Model the super-eruptive wind regime beyond hydrostatic MESA-QUEST calculations

Develop a numerical model capable of following the super-eruptive wind regime of the Little Red Dot J1025+1402 (The Egg), which the hydrostatic MESA-QUEST framework is currently unable to handle and for which no converged evolutionary track is obtained.

Background

The Egg has an exceptionally high fitted Eddington ratio, approximately 299, placing it in the super-eruptive regime. The hydrostatic MESA-QUEST calculations fail to produce a converged evolutionary track in this regime, preventing the authors from deriving the same detailed wind properties for The Egg that they derive for the other primary sources.

A successful treatment would need to follow the strongly non-hydrostatic mass loss associated with the most extreme Eddington ratios and would allow the predicted wind velocity, mass-loss rate, and evolutionary state of The Egg to be tested.

References

The Egg has no converged track as it sits in a super-eruptive regime that MESA-QUEST currently is unable to handle, so its row has a velocity estimate only.
