Infernum (natively Valotolave, lit. "burning land") is a hot jupiter planet orbiting close to Solakku. It orbits with a short period of about 25 hours, making it observable as transiting Solakku several times per Avalon day. Its close proximity to Solakku is responsible for tidal effects on the surface of the star, which trigger observable stellar activity.
Physical Characteristics
Composition
The upper atmosphere for Infernum is observed to contain 96% Hydrogen, with almost 4% Helium and traces of various molecules such as titanium monoxide and carbon monoxide. However, the overall ratio of gases within the planet is estimated to be closer to 80% Hydrogen and 20% Helium. A significant amount of silicates and iron are observable in Infernum’s spectrum, dredged up by the high temperatures.
Size and mass
Infernum measures about 16 Earth radii, or 50 times the size of Avalon. However, this figure is only a rough average. In reality, Infernum is prolate as it is being stretched by the gravity of Solakku. Its radius is additionally being inflated by the high temperatures puffing it up even before being stretched.
Infernum’s mass sits at 985 Earths or 36,000 Avalons, making it the heaviest planet in the Solakku system, only eclipsed by the star Crest. This mass is still by far not enough to have it be considered a brown dwarf, despite the fact that Infernum visibly radiates light on its far side. This mass is also slowly dropping as Infernum undergoes mass loss from Solakku’s gravity slowly stripping material from Infernum’s atmosphere. The high temperatures also aid in allowing atoms to be accelerated away from the planet. However, this process is very slow and is expected to take much longer to completely strip the planet of its atmosphere than it will take for its orbit to drop past the roche limit.
Atmosphere
Infernum’s atmosphere consist primarily of hydrogen and helium, with smaller amounts of other compounds such as iron, titanium monoxide, carbon monoxide and even water and ammonia vapors.
A thick cloud layer of silicate and iron vapors is constantly maintained everywhere on the planet. As these are highly opaque, they make direct observation of deeper layers of the planet difficult. They are also highly reflective, raising Infernum’s albedo to 0.5. It is assumed that, just like clouds on other planets, these are capable of precipitation, in this case in the form of droplets of molten iron, which re-evaporate in the hotter deeper layers of the planet.
The atmosphere of Infernum is also characterized by intense winds circulating heat between the near and far side at speeds of up to 12 km/s. The temperature of the day side is about 3,187 K (2,910 °C; 5,280 °F), which drops to 1,853 K (1,580 °C; 2,880 °F) on the night side. The day side temperature is actually high enough to ionize hydrogen. These hydrogen ions flow to the far side and recombine into neutral atoms, before cycling back towards the near side.
