The cover photo illustrates the map of the continuum intensity and the sky maps of the integrated intensity and of the mean value and standard deviation of the Doppler velocity spectra through the study into “The protoplanetary disc HD 163296 as observed by ALMA”.
HD 163296 is one of the few protoplanetary discs displaying rings in the dust component. The present work uses ALMA observations of the 0.9 mm continuum emission, which have significantly better spatial resolution (approximately 8 au) than previously available, to provide new insight into the morphology of the dust disc and its double ring structure.
To get more understanding about the topic, please see the full article “The protoplanetary disc HD 163296 as observed by ALMA” in pages 3-16 of this issue.
