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 کاملDiscovery of a Nearly Edge-on Disk around Hd 32297
We report the discovery of a nearly edge-on disk about the A0 star HD 32297 seen in light scattered by the disk grains revealed in NICMOS PSF-subtracted coronagraphic images. The disk extends to a distance of at least 400 AU (3 .3) along its major axis with a 1.1 mm flux density of 4.81 0.57 mJy beyond a radius of 0 .3 from the coronagraphically occulted star. The fraction of 1.1 mm starlight s...
متن کاملFUSE observations of H 2 around the Herbig AeBe stars HD 100546 and HD 163296
We present the analysis of FUSE observations of two Herbig AeBe stars known to harbor young circumstellar disks: HD 100546 and HD 163296. In both cases we detect absorption lines from warm and dense H2. The thermalization of the rotational levels up to J ∼ 4 allows evaluation of the temperature, density and typical size of the absorbing layer. These quantities are consistent with absorption of ...
متن کاملBorn-again Protoplanetary Disk around Mira B
TheMiraAB system is a nearby ( 107 pc) example of awind accreting binary star system. In this class of system, the wind from amass-losing red giant star (Mira A) is accreted onto a companion (Mira B), as indicated by an accretion shock signature in spectra at ultraviolet and X-ray wavelengths. Using novel imaging techniques, we report the detection of emission at mid-infrared wavelengths betwee...
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...
