Suggest you do a bit more reading. Mr. Oblivious.

It is great to know about some stars may have a 2nd or perhaps a 3rd chance in life The sky from a planet near the center of the globular cluster may be amazing, however, I don't think even simple lifeforms could ever develop in such a chaotic environment .

Because I'm dying to know the difference between your "Merger" and the "collision or transference" explained by the text. Salacious… please go into detail about your alternative theory.

Crumb Thu, 15 Jan 2009 07:21:19 +0000 http://www.universetoday.com/?p=23607#comment-50026 Another usual adopted alternative theory, other than binary star mass transfer or collision, for the origin of blue stragglers could also be created by the merging close binary stars. This is different from stellar collisions, as it implies stars on independent motions, whose orbits happen to intersect by so-called tidal capture. There are many examples of this theory available in the literature. It is also interesting that many of these blue stragglers are centrally concentrated compared to the evolved stars. This is also not really new, being certainly known for more than a decade or even more. I.e. Guhathakurta, P., "Globular Cluster Photometry with the HST. VII. Color Gradients and Blue Stragglers in the Central Region of M30 from WFP2 Observations."; Astronomical Journal, 116, pg. 1757-1774 (1998) The origin of these "gravitational catastrophe" theory comes from D. Lynden-Bell and Roger Wood in 1968, who in turn, based their important proof on the original work of V.A. Antonov in 1962. Although very complex and mathematically beyond most of us, these works explain much about the evolution of globular cluster (and such stellar system) and the behaviours of stars within them. NOTE: Suggest Frasier Cain might like to consider doing a general podcast on kinetic energy and angular momentum (and its conservation) in action in various forms of astronomical phenomena, which might explain much from issues with star formation to understanding how such stellar mergers might be possible, Another usual adopted alternative theory, other than binary star mass transfer or collision, for the origin of blue stragglers could also be created by the merging close binary stars.
