Hi @lemouth! Thanks for the valuable comment full of nicely explanation which made me learn many things in many ways. The above explanation about neutron star and dark matter interaction is awesome. That's why I too guess the neutron star like Crab pulsar which is old as well still existed.

Moreover, about quark star is a hypothetical type of compact exotic star to which I agree that may be in near future we might observe that as well. :) But I really like the guidance you made it for me to which I am really grateful to you!

Thanks a lot for letting me know one more new thing about dark matter you illustrated above which too will help me out in my future articles!! :)

To be honest there is always something important I learn every time from your articles and comments. Hope to receive your guidance in future as well because I am very passionate about knowing and unfolding the mystery of the space.. Thanks once again!! :)
