Habitable Zone Inner Edge Calculator
Caller spectrum/model independently verified two effective-flux boundaries; conditional HZ distance interval, not planet habitability or fixed universal solar limits. Model only, not an ephemeris, measured stellar identity or observational guarantee.
Description
Habitable-zone distances depend on independently chosen effective-flux limits.
Habitable-zone distances depend on independently chosen effective-flux limits.1
A flux-based interval does not establish actual habitability or atmospheric conditions. Use Habitable Zone Inner Edge Calculator to evaluate the supplied inputs under the model explained below.
When to use Habitable Zone Inner Edge Calculator
Use Habitable Zone Inner Edge Calculator to evaluate the supplied inputs under the model explained below. Establish the units, measurement scope and model assumptions before entering values.
How to use Habitable Zone Inner Edge Calculator and understand its results
- Establish the units, measurement scope and model assumptions before entering values.
- Enter Stellar luminosity solar, Caller inner effective flux solar, Caller outer effective flux solar using the field table and validation rules below, then run the tool.
- Read Conditional inner au, Conditional outer au; interpret the units, signs, ordering and unknown-value placeholders described below.
- Correct reported input errors and rerun. Apply successful results according to their specific meanings and check the assumptions before using them in a decision.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| stellarLuminositySolar | Stellar luminosity solar | number | Required; constraints below |
| callerInnerEffectiveFluxSolar | Caller inner effective flux solar | number | Required; constraints below |
| callerOuterEffectiveFluxSolar | Caller outer effective flux solar | number | Required; constraints below |
Enter nonnegative luminosity in solar units and positive caller inner and outer effective-flux limits, with inner flux strictly above outer. Return sqrt(luminosity/innerFlux) and sqrt(luminosity/outerFlux) in AU. Zero luminosity returns both zero. No installed climate criterion, spectrum correction or habitability determination occurs.
innerAu=sqrt(luminositySolar/innerEffectiveFlux); outerAu=sqrt(luminositySolar/outerEffectiveFlux) Use the field order, units and branch conditions described above.
| Output field | Meaning | Value type |
|---|---|---|
| conditionalInnerAu | Conditional inner au | number |
| conditionalOuterAu | Conditional outer au | number |

}Limitations and assumptions
A flux-based interval does not establish actual habitability or atmospheric conditions. Apply the exact scope and assumptions explained above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are explained above; extremely large inputs or outputs can also be rejected. Input errors differ from successful false results, empty match lists and unknown-evidence placeholders.
