We model the infrared (IR) emission from the double-ring disk of HD 141569A, using a porous dust model that was previously shown to be successful in reproducing the spectral energy distributions (SEDs) of the disks around β Pictoris and HR 4796A. The dust consists of either unaltered or highly processed interstellar materials and vacuum with a volume fraction of ~90%. Together with a population of polycyclic aromatic hydrocarbon (PAH) molecules, of which a large fraction are charged, the porous… 
Modeling the Infrared Emission from the Eridani Disk
We model the infrared (IR) emission from the ringlike dust disk around the main-sequence (MS) star Eridani, a young analog to our solar system, in terms of a porous dust model previously developed
Dust Processing and Grain Growth in Protoplanetary Disks in the Taurus-Auriga Star-Forming Region
Mid-infrared spectra of 65 T Tauri stars (TTS) taken with the Infrared Spectrograph (IRS) on board the Spitzer Space Telescope are modeled using populations of optically thin warm and cool grains to
Resolved Gas Interior to the Dust Rings of the HD 141569 Disk
The disk around HD 141569 is one of a handful of systems whose weak infrared emission is consistent with a debris disk, but still has a significant reservoir of gas. Here we report spatially resolved
Dust and Polycyclic Aromatic Hydrocarbon in the Pre-transitional Disk around HD 169142
The pre-transitional disk around the Herbig Ae star HD 169142 shows a complex structure of possible ongoing planet formation in dust thermal emission from the near infrared (IR) to millimeter
DUST AND POLYCYCLIC AROMATIC HYDROCARBON IN THE HD 34700 DEBRIS DISK
The debris disk around the Vega-type star HD 34700 is detected in dust thermal emission from the near infrared (IR) to millimeter (mm) and submm wavelength range. Also detected is a distinct set of
C2D Spitzer-IRS spectra of disks around T Tauri stars IV Crystalline silicates
Aims. Dust grains in the planet-forming regions around young stars are expected to be heavily processed due to coagulation, fragmentation, and crystallization. This paper focuses on the crystalline
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
A dynamical simulation of the debris disk around HD 141569A
We study the dynamical origin of the structures observed in the scattered-light images of the resolved debris disk around HD 141569A. The disk has two conspicuous spiral rings and two large-scale
PAH chemistry and IR emission from circumstellar disks
Aims. The chemistry of, and infrared (IR) emission from, polycyclic aromatic hydrocarbons (PAHs) in disks around Herbig Ae/Be and T Tauri stars are investigated. PAHs can exist in different charge
An Icy Kuiper-Belt Around the Young Solar-Type Star HD 181327
Context. HD 181327 is a young main sequence F5/F6 V star belonging to the beta Pictoris moving group (age similar to 12 Myr). It harbors an optically thin belt of circumstellar material at radius

Mid-infrared images of the debris disk around HD 141569
We have imaged the circumstellar debris disk around the A0 Ve/B9.5 Ve star HD 141569 (D = 99 pc), at λ = 12.5, 17.9, and 20.8 μm using the Keck II telescope, and confirm the general morphology from
Infrared observations and thermal models of the Beta Pictoris disk
Measurements of the flux from the central portion of the Beta Pic disk performed via photometry at 3.5-20 microns in 4- and 8-arcsec apertures are presented. The 10.1- and 20-micron measurements show

There have been several model analyses of the near- and mid-IR flux from the circumstellar ring around HR 4796A. In one set of models, the 10 and 18 μm IR flux has been attributed to the reprocessing
