Circumbinary -- around both components of a binary. The eclipse timing method relies on variations in the time between eclipses in an eclipsing binary due to the motions of the stars induced by orbiting planets. To find out exactly I suggest you read the paper I linked to previously.

So how is it that i can isolate n in this equation?
Take logarithms.

The HW Virginis system may reveal more about the evolution of planets around stars similar to the Sun as they go through their red giant phase. HW Virginis B, now a red dwarf of mass 0.142, may have originally been a warm brown dwarf that accreted mass from HW Virginis A and spiralled in under the drag of the red giant's extended envelope.
