydrodynamic solver.
Description
Hydrodynamic Escape Energy-Limited Mass Loss Calculator: return conditional mass loss kg per s.
An energy-limited atmospheric-loss estimate balances supplied heating energy against gravitational binding. Its efficiency and geometric corrections are model inputs.
This tool returns conditional mass loss kg per s. 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.
Return efficiency times π times absorption radius cubed times XUV flux, divided by G times planet mass times the Roche correction.1

}Limitations and assumptions
- The result depends on the energy-limited approximation and does not solve atmospheric flow, chemistry or evolving irradiation.
- 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.
