Context. The binary B5V star BD+31?643 exhibits a disk-like structure detected at optical wavelengths. Even though the feature is well centered on the star, it has been argued, based on Spitzer observations, that the feature is a filament not directly associated to the binary star. Aims. The purpose of the present paper is to investigate whether polarization imaging may provide evidence either for or against the disk hypothesis. In addition, we aim at clarifying whether there might be any… Expand
Thermal Pressure in Diffuse H2 Gas Measured by Herschel [C II] Emission and FUSE UV H2 Absorption
UV absorption studies with FUSE have observed H2 molecular gas in translucent and diffuse clouds. Observations of the 158 micron [C II] fine structure line with Herschel also trace the same H2Expand
Polarized radiative transfer equation in some curvilinear coordinate systems
Abstract The differential operator for polarized radiative transfer equation in homogeneous space obeying Euclidean geometry is explicitly written down for several orthogonal curvilinear coordinateExpand


Imaging the circumstellar dust around AGB stars with PolCor
Aims. The aim of this paper is to investigate how the new imaging Polarimeter and Coronograph (PolCor) at the Nordic Optical Telescope** (NOT) can be used in the study of circumstellar structuresExpand
Multicolor Polarimetry of the Dust Disk Candidate BD +31°643
The tentative detection of a dust disk around the main-sequence star BD +31°643 was recently announced by Kalas & Jewitt and represents only the second such object ever to be imaged. Here, we presentExpand
The Spitzer c2d Survey of Large, Nearby, Interstellar Clouds. VI. Perseus Observed with MIPS
We present observations of 10.6 deg^2 of the Perseus molecular cloud at 24, 70, and 160 μm with Spitzer MIPS. The images show prominent, complex extended emission dominated by illuminating B stars onExpand
Widespread Atomic Gas Emission Reveals the Rotation of the β Pictoris Disk
We present high-resolution Na I D spectroscopy of the β Pictoris disk, and the resonantly scattered sodium emission can be traced from less than 30 AU to at least 140 AU from the central star. ThisExpand
Interstellar Gas and Dust in the Young Cluster IC 348
We have completed a multiband absorption- and emission-line study of a star embedded in the young cluster IC 348, to determine the environmental effect of star formation on the interstellar mediumExpand
A Spitzer Census of the IC 348 Nebula
Spitzer mid-infrared surveys enable an accurate census of young stellar objects by sampling large spatial scales, revealing very embedded protostars, and detecting low-luminosity objects. TakingExpand
The Signature of Primordial Grain Growth in the Polarized Light of the AU Microscopii Debris Disk
We have used the Hubble Space Telescope Advanced Camera for Surveys coronagraph to make the first polarization maps of the AU Microscopii debris disk. The polarization rises from 5% at 20 AU to 40%Expand
A candidate dust disk surrounding the binary stellar system BD+31°643
Planetesimals are thought to form within the dense dust disks that surround young stars1, although this process has not been observed directly. In contrast, the presence of dust disks around older,Expand
High-resolution optical and moderate-resolution near-infrared spectra were obtained for 40 near solar mass (~2.0-0.5 M⊙) members of the 2-3 Myr old cluster IC 348 in order to examine establishedExpand
Parameters of Herbig Ae/Be and Vega-type stars ⋆
Context. This work presents the characterization of 27 young early-type stars, most of them in the age range 1‐10 Myr, and three ‐suspected‐ hot companions of post-T Tauri stars belonging to theExpand
