A model for irradiated dust disks around Herbig Ae stars is proposed. The model is based on the flaring disk model given by Chiang and Goldreich in 1997, but with the central regions of the disk removed. The inner rim of the disk is puffed up and is much hotter than the rest of the disk because it is directly exposed to the stellar flux. If located at the dust evaporation radius, its reemitted flux produces a conspicuous bump in the spectral energy distribution (SED) that peaks at 2-3 μm. We… 

PAHs in circumstellar disks around Herbig Ae/Be stars

We investigate the presence and properties of PAHs on the surface of circumstellar disks around Herbig Ae/Be stars by comparing the predictions of disk models with observations. We present results of

Large dust grains in the inner region of circumstellar disks

Context. Simple geometrical ring models account well for near-infrared interferometric observations of dusty disks surrounding pre-main sequence stars of intermediate mass. Such models demonstrate

The complex structure of the disk around HD 100546 - The inner few astronomical units

Disclosing the structure of disks surrounding Herbig AeBe stars is important to expand our understanding of the formation and early evolution of stars and planets. We aim at revealing the sub-AU disk

Constraints on the height of the inner disk rim in pre-main-sequence stars

The structure of inner region of protoplanetary disks around young pre-main-sequence stars is still poorly understood. This part of the disk is shaped by various forces that influence dust and gas

In this paper the two-dimensional structure of protoplanetary disks around Herbig Ae/Be stars is studied. This is done by constructing a self-consistent model based on 2-D radiative transfer coupled

Dust Disks Around Young Stellar Objects

To reproduce the spectral energy distributions (SEDs) of young stellar objects (YSOs), we perform radiative transfer model calculations for the circumstellar dust disks with various shapes and many

Dust in the disk winds from young stars as a source of the circumstellar extinction

We consider the problem of dust grain survival in the disk winds from T Tauri and Herbig Ae stars. For our analysis, we have chosen a disk wind model in which the gas component of the wind is heated

Near-Infrared and the Inner Regions of Protoplanetary Disks

We examine the "puffed-up inner disk" model proposed by Dullemond, Dominik, & Natta for explaining the near-IR excess radiation from Herbig Ae/Be stars. Detailed model computations show that the

Shadows, gaps, and ring-like structures in protoplanetary disks

We study the structure of passively heated disks around T Tauri and Herbig Ae stars, and present a vectorized Monte Carlo dust radiative transfer model of protoplanetary disks. The vectorization

Explaining UX Orionis Star Variability with Self-shadowed Disks

In this Letter we propose a new view on the phenomenon of Algol-type minima in the light curves of UX Orionis stars (UXORs). The idea is based on the earlier proposal by various authors that UXORs



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

Accretion Disks around Young Objects. II. Tests of Well-mixed Models with ISM Dust

We construct detailed vertical structure models of irradiated accretion disks around T Tauri stars with interstellar medium dust uniformly mixed with gas. The dependence of the structure and emission

Accretion Disks around Young Objects. I. The Detailed Vertical Structure

We discuss the properties of an accretion disk around a star with parameters typical of classical T Tauri stars (CTTSs) and with the average accretion rate for these disks. The disk is assumed steady

Spectral Energy Distributions of Passive T Tauri Disks: Inclination

We compute spectral energy distributions (SEDs) for passive T Tauri disks viewed at arbitrary inclinations. Semianalytic models of disks in radiative and hydrostatic equilibrium are employed. Over

A Survey for Circumstellar Disks around Young Stellar Objects

Results are presented from a survey for 1.3 mm radiation toward 86 stars in the Taurus-Auriga dark clouds, including classical T Tauri stars, stars in T associations, and a few weak emission-line

The excess infrared emission of Herbig Ae/Be stars - Disks or envelopes?

We suggest that the near-infrared emission of many Herbig Ae/Be stars arises in surrounding dusty envelopes, rather than circumstellar disks. Hillenbrand et al. and Lada & Adams showed that

The temperature profile of T Tauri disks

This paper proposes that T Tauri stars are three-component systems, formed by a star, its circumstellar disk and a tenuous, dusty envelope which surrounds both. The dust in the envelope scatters and

A High-Resolution Study of Gas and Dust around Young Intermediate-Mass Stars: Evidence for Circumstellar Disks in Herbig Ae Systems

As part of a long-term program of observations to search for and characterize disks of gas and dust around intermediate-mass counterparts to solar-mass T Tauri stars, we have probed the environments

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

ISO spectroscopy of circumstellar dust in 14 Herbig Ae/Be systems: Towards an understanding of dust processing

We present Infrared Space Observatory (ISO) spectra of fourteen isolated Herbig Ae/Be (HAEBE) stars, to study the characteristics of their circumstellar dust. These spectra show large star-to-star
