I would propose a working hypothesis that the massive stars are created due to charge unbalance which fragments the MECO.

The Paradox of Youth stars occur in a region where gas clouds cannot theoretically form due to the tidal affects of the massive compact object. It is not physically possible for the stars in question to have migrated to the location, based on the short life times of the massive stars in the clusters and the maximum distance the stars could possible have moved in their lifetimes. There is no other working hypothesis.

Following the logic of the working hypothesis, if the stars in question were formed from MECO fragmentation, they do appear to be very similar to other stars except a significant higher percentage are very large stars. I am looking at observations and observation anomalies associated with galactic evolution, morphology, and mergers to see if I can find observational evidence and logic to support the working hypothesis.

Questions within the logic of the hypothesis, which I am looking for observations evidence to answer. Does the ejection of the charged MECO matter leave a neutral body? i.e. Is the process balanced, in terms of the release and timing of the release of negative and positive charge? The driving mechanism to create the charge unbalance is fast moving in falling plasma that is separated by the MECO's strong magnetic field such that positive ions move to one pole of the MECO and negative charge (electrons) to another. Assuming that the process occurs (i.e. Within the logic of the working hypothesis) there would be a charge unbalance on the surface of the MECO that would be released.

There has that paper that noted that quasar spectrum analysis shows evidence of an increasing long cyclic change in energy spectrum.


Comment:
I also provide a link to the two cusps (rings of stars) paper. The two rings of stars formed farther from the galactic core, 6 million years ago, all stars formed within a period of a million years. (In the region where the two ring of stars formed it is possible for gas clouds to form, however there are no gas clouds there currently.) The authors of the two cusps paper provide a hypothesis that the two rings of stars where created by colliding gas clouds but could not explain, and noted that they could explain, why the stars in question formed all at the same time (approx. 6 million years ago.) within a million years based on stellar analysis.
