  It is known that the finite temperature and density (FTD) corrections
increase the electron mass, charge and modify the properties of the emitted
radiation. All the signals, travelling through the astronomical bodies, carry
over the information of their origin and bring minor details about the
structure and composition of the source. It has been noticed that temperatures
of the early universe add physically measureable mass to electron and large
chemical potential lead to an increase in mass as well. However, the QED
coupling is slowly increased with temperature but is decreased with increasing
chemical potential in superdense systems. Due to the strong relationship
between the properties of electromagnetic signals and composition of the
material of the propagating objects, we propose to incorporate the modified
signal properties to analyze the astronomical data and its interpretation.
Existence of different phases of stellar matter at the quantum scale indicates
frequent phase transitions for rapidly rotating superdense materials. This
information is related to the fact that the allowed range of temperature and
chemical potential for a physical system is determined by the signal properties
and properties changes with the material as well..
