Sentences with phrase «period radial velocity variations»
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).

The radial - velocity variations indicate a highly eccentric orbit with a period of 153.9 days.
Prior to 2009, small but significant variations in radial velocity had been detected which may have been caused by a substellar companion of one to nine Jupiter - masses with an orbital period of 50 years of less (Campbell et al, 1988, pages 904, 906, and 919).
As CORVAL monitoring failed to detect significant radial velocity variations over period of 3,400 days — or over 9.3 years (Duquennoy and Mayor, 1991, pp. 492 and 506), the detection is now considered to be spurious.
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.
