Query: On one-sided star partial orders on a Rickart *-ring   We compare some recent approaches to extending the notions of left- and
right-star partial order, introduced for complex matrices in early 90-ies, to
bounded linear Hilbert space operators and to certain *-rings, and discuss in
more detail a version of right-star partial order on a Rickart *-ring R.
Regularity of R is not presumed.
