Vortex generation in protoplanetary disks with an embedded giant planet [PDF]

open access: yes, 2007
Vortices in protoplanetary disks can capture solid particles and form planetary cores within shorter timescales than those involved in the standard core-accretion model.

On the Gravitational Instabilities of Protoplanetary Disks [PDF]

open access: yesPublications of the Astronomical Society of the Pacific, 2019
The gravitational instabilities are important to the evolution of the disks and the planet formation in the disks. We calculate the evolution of the disks which form from the collapse of the molecular cloud cores. By changing the properties of the cloud cores and the hydrodynamical viscosity parameters, we explore their effects on the properties of the

Protoplanetary disk lifetimes vs stellar mass and possible implications for giant planet populations

open access: yes, 2015
We study the dependence of protoplanetary disk evolution on stellar mass using a large sample of young stellar objects in nearby young star-forming regions. We update the protoplanetary disk fractions presented in our recent work (paper I of this series)

Molecular Hydrogen Emission from Protoplanetary Disks

open access: yes, 2005
We have modeled self-consistently the density and temperature profiles of gas and dust in protoplanetary disks, taking into account irradiation from a central star.

On the Evolution of Dust Mineralogy, From Protoplanetary Disks to Planetary Systems [PDF]

open access: yes, 2011
Mineralogical studies of silicate features emitted by dust grains in protoplanetary disks and Solar System bodies can shed light on the progress of planet formation.

Modeling and interpretation of images*

open access: yesEPJ Web of Conferences, 2015
Imaging protoplanetary disks is a challenging but rewarding task. It is challenging because of the glare of the central star outshining the weak signal from the disk at shorter wavelengths and because of the limited spatial resolution at longer ...

Substructures in Compact Disks of the Taurus Star-forming Region

open access: yesThe Astrophysical Journal, 2023
Observations of substructure in protoplanetary disks have largely been limited to the brightest and largest disks, excluding the abundant population of compact disks, which are likely sites of planet formation.

Influence of the C/O ratio on titanium and vanadium oxides in protoplanetary disks [PDF]

open access: yes, 2013
Context. The observation of carbon-rich disks have motivated several studies questioning the influence of the C/O ratio on their gas phase composition in order to establish the connection between the metallicity of hot-Jupiters and that of their parent ...
