Well, the total mass of the asteroid belt is on the order of a small planetary moon (less than 3% of the mass of the Moon). Assuming the Sun even reaches it (which is doubtful) I don't think it will produce significant debris. (And well over half of the mass of the asteroid belt is in just four asteroids.)
what, are comet-tail-like features more massive than an asteroid in our Asteroid belt?
Or a Troyan in Jupiter's orbit? A Coiperian?
And the star does not have to reach its asteroids with its dense co-rotating layers; the star has only to blow off a hydrogen-helium shell or two to scrap each time a little matter from the surface of an asteroid in its orbital positions on the moment each wave was passing the orbit… prove me wrong please
Asteroids are stony. Nothing to blow off, and not enough heat from the star to vaporize rock. And not enough material to produce a detectable amount of material in any case, even if the entire asteroid were vaporized. The tails we see in APODs like this are solar mass structures.
Do I get right?
First there was a core-to-surface shock wave that blew up a surface layer off so it became now the shell and the volume of the nebula.
After the bang there were 10 thousand years of solar wind from the white dwarf so the nebula is kept hot and glowing.
Now at the moment of the bang there were in equatorial belt of the surface of the star some ten thousand super-Jupiter-mass dark spots: electro-magnetic plasma coils; those were solid enough to survive the shock wave. While outside the spots a thin layer got blown off at the speed of 600 km/s, the spots were 10 times more massive for the same area of the shock wave front and, receiving the same momentum, got blown off at the speed of just 60 km/s.
Those coils still travel as whole bodies called knots; while hydrogen shell after 10 thousand years travelled 1.4 ly slowing from 600 km/s to 30 km/s (averaging 42 km/s), the super-Jupiter-knots travelled only half as far averaging just 15 km/s. The stellar wind shadows stretches now all the way from the knots to the shell of the nebula, and the walls of that cones are somehow shining bright.
