On Lifetimes of Dusty Debris Disks around A-type Stars
(IAU Editorial, 2014-01)
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 ...
Structure and Composition of Two Transitional Circumstellar Disks in Corona Australis
(2010)
The late stages of evolution of the primordial circumstellar disks surrounding young stars are poorly understood, yet vital to constrain theories of planet formation. We consider basic structural models for the disks around ...
Shadows cast by a warp in the HD 142527 protoplanetary disk
(IOP Publisihing, 2015)
Detailed observations of gaps in protoplanetary disks have revealed structures that drive current research on circumstellar disks. One such feature is the two intensity nulls seen along the outer disk of the HD 142527 ...
The Circumstellar Disk and Asymmetric Outflow of the EX Lup Outburst System
(Institute of Physics Publishing, 2018)
We present Atacama Large Millimeter/submillimeter Array (ALMA) observations at 0farcs3 resolution of EX Lup, the prototype of the EXor class of outbursting pre-main-sequence stars. The circumstellar disk of EX Lup is ...
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 ...
