  This work presents precise calculations of important electromagnetic
transition amplitudes along with detail of their many-body correlations using
relativistic coupled cluster method. Studies of hyperfine interaction
constants, useful for plasma diagnostic, with this correlation exhaustive
many-body approach are another important area of this work. The calculated
oscillator strengths of allowed transitions, amplitudes of forbidden
transitions and lifetimes are compared with the other theoretical results
wherever available and they show a good agreement. Hyperfine constants of
different isotopes of W VI, presented in this paper will be helpful to get
accurate picture of abundances of this element in different astronomical
bodies.
