Koyama
Geography
Koyama is a stable, main-sequence G-type yellow dwarf covered in convection cells - granules of rising and falling plasma - that give its surface a honeycomb-like appearance. Koyama burns hydrogen steadily that creates a long-term luminosity. Its corona frequently erupts with flares and coronal mass ejections that arc across tens of thousands of kilometers.
Localized Phenomena
Radio Signal
Its magnetic field is strong and so expansive that it sweeps through the ionized gas surrounding the stars and regularly distorts the shape of the debris that drift between the two. The interaction between its magnetic fields, orbital debris and its orbital path with Aditya produces constant synchrotron radiation. Like its companion, Koyama’s magnetosphere acts as both producer and amplifier of the background hum that permeates the whole system.Natural Resources
