The paper is in _Nature_ at

but you will need a subscription or pay to read more than the
Abstract. I didn't find a preprint.

The new result implies that many asteroids, especially dark ones,
disintegrate at a few tens solar radii rather than at the much
smaller distances one might expect. Despite the press release, I
don't see anything about what fraction of asteroids disappear this
way versus the fraction destroyed by hitting a planet.

Doesn't it simply mean that any and all asteroids that gets this close
to the Sun, gets destroyed?
