Abstract
The high-temperature expansion for closed superstring one-loop free en ergy is studied. The Laurent series representation is obtained and its sum is analytically continued in order to investigate the nature of t he critical (Hagedorn) temperature. It is found that beyond this criti cal temperature the statistical sum contribution of the free energy is finite but has an imaginary part, signalling a possible metastability of the system.
