Involving two stars.

The so-called nebula in virgo—a bistellar planetary system in the retrogressive course of envelopment

It must be stabilized about all three principal axes with a fully automatic, offset, bistellar guidance system .

Involving the triangulation of a surface such that each vertex is incident to at most two stars.

Being a particular case of a stellar exchange, a bistellar operation is topology-preserving and Β⁻¹_((σ,τ)) = Β⁻¹_((τ,σ)).

A bistellar graph is defined as a graph whose edge-set can be partitioned into stars so that each vertex is incident to at most two stars.

Having two leaders or headliners.

Brown became overlord of much domestic policy in what Hennessy described as 'a bistellar administration with policy constellations revolving around the two stars'.

Essentially, although each of the "stars" in the bistellar administration was in a strong position of influence, and both essentially agreed on the direction of reform, one of them was anticipating that he would be in an even stronger position in the future.
