Key Words:Hardy space, asymmetric truncated Toeplitz operator, Hankel operator.

Abstract:A necssary and sufficient condition is found for an asymmetric truncated Toeplitz operator with bounded symbol to be compact from one model space to another model space. Also, a shorter proof of the characterization on zero asymmetric truncated Toeplitz operators is presented.
