sci.Hertzsprung-Russell-position Calculator
Calculates a star's absolute magnitude and position on the Hertzsprung-Russell diagram from luminosity and effective temperature or spectral class. The main sequence runs from blue (O-type, 30,000 K) to red (M-type, 3,000 K) — 90% of stars spend most of their lives on the main sequence burning hydrogen.
Inputs
L Solar
Reference formula or conversion factor shown for context.
Teff K
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Distance Pc
Separation between two points or total path length. Check that units are consistent throughout the calculation.
