Unlock the secrets of exoplanets with our Radial Velocity Calculator. This tool helps you discover the minimum mass of an exoplanet (Mp sin i) by inputting its host star's mass, orbital period, and the observed radial velocity semi-amplitude (K). An essential resource for astrophysics enthusiasts!
Formula:
To calculate the minimum mass of an exoplanet (Mp sin i), we use the formula based on the stellar radial velocity semi-amplitude:Mp sin i = K × (P / (2πG))1/3 × (Ms)2/3
Where:
- Mp sin i: Minimum mass of the exoplanet (result in Jupiter Masses)
- K: Radial velocity semi-amplitude of the host star (m/s)
- P: Orbital period of the exoplanet (days)
- Ms: Mass of the host star (Solar Masses)
- G: Gravitational constant (6.67430 × 10-11 m3 kg-1 s-2)
- 2π: Two times Pi (approximately 6.283185)
