Morphology of the very inclined debris disk around HD 32297⋆
Context. Direct imaging of circumstellar disks at high angular resolution is mandatory to provide morphological information that constrains their properties, in particular the spatial distribution of dust. For a long time, this challenging objective was, in most cases, only within the realm of space telescopes from the visible to the infrared. New techniques combining observing strategy and dat...
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 کاملThe twofold debris disk around HD 113766 A⋆
Context. Warm debris disks are a sub-sample of the large population of debris disks, and display excess emission in the mid-infrared. Around solar-type stars, very few objects (∼2% of all debris disks) show emission features in mid-IR spectroscopic observations that are attributed to small, warm silicate dust grains. The origin of this warm dust could be explained either by a recent catastrophi...
متن کاملA Ring of Warm Dust in the Hd 32297 Debris Disk
We report the detection of a ring of warm dust in the edge-on disk surrounding HD 32297 with the GeminiN/MICHELLE mid-infrared imager. Our N-band image shows elongated structure consistent with the orientation of the scattered-light disk. The Fν(11.2μm) = 49.9±2.1 mJy flux is significantly above the 28.2±0.6 mJy photosphere. Subtraction of the stellar point spread function reveals a bilobed str...
متن کاملCarma Millimeter-wave Aperture Synthesis Imaging of the Hd 32297 Debris Disk
We present the first detection and mapping of the HD 32297 debris disk at 1.3 mm with the Combined Array for Research in Millimeter-wave Astronomy (CARMA). With a subarcsecond beam, this detection represents the highest angular resolution (sub)mm debris disk observation made to date. Our model fits to the spectral energy distribution from the CARMA flux and new Spitzer MIPS photometry support t...
