This work examines the protoplanetary disk of an intriguing young star system HD 34700 A using the Subaru Telescope, verifying the previously discovered disk and spiral structures of the system, and drawing a number of new conclusions on the pitch angle, submicron dust distribution, and the substellar mass objects. Interestingly, previously undetected darkening features on the disk are revealed, the origins of which, however, are not identified in this work. The authors have made a relevant and timely contribution to the field of planet formation, as this work has already accumulated 10 citations since its publication in 2020 according to the NASA ADS. However, a more thorough discussion on the new open questions and potential new research directions generated by this work could have strengthened this work.
