Constraints on the Metallicity-dependent Explodability of Massive Stars from Galactic Chemical Evolution: Toward Alleviating the Red Supergiant Problem

Akihiro Suzuki, Keiichi Maeda, Sojun Ono

Galactic chemical evolution constrains where massive stars form black holes and permits a simplified explodability rule that can ease the red supergiant problem.

Claims

C1strongest claim

The GCE model provides strong constraints on the region of the BH formation in the mass-metallicity space. Guided by these findings, a simplified form of the metallicity-dependent explodability can be constructed to alleviate the RSG problem without violating chemical-evolution observables, if net outflows are negligible/absent and the transition takes place at sub-solar metallicity.

C2weakest assumption

The assumption that net outflows from the galactic system are negligible or absent, which is presented as a necessary condition for the simplified explodability model to remain compatible with GCE constraints (abstract).

C3one line summary

Metallicity-dependent explodability prescriptions for massive stars reproduce observed galactic abundance trends when used in chemical evolution models and permit a simplified form that alleviates the red supergiant problem without violating those trends, provided net outflows are negligible and the
