Abstract (from CDS):

We study theoretical spectra at mid-infrared (5-40µm) wavelengths of proto-planetary disks surrounding intermediate-mass pre-main-sequence stars. Observations show a wide range of spectral shapes and a rich variety in strength and shape of dust resonances. These strong variations in spectral shape reflect differences in the nature and spatial distribution of dust particles in the disk. The aim of this study is to establish what model parameters influence the mid-IR spectra of planet-forming disks. A grid of models of passively heated proto-planetary disks is used to calculate the infrared spectrum. We use hydrostatic equilibrium disk models and radiative transfer to calculate the emerging spectrum. We focus on the effects that different disk geometries (flaring, self-shadowed) and dust mineralogy have on the emerging 5-40µm spectrum. We adopt four scenarios for the radial and vertical distribution of crystalline silicate dust. In our model, the 23.5µm forsterite band is more sensitive to emission from regions <30AU, while the 33.5µm forsterite band probes regions up to 50AU. The 23.5µm band strength does not depend on the degree of flaring of the disk, while the 33.5 µm band does. Only models with a substantial abundance (>5 percent) of crystalline silicates at a long distance from the star (>20-50AU) show detectable emission in the 33.5µm forsterite band. The carbon-dust abundance affects the strength of the dust resonances in the 10µm spectral region, but not in the 30µm region.

within arcsec The VizieR photometry tool allows for easy visualization of photometry points extracted around the Simbad position from photometry-enabled catalogues in VizieR.
The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding.
Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!).
