Hi Sergey Karavashkin,  You mentioned,
" Dear Colleagues, 
    it is so strange that no one replied. ".

I never saw your post.

I see that you're using Google.

If you want me to see your post,
  you have to make a reply to one of my posts.
  That's probably the only way that I'll ever see it.

Re:  Planet formations from something similar to sun spots,

What about all the supernovae 
  that happen over and over again ?

That results in not only new stars,  but also new planets.
