The paper is concerned with the identification of the key mechanisms controlling deflagration-to-detonation transition in a stellar medium. The issue of thermal runaway triggered by positive feedback between the advancing flame and the flame-driven precompression is discussed in the framework of a one-dimensional flame-folding model. The paper is an extension of the authors’ previous study dealing with the non-stoichiometric fusion, (Formula presented.), kinetics (Phys.Rev.E, 103(2021)) over physically more relevant, (Formula presented.), kinetics. Despite this change the runaway effect endures. The mean velocity (Formula presented.) of the pretransition flame does not reach the threshold of Chapman–Jouguet deflagration.
