Exoplanet Transit Depth Percent
Unblended fully contained opaque planet across uniformly bright stellar disk; grazing, limb darkening and dilution external. Model only, not an ephemeris, measured stellar identity or observational guarantee.
Description
An ideal opaque transit blocks a fraction of a uniformly bright stellar disk.
An ideal opaque transit blocks a fraction of a uniformly bright stellar disk.1
The area ratio omits limb darkening, grazing geometry and contamination. Use Exoplanet Transit Depth Percent to evaluate the supplied inputs under the model explained below.
When to use Exoplanet Transit Depth Percent
Use Exoplanet Transit Depth Percent to evaluate the supplied inputs under the model explained below. Establish the units, measurement scope and model assumptions before entering values.
How to use Exoplanet Transit Depth Percent and understand its results
- Establish the units, measurement scope and model assumptions before entering values.
- Enter Planet radius same units, Star radius same units using the field table and validation rules below, then run the tool.
- Read Uniform disk transit depth percent; 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 |
|---|---|---|---|
| planetRadiusSameUnits | Planet radius same units | number | Required; constraints below |
| starRadiusSameUnits | Star radius same units | number | Required; constraints below |
Enter nonnegative planet radius and positive star radius in the same units, with planet≤star. Return 100×(planet/star)² as percent depth. Zero planet gives 0; equality gives 100. No limb darkening, impact parameter or dilution is included.
uniformDiskTransitDepthPercent=100×(planetRadius/starRadius)² Use the field order, units and branch conditions described above.
| Output field | Meaning | Value type |
|---|---|---|
| uniformDiskTransitDepthPercent | Uniform disk transit depth percent | number |

}Limitations and assumptions
The area ratio omits limb darkening, grazing geometry and contamination. 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.
