Interferometry and the study of protoplanetary disks [PDF]

open access: yesEPJ Web of Conferences, 2015
Interferometry offers access to scales that are unresolvable using single dish telescopes, which is especially important when investigating objects with small angular sizes, such as protoplanetary disks. This Chapter introduces the concept of interferometry, and describes the basic aspects of interferometric observations when considering long (i.e. sub-

The Role of Multiplicity in Disk Evolution and Planet Formation [PDF]

open access: yes, 2011
The past decade has seen a revolution in our understanding of protoplanetary disk evolution and planet formation in single star systems. However, the majority of solar-type stars form in binary systems, so the impact of binary companions on ...

Protoplanetary Disk Resonances and Type I Migration [PDF]

open access: yes, 2011
Waves reflected by the inner edge of a protoplanetary disk are shown to significantly modify Type I migration, even allowing the trapping of planets near the inner disk edge for small planets in a range of disk parameters.

A deeply embedded young protoplanetary disk around L1489 IRS observed by the submillimeter array [PDF]

open access: yes, 2007
Circumstellar disks are expected to form early in the process that leads to the formation of a young star, during the collapse of the dense molecular cloud core.

The Determination of Protoplanetary Disk Masses [PDF]

open access: yes, 2017
In this article we review the methods used to determine the gas and dust masses of protoplanetary disks, with an emphasis on the lesser characterized total gas mass. Our review encompasses all the indirect tracers and the methodology that is be used to isolate the hidden H2 via dust, CO, and HD emission.

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.

Ionization and heating by X-rays and cosmic rays*

open access: yesEPJ Web of Conferences, 2015
High-energy radiation from the central T Tauri and protostars plays an important role in shaping protoplanetary disks and influences their evolution. Such radiation, in particular X-rays and extreme-ultraviolet (EUV) radiation, is predominantly generated

Planet Formation in Binary Stars: The case of Gamma Cephei

open access: yes, 2008
Over 30 planetary systems have been discovered to reside in binary stars. For small separations gravitational perturbation of the secondary star has a strong influence on the planet formation process.

Scattered light mapping of protoplanetary disks

open access: yes, 2016
High-contrast scattered light observations have revealed the surface morphology of several dozens of protoplanetary disks at optical and near-infrared wavelengths.
