Deep MIPS Observations of the IC 348 Nebula: Constraints on the Evolutionary State of Anemic Circumstellar Disks and the Primordial-to-Debris Disk Transition [PDF]

open access: yes, 2008
We describe new, deep MIPS photometry and new high signal-to-noise optical spectroscopy of the 2.5 Myr-old IC 348 Nebula. To probe the properties of the IC 348 disk population, we combine these data with previous optical/infrared photometry and spectroscopy to identify stars with gas accretion, to examine their mid-IR colors,and to model their spectral

One Solution to the Mass Budget Problem for Planet Formation: Optically Thick Disks with Dust Scattering [PDF]

open access: yes, 2019
ALMA surveys have suggested that the dust in Class II disks may not be enough to explain the averaged solid mass in exoplanets, under the assumption that the mm disk continuum emission is optically thin. This optically thin assumption seems to be supported by recent DSHARP observations where the measured optical depths of spatially resolved disks are ...

Incidentally discovered optic nerve head drusen

open access: yesJournal of the Belgian Society of Radiology, 2014
A 34-year-old white woman presented for holocephalic headaches following a blow to the head. She did not mention any vision disturbance. Computed tomography was performed and displayed bilateral calcific deposits in the disk optic areas consistent with ...

Global modeling of radiatively driven accretion of metals from compact debris disks onto the white dwarfs [PDF]

open access: yes, 2011
Recent infrared observations have revealed presence of compact (radii < R_Sun) debris disks around more than a dozen of metal-rich white dwarfs (WD), likely produced by tidal disruption of asteroids. Accretion of high-Z material from these disks may account for the metal contamination of these WDs.

The effect of dissipative corona on the structure and stability of cold optically thick accretion disks at high accretion rates [PDF]

open access: yes, 2002
The vertical structure of optically thick accretion disks is investigated in the two-zone approximation. The disk is divided into an underlying disk and a corona, where the latter is defined as the upper surface layers for which the effective optical depth is unity.

Diagnostics of optic disk drusen in children

open access: yesOftalʹmologiâ, 2016
Diagnosis of deep optic disc drusen (OND) in children is difficult because they are not visualized ophthalmoscopically and often mimic a picture of stagnation, identifying the wrong tactics diagnostic and therapeutic actions.Materials and Methods ...
