New Studies Showing The Solar Systems Location Reletive to the Galactic Plane
November 12th, 2009 by admin
Previously I have sited the journal Nature’s article to show that we are moving away from the galactic plane (3 million years ago) and aren’t due to return for 30 million years give or take. but that article was from 1985.
But thanks to the valiant efforts of these researchers many more studies have been uncovered showing virtually the same thing.
For instance:
Displacement of the Sun from the Galactic Plane Authors: Yogesh C. Joshi (Queen’s University Belfast 2007)
We have carried out a comparative statistical study for the displacement of the Sun from the Galactic plane (Z⊙) following three different methods… We found Z⊙ varies in a range of ~ 13 – 20 pc from the analysis is of YOCs…
or
The Sun’s Displacement from the Galactic Plane from Spectroscopic Parallaxes of 2500 OB Stars Reed, B. Cameron Journal of the Royal Astronomical Society of Canada, Vol. 100, Issue #4, p.146 2006
The Sun’s vertical displacement from the galactic plane, Z_ȯ, is determined model-independently from 3526 spectroscopic parallax distance estimates for 2488 OB stars within 1200 pc of the Sun. The result, 19.6+/-2.1 pc, agrees well with various other recent determinations. The distribution of stellar z-values as a function of galactic longitude shows a very scattered sinusoidal dependence with an amplitude of about 27 pc.
