Samenvatting
I review the connection between truncations in stellar disks and warps
in the H I layers in spiral galaxies. The onset of the warps, which are
usually present when there is H I beyond the optical extent is abrupt
and discrete and starts just beyond the truncation. Inside the
truncation disks of galaxies are extremely flat (little deviation from a
single plane). Truncations are difficult to see in galaxies that are not
edge-on. Latest results show that they can be seen also in
inclined/face-on systems at the faintest levels that can be observed,
but only when the galaxy does not have a faint, extended stellar halo.
Much, but not all of what follows has also been covered in the recent
article on Annual Review of Astronomy & Astrophysics by Kruit &
Freeman (2011).
