isotropic stellar luminosity from flux calculator online

Use isotropic stellar luminosity from flux online for flux W m2, distance pc. Idealized astronomical model with displayed units. Seeing, extinction, instrument losses or cosmological effects apply only when explicitly included.

How to use it

Enter flux W m2. Set distance pc. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
flux W m2Main input. Positive values. 1e-10
distance pcOption. Positive values. 10

Calculation method

luminosity_W = 4*pi*(distance_pc*3.085677581491367e16)^2*flux_W_m2 (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply isotropic stellar luminosity from flux to the case below, keeping the displayed units and assumptions. Idealized astronomical model with displayed units. Seeing, extinction, instrument losses or cosmological effects apply only when explicitly included.

Isotropic Stellar Luminosity from Flux — worked case

Settings: distance pc: 10

Input:

1e-10

Calculated result for these inputs:

Output:

{
  "luminosity_W": 1.1964951828635062e+26
}

Choose the right tool

Use telescope calculators for focal lengths and angular scale, magnitude tools for logarithmic brightness relationships, and orbit tools for the specified gravitational model. Check whether a distance is in parsecs, light-years or astronomical units.

Limitations and common mistakes

  • Idealized astronomical model with displayed units. Seeing, extinction, instrument losses or cosmological effects apply only when explicitly included.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
