Celestial mechanics, orbits, transits and radiation.
- Exoplanet transit: light curve, depth and durationsLight curve of an exoplanet transit: depth, T14 and T23 durations and shape of the floor, with limb darkening.Provisional
- Hohmann transfer: Δv, transfer time and departure windowThe two impulses of a transfer between circular orbits, the total Δv, the duration, the phase angle at departure, and the bi-elliptic threshold.Provisional
- Keplerian orbit: position, velocity and the law of areasThe exact state of a body on its ellipse at time t: Kepler’s equation, vis-viva, apsides, law of areas and the invariants h and ε.Provisional
- Lagrange points: the five equilibria and the forbidden regionsThe five equilibrium points of a rotating pair, their Jacobi constants and the regions forbidden to the third body at a given constant.Provisional
- Stellar radial velocity: curve, semi-amplitude K and minimum massThe radial velocity curve of a star with a planet, its semi-amplitude K, the minimum mass m sin i, and how it compares with a spectrograph’s precision.Provisional
