This document outlines and compares three instability regions for blueward evolving supergiants in the Hertzsprung-Russell (HR) diagram:
1. Areas where stars are dynamically unstable based on the criterion that the first generalized adiabatic exponent G1 is less than 4/3.
2. Areas where the effective acceleration in the upper part of the photospheres is negative, directed outward.
3. Areas where the sonic points of the stellar winds are situated inside the photospheres deeper than an optical depth of 0.01.
The document compares the results to the positions of actual stars in the HR diagram and finds evidence that recent strong contraction of the yellow hypergiant
