re: A planet in the globular cluster M4 Maybe NOT
Unlikely, but bear with me here.
We do not know that perhaps this "planet" could have been formed from the debris of the neutron star formation. The partner (now a white dwarf) possibly coulda captured mass ejected from the neutron star. Far, far more than a few Jupiters mass gets ejected when stars die, even from low mass stars like the sun.
