In 2D GRMHD simulations, magnetised neutron stars hyperaccreting inside massive envelopes can halt accretion above B_surf ~2.3e13 G and launch ~1e46 erg/s precursor jets that still cannot unbind the envelope.
This represents the red super- giant phase, characterised by a large radius and a long lifetime, adopted from our previous study [19]

Hyperaccreting Magnetised Neutron Stars inside Rotating Massive Envelopes: Low-Power Jets and Precursor Flares
In 2D GRMHD simulations, magnetised neutron stars hyperaccreting inside massive envelopes can halt accretion above B_surf ~2.3e13 G and launch ~1e46 erg/s precursor jets that still cannot unbind the envelope.
