2018-05-20 · The radial velocity method PLATOMission on 20/05/2018 / Comments closed Ground-based radial velocity measurements of candidate planets detected by PLATO will be carried out to confirm or reject the planet detection and to determine the planet mass and the complete orbital parameters.

In this paper, Doppler radar radial velocity and reflectivity are simultaneously assimilated into a weather research and forecasting (WRF) model by a proper orthogonal‐decomposition‐based ensemble, three‐dimensional variational assimilation method (referred to as PODEn3DVar), which therefore forms the PODEn3DVar‐based radar assimilation system (referred to as WRF‐PODEn3DVar).

Another major advantage is the way the Radial Velocity Method is able to place accurate constraints on a planet’s mass.

In 1995, a team of researchers from the Geneva Observatory, consisting of Michel Mayor and Didier Queloz, discovered the first exoplanet in orbit around a star similar to our Sun. The radial velocity method is one of the principal techniques used in the search for exoplanets.

The Radial Velocity Equation in the Search for Exoplanets ( The Doppler Spectroscopy or Wobble Method ) "Raffiniert ist der Herr Gott, aber Boshaft ist er nicht ( God is clever, but not dishonest - God is subtle, but he is not malicious )", Princeton University’s Fine Hall, carved over the fireplace in the Common Room with relativity equations as motif imprinted into the leaded glass windows

Mostly, a planet is engaged in its certain orbit by the gravitational field of more massive mass/object/star. The radial velocity (RV) method has provided the foundation for the research field of exoplanets. It created the field by discovering the first exoplanets and then blazed a trail by detecting over 1000 exoplanets in orbit around other stars. The method also plays a vital role in transit searches by providing the planetary mass needed to calculate the bulk density of the exoplanet.
