Ringed Structures of the HD 163296 Protoplanetary Disk Revealed by ALMA.
We present Atacama Large Millimeter and Submillimeter Array observations of the protoplanetary disk around the Herbig Ae star HD 163296 that trace the spatial distribution of millimeter-sized particles and cold molecular gas on spatial scales as small as 25 astronomical units (A.U.). The image of the disk recorded in the 1.3 mm continuum emission reveals three dark concentric rings that indicat...
متن کاملThe Hd 163296 Circumstellar Disk in Scattered Light: Evidence of Time-variable Self-shadowing
We present the first multi-color view of the scattered light disk of the Herbig Ae star HD 163296, based on coronagraphic observations from the Hubble Space Telescope Advanced Camera for Surveys (ACS). Radial profile fits of the surface brightness along the disk’s semi-major axis indicates that the disk is not continuously flared, and extends to ∼540 AU. The disk’s color (V-I)=1.1 at a radial d...
متن کاملDust properties across the CO snowline in the HD 163296 disk from ALMA and VLA observations
Context. To characterize the mechanisms of planet formation it is crucial to investigate the properties and evolution of protoplanetary disks around young stars, where the initial conditions for the growth of planets are set. The high spatial resolution of Atacama Large Millimeter/submillimeter Array (ALMA) and Karl G. Jansky Very Large Array (VLA) observations now allows the study of radial va...
متن کاملCo Gas inside the Protoplanetary Disk Cavity in Hd 142527: Disk Structure from Alma
Inner cavities and annular gaps in circumstellar disks are possible signposts of giant planet formation. The young star HD 142527 hosts a massive protoplanetary disk with a large cavity that extends up to 140 au from the central star, as seen in continuum images at infrared and millimeter wavelengths. Estimates of the survival of gas inside disk cavities are needed to discriminate between clear...
متن کاملMillimeter imaging of HD 163296 : probing the disk structure and kinematics ⋆
We present new multi-wavelength millimeter interferometric observations of the Herbig Ae star HD 163296 obtained with the IRAM/PBI, SMA and VLA arrays both in continuum and in the CO, CO and CO emission lines. Gas and dust properties have been obtained comparing the observations with self-consistent disk models for the dust and CO emission. The circumstellar disk is resolved both in the continu...
