A layered edge-on circumstellar disk around HK Tau B
We present the first high angular resolution 1.4 mm and 2.7 mm continuum maps of the T Tauri binary system HK Tau obtained with the Plateau de Bure Interferometer.

Refractory grain processing in circumstellar shells Diagnostic infrared signatures
Recent advances in infrared speckle interferometry reported by Ridgway, et al. (1986) have made possible the determination of the temperatures at the inner radius of certain dusty outflows. When combined with recent data on the thermal annealing and hydrous alteration rates of amorphous magnesium silicate grains, this information allows one to predict ...

Planetesimal formation in turbulent circumstellar disks
Planetesimal formation occurs early in the evolution of a solar system, embedded in the circumstellar gas disk, and it is the crucial first step in planet formation.

The shapes of the circumstellar silicate features [PDF]
Around oxygen-rich stars the spectra of most long-period variables (LPV) show an excess infrared emission which is attributed to circumstellar silicate dust grains.

Detection of C3 in the Circumstellar Shell of IRC+10216
Vibration-rotation lines of C(3) have been identified in the circumstellar spectrum of the obscured carbon star IRC+10216. This molecule is of interest in both the chemistry of flames, where it may be involved in the formation of soot, and in ...

The ultraviolet extinction in M-supergiant circumstellar envelopes [PDF]
Using International Ultraviolet (IUS) archival low-dispersion spectra, ultraviolet spectral extinctions were derived for the circumstellar envelopes of two M supergiants: HD 60414 and HD 213310.

IR emission from circumstellar envelopes of C-rich stars [PDF]
The reliability of a theoretical model that solves the radiative transfer equation in dust clouds surrounding a central star is checked. In particular, it is found that both classical scattering by dust and the back-heating effects are negligible in the ...
