Temperature and time generating the observed anti-correlations ¹²C–¹⁴N (upper-left), ¹⁶O–²³Na (upper-right), ²⁴Mg–²⁷Al (middle-left), and ²⁴Mg–³⁹K (middle-right). The lower middle and right panels represent the intersection of the parameter space reproducing the observed abundance patterns in light elements (middle) and in all the elements studied (right). Only a small region in temperature and time makes it possible to reproduce the light element patterns. At such temperature and time, ³⁹K can not be enhanced, so a second set of temperature and time values are needed.
