Up-to-now known characteristics of radio pulsars , such as mass limits , magnetic field intensity , rotational period , and maximum radiation are mainly of empirical nature .
Applying the Expansive Nondecelerative Universe model ( ENU ) into the issue allows to offer a deeper theoretical explanation of the known parameters and to estimate their limits .
Using the ENU approach the following values related to synchrotron radiation emitting radio pulsars were estimated : the lower and upper limits of magnetic field intensity are B _ { P ( \min ) } \cong 8.5 \times 10 ^ { 6 } T , and B _ { P ( \max ) } \cong 4.4 \times 10 ^ { 9 } T , respectively , the maximum rotation period reaches 3.9 s , the maximum radiation output of a pulsar is P _ { P ( \mathit { rad } , \max ) } \cong 5.6 \times 10 ^ { 29 } W ( all the values relate to radio pulsars with 1.4 solar masses and radius r = 10 ^ { 4 } m and are mass and radius dependent ) .
These values are in accordance with the experimental observations .
