I believe the answer is Corticotrophin releasing hormone. Corticotropin-releasing hormone is a peptide hormone involved in the stress response. It is a releasing hormone that belongs to corticotropin-releasing factor family. Its main function is the stimulation of the pituitary synthesis of ACTH, as part of the HPA axis.  The Corticotropin releasing hormone derived from the placenta is secreted into the maternal circulation in large amounts during the third trimester of human pregnancy and may have an important role in the onset of labor.

The suns density is greatest in which region
Bingel [31]

The sun is most dense at its core.  It forms 10% of the sun's mass.   Because of the enormous amount of gravity compression from all of the layers above it, the core is very hot and dense.

The sun's core is about 16 million K and has a density around 160 times that of water. This is over 20 times denser than the dense metal iron which has a density of 7 times that of water.  However the sun's interior is still gaseous all the way to the very center  because of the extreme temperatures. There is no molten rock like that found in the interior of the earth.
