Research conducted in the area of stellar cartography being conducted by the OSR has brought to light a phenomenon related to variable stars.

It was always considered an axiom that stellar bodies [for the most part] were immutable, that is to say unchanging in their day to day existence.

But recent observations made during routine cartographic missions have proven this not to be so. Variable stars, have been found in the night sky, ALGOL, Arabic for ‘the ghoul’ [one of the most famous of the eclipsing type], being the second brightest stellar body in the constellation of Perseus; As well as Chi Cygni of the constellation of Cygnus [the Swan].

These, and many other, stellar bodies have demonstrated bewildering traits such as changing their luminosity many times over in periods lasting a few hours to a few days.

Another example of this is Delta Cephei; this stellar body has a 5.4 day period, which is now used to calculate the luminosity of other such stellar phenomenon.

Mira, in the constellation of Cetus, expands and contracts to such an extent that the very shape of Cetus is altered by its undulations.

Such stellar phenomenon is of great interest for the purpose of navigation as well as the purely scientific aspects.

Further research into this phenomenon will be on going.
