The iterated Aluthge Transforms of compact operators

Let $T$ be a bounded linear operator on a Hilbert space. Then the Aluthge transform $\mathrm{\Delta }T$ and the sequence $({\mathrm{\Delta }}^{n}T)$ of Aluthge iterates of $T$ are defined by \begin{align*} ΔT=|T|^{1/2}U|T|^{1/2},,Δ^0T=T,,Δ^nT=Δ(Δ^{n-1}T),,n\in$\mathbb{N}$. \end{align*} We prove that $\mathrm{\Delta }$ is a continuous map on the space of all compact operators on a separable Hilbert space with respect to the norm topology and using this result we also prove that the sequence $({\mathrm{\Delta }}^{n}T)$ converges in the norm topology to a normal compact operator for every compact operator $T$ on a separable Hilbert space. This gives an affirmative answer to two questions raised by Jung, Ko and Pearcy \cite{Pearcy2} for compact operators.
