my fan made system and some info Vulcan is a L type star with the mass of 77.4 Jupiter's Mors is a mercury like world with water vapor atmosphere Janus is a lively world with water, land, plants and even a civilization. Aquillo is a ice world with only a little bit of liquid water. Fortuna is a Neptune like world but warmer.
when life finds way way in a failed stars system Fortuna's orbit may be further then what is shown.
