There's been a resurgence of interest in Classic Traveller across the OSR blogosphere of late, with posts from Chaoclypse, friend-of-the-blog VDonut and and a whole... slew (?) of posts from Old Hawkeyes.It feels like a good opportunity to share the expanded system generation procedure I've adapted from a Mongoose Traveller supplement, The Deep Space Exploration Handbook. This expands the variety of systems that can be generated using the rules as presented in Book 3: Worlds and Adventures, primarily through the addition of unusual and anomalous stellar objects. This is also the system I used to initially populate the sector I generated for the Galaxy 24 project.

| PIA23685: What is a Brown Dwarf? https://photojournal.jpl.nasa.gov/catalog/PIA23685 Brown dwarfs are more massive than planets but not quite as massive as stars. Generally speaking, they have between 13 and 80 times the mass of Jupiter. A brown dwarf becomes a star if its core pressure gets high enough to start nuclear fusion |
So – given that a) mechanics aren't subject to copyright and b) this corresponds to non-commercial, fair use of the IP in those books – I hope you can get some mileage out of my interpretation of the system generation procedure, adapted for Classic Traveller.
