Ever wondered about the theoretical Kelvin-Helmholtz timescale for a self-gravitating object? This calculator estimates how long a celestial or hypothetical body, including any 'body mass' you input, could sustain its luminosity through gravitational contraction. Input mass, radius, and power output to explore this fascinating astrophysical principle.
Formula:
The Kelvin-Helmholtz Time Scale (τKH) is calculated using the formula:
τKH = (G × M2) / (R × L)
- τKH: Kelvin-Helmholtz Time Scale (in seconds)
- G: Gravitational Constant (approximately 6.674 × 10-11 N m2/kg2)
- M: Body Mass (in kilograms, kg)
- R: Body Radius (in meters, m)
- L: Luminosity or Power Output (in Watts, W)
