3b. Interacting Triples which are Aligned
Surprisingly, a large number of interacting triple systems show a
tendency towards alignment, the statistical and physical significance
of which has yet to be determined. In this sub-category are shown some
interacting triple systems illustrating various degrees of alignment.
Many of the galaxies in chains, Category 17,
show disturbance, so the
present sub-category is related to that Category as well. It is also
true that many apparent companions tend to be diametrically aligned
across central galaxies so that the present Category is also related
to Category 8, and to
Categories 4 and 5.
