Volatiles in protoplanetary disks [PDF]
, 2014 Volatiles are compounds with low sublimation temperatures, and they make up most of the condensible mass in typical planet-forming environments. They consist of relatively small, often hydrogenated, molecules based on the abundant elements carbon ...

Chemistry in Protoplanetary Disks [PDF]
Chemical Reviews, 2013 This comprehensive review summarizes our current understanding of the evolution of gas, solids and molecular ices in protoplanetary disks. Key findings related to disk physics and chemistry, both observationally and theoretically, are highlighted.

Photoprocesses in protoplanetary disks [PDF]
Faraday Discussions, 2006 Circumstellar disks are exposed to intense ultraviolet radiation from the young star. In the inner disks, the UV radiation can be enhanced by more than seven orders of magnitude compared with the average interstellar field, resulting in a physical and chemical structure that resembles that of a dense photon-dominated region (PDR). This intense UV field

Annual Review of Astronomy and Astrophysics, 2023 Planets form in disks of gas and dust around young stars. The disk molecular reservoirs and their chemical evolution affect all aspects of planet formation, from the coagulation of dust grains into pebbles to the elemental and molecular compositions of the mature planet.

HNC IN PROTOPLANETARY DISKS [PDF]
The Astrophysical Journal, 2015 The distributions and abundances of small organics in protoplanetary disks are potentially powerful probes of disk physics and chemistry. HNC is a common probe of dense interstellar regions and the target of this study. We use the Submillimeter Array (SMA) to observe HNC 3--2 towards the protoplanetary disks around the T Tauri star TW Hya and the ...

MAGNETO-THERMAL DISK WINDS FROM PROTOPLANETARY DISKS [PDF]
The Astrophysical Journal, 2016 ABSTRACT The global evolution and dispersal of protoplanetary disks (PPDs) are governed by disk angular-momentum transport and mass-loss processes. Recent numerical studies suggest that angular-momentum transport in the inner region of PPDs is largely driven by magnetized disk wind, yet the wind mass-loss rate remains unconstrained.

Ionization and heating by X-rays and cosmic rays*
EPJ 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

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