Tracing the Inner Edge of the Disk around Hd 100546 with Ro-vibrational Co Emission Lines
In this paper we present high resolution 4.7μm spectra of the isolated Herbig Be star HD 100546. HD 100546 has been the subject of intense scrutiny because it is a young nearby star with a transitional disk. We observe the ∆v=1 ro-vibrational CO transitions in order to clarify the distribution of warm gas in the inner disk. Modeling of the CO spectrum indicates that the gas is vibrationally exc...
متن کامل3 A Resolved Circumstellar Disk around the Herbig Ae Star HD 100546 in the Thermal Infrared
We present mid-infrared nulling interferometric and direct imaging observations of the Herbig Ae star HD 100546 obtained with the Magellan I (Baade) 6.5 m telescope. The observations show resolved circumstellar emission at 10.3, 11.7, 12.5, 18.0, and 24.5 μm. Through the nulling observations (10.3, 11.7 and 12.5 μm), we detect a circumstellar disk, with an inclination of 45± 15 degrees with res...
متن کاملASTROPHYSICS ADONIS observations of the HD 100546 circumstellar dust disk ⋆
We report in this letter the first resolved images of the circumstellar dust disk around the Pre-Main-Sequence star HD 100546. These near-infrared images were obtained in J and short K bands with the adap-tive optics system ADONIS at the ESO observatory. A bright disk extending 2 arcsec (200 AU) far from the star and viewed with an inclination with respect to the line of sight around 50 degrees...

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...
