Sentences with phrase «small velocity variations»

In 1988, Campbell et al also reported finding small velocity variations that could be the result of a substellar object of one to nine times the mass of Jupiter that may orbit Xi Boötis B.

Not exact matches

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).

Kepler - 19 joins the small number of systems that reconcile transit timing variation and radial velocity measurements.

If you are new to this saga make sure you read Tau II Abstract: The successful detection is reported of radial - velocity variations due to orbital motion of the substellar companion of the star tau Boötis, from data obtained with a small aperture (0.4 - m) telescope and a fibre - fed high resolution spectrograph.

The detected velocity variations were too small to be cause by a body orbiting star A, which is more massive (see HR 5544 on page 919).
