We reexamine the role of radiative forces in an orbiting disk. A previous conceptual bias toward radially streaming radiation has caused the potential for strong optically thick line forces in such disks to be overlooked. We discuss possible consequences of including such forces in disk models. Although substantial uncertainty remains because appropriate line opacity distributions have not yet been determined, we conclude that line forces may play a fundamental role in ablation from the disk…

A reconsideration of disk properties in Herbig Ae stars

This paper presents state-of-the-art spectral energy distributions (SEDs) of four Herbig Ae stars, based in part on new data in the mid and far-infrared and at millimeter wavelengths. The SEDs are

A Useful Approximation for Computing the Continuum Polarization of Be Stars

This paper describes a practical model for the polarization of Be stars that can be used to estimate roughly the physical parameters for optically thin circumstellar envelopes from broadband UBVRI

The radiation driven winds of rotating B[e] supergiants

We have formulated the momentum equation for sectorial line driven winds from rotating stars including: (a) the oblateness of the star, (b) gravity darkening (von Zeipel effect), (c) conservation of

Viscous Transonic Decretion in Disks of Be Stars

We study the characteristics of the outflow in disks of Be stars, based on the viscous decretion disk scenario. In this scenario, the matter ejected from the equatorial surface of the star drifts

Hα emission line spectroscopy in NGC 330 - On the hybrid model for global oscillations in Be star circumstellar disks

We perform an observational test on global oscillations in Be star circumstellar disks in the metal deficient environment of the SMC. According to the hybrid model of disk oscillations early-type Be

A natural explanation for periodic X-ray outbursts in Be/X-ray binaries

When applied to Be/X-ray binaries, the viscous decretion disc model, which can successfully account for most properties of Be stars, naturally predicts the truncation of the circumstellar disc. The

Spatially Resolved Circumstellar Structure of Herbig Ae/Be Stars in the Near-Infrared

We have conducted the first systematic study of Herbig Ae/Be stars using the technique of long baseline stellar interferometry in the near-infrared, with the objective of characterizing the

Circumstellar disc of Pictoris: constraints on grain properties from polarization

We model the positional dependence of the optical polarization (BVRI-bands) in the circumstellar disc of Pic- toris as observed by Gledhill et al. (1991) and Wolstencroft et al. (1995). The particles

The magnetic field and wind confinement of beta Cephei: new clues for interpreting the Be phenomenon?

In this paper, we use the very recent spectropolarimetric observations of β Cep collected by Henrichs et al. and propose for this star a consistent model of the large-scale magnetic field and of the

Phase-dependent Spectral Variability in 4U 1907+09

We report on ASCA, RXTE, and archival observations of the high-mass X-ray binary pulsar 4U 1907+09. Spectral measurements of the absorption and flux were made at all phases of the X-ray pulsar orbit,
