sci.binary-star-orbital Calculator
Calculates binary star orbital parameters (period, semi-major axis, masses) from observed radial velocities and light curves using Kepler's third law. From a binary's orbital period and velocity amplitude, both stellar masses can be determined — this is the primary method of direct stellar mass measurement.
Inputs
Period Years
Time for one complete cycle (s). Period = 1 / frequency. A 50 Hz signal has a 20 ms period.
Semimajor Axis Au
Reference formula or conversion factor shown for context.
Mass1 Solar
Total mass (kg). Distinct from weight — weight = mass × gravity. Mass is constant; weight varies with location.
Mass2 Solar
Total mass (kg). Distinct from weight — weight = mass × gravity. Mass is constant; weight varies with location.
Results
total mass from Kepler (M☉)
The combined total across all inputs and components.
mass ratio M1/M2
The proportional relationship between two quantities.
star 1 orbit radius (AU)
The computed radius -- half the diameter.
star 2 orbit radius (AU)
The computed radius -- half the diameter.
Kepler: M_tot = a³/P² (M☉,AU,yr)
