Every star I ever made was GPMP and PUMP surrounded by HYGN and only lasted a few seconds before lots of OXYG and a little molten BMTL were left.  To solve this problem I'm tryng to make a longer-lasting star using electrons, EXOT that turns into high-energy WARP, and neutrons.

Thought behind using WARP:

Fusion produces neutrons and the high-energy WARP constantly makes makes electrons to merge with the resulting neutrons to make more HYGN; the WARP also makes it's own pressure which eliminates the need for PUMP.  Once the WARP runs out, so does the electrons as fusion does not produce them often enough to keep the fusion sustained.  The pressure would also lower which would stop the fusion all together and the star dies, but it takes a while for the WARP to run out and the star can live for much longer than WARP-free stars.

Strategy:

First I drew a box of ENERGY WALL and inside the center of the box I drew high-temp GPMP surrounded by DMND to protect from the WARP.  The result yielded too much CO2 and most of the CO2 had some trouble making it to the core to fuse, so I tried drawing a box of low-temp GPMP outside the ENERGY WALL to push the gases in; this created a battle between the two forces keeping the star alive; the GPMP-generated negative newtonian gravity fighting to push the gases inward vs. the WARP-generated positive pressure fighting to push the gases outward; this is similar to a real star.  After a while the WARP runs out, the pressure goes down and the gravity wins the battle--though in most (but not all) real life stars this battle ends in a sort of tie.

Problem:

This strategy yielded a more proportional amout of gases and the CO2 had much less trouble fusing but there's a tiny problem; OXYG fuses to molten BMTL with positive newtonian gravity, not negative.  I wanted my stars to last more than a few seconds but it may take hours for a the WARP to run out.  The generation of molten BMTL might reduce the star lifetime to a more acceptable amount; if not, at least it'll make the star more accurate.

Solution:

OXYG fuses with newtonian gravity at 20 or higher; it should also be able to fuse with newtonian gravity at -20 or lower so that people who make WARP-based stars inside cold GPMP containers can have more accurate stars that go though all the steps of fusion.
