Abstract: While the properties of axions have been studied primarily through high-energy physics and cosmology, there are some potential connections between the research results and the aerospace field. We study the properties of axions in hot and dense matter with three different sets of parameters in the Nambu-Jona-Lasinio model, including axion mass and self-coupling. We discussed axion mass and self-coupling, noting that axion properties are very sensitive to chiral phase transitions for three sets of parameters. The axion mass and self-coupling rapidly decrease in the chiral crossover region. The value of self-coupling becomes very sharp, appearing as a kinklike feature in the chiral phase transition.
