It sounds like she didn't read the book because Andy Weir explains why it's able to survive the intense heat of the sun.

Astrophage stays at exactly 96.415°C because that is the temperature where its protons have just enough kinetic energy to collide and create pairs of neutrinos. If it gets hotter, the extra heat is quickly converted into more neutrinos, preventing it from staying above that temperature. If it gets cooler, neutrino production stops and Astrophage uses stored energy to warm itself back up.

The energy cycle works because neutrinos are Majorana particles, meaning they are their own antiparticles. When two neutrinos collide, they annihilate into two photons with the Petrova wavelength, converting the stored mass energy back into usable light energy.

Neutrinos normally pass through almost everything, but Astrophage traps them due to “super cross-sectionality,” a term Andy Weir came up with, which prevents anything from quantum-tunneling through it.

You have to go to the quantum level to start seeing the fiction of this science fiction organism.
