Multiwavelength optical properties of compact dust aggregates in protoplanetary disks
(EDP SCIENCES, 2016)
Context. In protoplanetary disks micron-size dust grains coagulate to form larger structures with complex shapes and compositions. The coagulation process changes the absorption and scattering properties of particles in ...
Variability and dust filtration in the transition disk J160421.7-213028 observed in optical scattered light
(EDP Sciences, 2015)
Context. Protoplanetary disks around young stars are the birth-sites of planets. Spectral energy distributions and direct images of a subset of disks known as transition disks reveal dust-depleted inner cavities. Some of ...
The nature of transition circumstellar disks. III. Perseus, Taurus, and Auriga
(IOP Publishing, 2012-05)
As part of an ongoing program aiming to characterize a large number of Spitzer-selected transition disks (disks with reduced levels of near-IR and/or mid-IR excess emission), we have obtained (sub)millimeter wavelength ...
Evolutionary stages and disk properties of young stellar objects in the Perseus cloud
(NATL ASTRONOMICAL OBSERVATORIES, CHIN ACAD SCIENCES, 2015)
We investigated the evolutionary stages and disk properties of 211 young stellar objects (YSOs) across the Perseus cloud by modeling their broadband optical to mid-infrared (IR) spectral energy distribution (SED). Our ...
STRATUS optical coherence tomography in unilateral colobomatous excavation of the optic disc and secondary retinoschisis
(Springer, 2005-01-01)
Purpose: To report the STRATUS optical coherence tomography (STRATUSOCT) findings in a patient with unilateral coloboma- like excavation of the optic disc without pit but secondary retinoschisis, as well as to discuss the ...
BINARIES AMONG DEBRIS DISK STARS
(2012-02-01)
We have gathered a sample of 112 main-sequence starswith known debris disks.We collected published information
and performed adaptive optics observations at Lick Observatory to determine if these debris disks are ...
Different presentations of intraretinal fluid collections in optic disc pits: OCT study of 3 cases
(Conselho Brasileiro de Oftalmologia, 2006-10-01)
The congenital optic disc pit is a rare anomaly that can lead to major visual impairment associated with subretinal fluid accumulation. The authors describe the optical coherence tomography study of three cases of untreated ...
Near infrared polarimetry of a sample of YSOs
(EDP SCIENCES S A, 2009)
Aims. Our goal is to study the physical properties of the circumstellar environment of young stellar objetcs (YSOs). In particular, the determination of the scattering mechanism can help us to constrain the optical depth ...
The Optical Gravitational Lensing Experiment. OGLE-III Photometric Maps of the Galactic Disk Fields
(2010)
We present OGLE-III Photometric Maps of the Galactic disk fields observed during the OGLE-III campaigns for low luminosity transiting objects that led to the discovery of the first transiting exoplanets. The maps contain ...
