Proxima Centauri: a transitional modified Newtonian dynamics controlled orbital candidate?
The triple-system candidacy of Proxima Centauri with α Centauri A/B is reviewed in terms of its potential to demonstrate an orbit controlled according to modified Newtonian dynamics (MOND). It is noted that Proxima is already sufficiently distant from α Cen A/B that MOND corrections to its speed and...

Summary: | The triple-system candidacy of Proxima Centauri with α Centauri A/B is reviewed in terms of its potential to demonstrate an orbit controlled according to modified Newtonian dynamics (MOND). It is noted that Proxima is already sufficiently distant from α Cen A/B that MOND corrections to its speed and orbit should be present and therefore potentially measurable. It is argued that present-day observations of the Proxima–α Centauri A/B system do not rule out the possibility that Proxima occupies a low-eccentricity orbit with an orbital period of the order of a few million years. |
