The Disk Gas Mass and the Far-IR Revolution
Edwin A. Bergin, Klaus M. Pontoppidan, Charles M. Bradford +13
The gaseous mass of protoplanetary disks is a fundamental quantity in planet formation. The presence of gas is necessary to assemble planetesimals, it determines timescales of gian…
Ionization-Driven Depletion and Redistribution of CO in Protoplanetary Disks
Sarah E. Dodson-Robinson, Neal J. Evans, Alyssa Ramos +2
Based on the interstellar CO/H2 ratio, carbon monoxide-based censuses of protoplanetary disks in Lupus, sigma Orionis, and Chamaeleon I found no disks more massive than the minimum…
The Effects of Protostellar Disk Turbulence on CO Emission Lines: A Comparison Study of Disks with Constant CO Abundance vs. Chemically Evolving Disks
Mo Yu, Neal J. Evans, Sarah E. Dodson-Robinson +2
Turbulence is the leading candidate for angular momentum transport in protoplanetary disks and therefore influences disk lifetimes and planet formation timescales. However, the tur…
The abundance and thermal history of water ice in the disk surrounding HD142527 from the DIGIT Herschel Key Program
M. Min, J. Bouwman, C. Dominik +9
The presence or absence of ice in protoplanetary disks is of great importance for the formation of planets. By enhancing the solid surface density and increasing the sticking effic…
