The Plaezard Duality

The Plaezard Duality is an extremely strange binary star system located in the Aylothn Galaxy. This system was first identified by Humanity in the 2041, following its creation. Utilizing the prestiged ISS Isvoy, they discovered 2 planets orbiting around both stars. However, the intriguing part is that it consists of an extremely hot O8-class and an extremely old T2-class star with 5 and 6 planets respectively.  No life has been detected around either star. This system is strange because the two stars could not have possibly formed together, due to the vast cosmic timescales needed to produce this T2 brown dwarf, yet the O-type star is only 2 million years old. This means that the brown dwarf was probably captured some time ago, and pulled into a distant orbit. How this capture happened is still unknown.

The Isvoy stuck around to explore however, due to the unusual nature of the system, and scientists found extremely strange and beautiful views on a planet. There, the brown T2-class dwarf is close enough to light up the thick atmosphere (13.1atm) at the same time as the O8-class blue star, which is below the horizon in the opposite direction.  The effect it makes is eerily beautiful.

Also of note is a very green planet in orbit around the O8. Scientists aboard the Isvoy have sampled the atmosphere, and the green color is primarily caused by chlorine gas. No organic chemicals were detected. The planet is far too hot to support life anyhow, at a scorching 672 Centigrade. Surprisingly it held onto its atmosphere, which has a pressure of 1.6atm.

Fortunately, the Isvoy found a temperate O-class moon (2.4) orbiting around the second planet to orbit around both stars, and offloaded an automated survey ship to study both stars and their entourage of planets.
