The other is the regular but minuscule variation in a star's radial velocity — its speed through the galaxy relative to Earth's speed — which indicates that the star is being tugged by an orbiting planet's gravity.
On March 25, 2015, a team of astronomers using the Hubble Space Telescope revealed observations which indicate via the transit method that Alpha Centauri B may have a second planet «c» in a hot inner orbit, just outside planet candidate «b.» After observing Alpha Centauri B in 2013 and 2014 for a total of 40 hours, the team failed to detect any transits involving planet b (previously detected using the radial velocity variations method and recently determined not to be observed edge - on in a transit orbit around Star B).
The primary shows long - period radial velocity variations that indicate the presence of a low mass companion whose projected mass is in the planetary regime (m sin i = 9.33 Mjup).
High - precision radial - velocity measurements confirm a sinusoidal variation with the period and phase predicted by the photometry, and rule out the presence of line - bisector variations that would indicate that the spectroscopic orbit is spurious.
Variations in rotational velocity should indicate regions of varying gravity and therefore mass.
