Orbit determination service 112 includes an orbit calculator 212 that uses the ranging data to calculate a list of orbital elements. Ground station 104 then provides feedback information back to mission control service 110, which can then use the feedback information to provide information back to ...
This number looks familiar because it is also the orbital velocity and period of an object orbiting at the surface of the Earth, or in low Earth orbit, because in that case centripetal acceleration is counteracting the acceleration due to gravity producing effective weightlessness. To get a cylind...
Other theories posit that planet assembly at small orbital separations may be common6,7,8. Here we report a newly born, transiting planet orbiting its star with a period of 5.4 days. The planet is 50 per cent larger than Neptune, and its mass is less than 3.6 times that of Jupiter (...
We are able to strongly rule out an absolute C/O ≥ 1 scenario (χ2/N ≥ 3.97), which has previously been proposed for gas-dominated accretion at wide orbital radii beyond the CO2ice line at which the gas may be carbon-rich39. Our C/O upper limit, therefore, suggests that ...
The exoplanet discovery calculator allows you to play around and discover the calculations that got a Nobel Prize in 2019 for the discovery of planets outside the solar system.

chromatic_fitting uses the PyMC3 (NUTS) sampler58to fit the exoplanet transit model to the light curves. First, we fit the white-light curves for order 1. The white-light curve was generated using an inverse variance-weighted average of the unbinned data. We fixed the orbital period to ...
noise by binning the data into successively smaller bins (that is, fewer data points per bin) and calculating the signal-to-noise ratio achieved60. Extended Data Fig.4shows the Allan deviation for three of the 11 reductions performed on the data (see the ExoTiC-ISM noise_calculator function...
