Previous analyses of mid-infrared water spectra from young protoplanetary disks observed with the Spitzer-IRS found an anti-correlation between water luminosity and the millimeter dust disk radius observed with ALMA.

On The Degree of Dynamical Packing In The Kepler Multi-planet Systems
Current planet formation theories rely on initially compact orbital configurations undergoing a (possibly extended) phase of giant impacts following the dispersal of the dissipative protoplanetary disk.

JWST Looks Into The Chemical Components Of Exoplanet Formation
Researchers using the James Webb Space Telescope (JWST) have taken a first look at their data that probe the chemistry of the regions of disks around young stars where rocky […]

How Do Rocky Planets Really Form?
A new theory for how rocky planets form could explain the origin of so-called “super-Earths”—a class of exoplanets a few times more massive than the Earth that are the most […]

Different Degrees Of Nitrogen And Carbon Depletion In The Warm Molecular Layers Of Protoplanetary Disks
Observations have revealed that the elemental abundances of carbon and oxygen in the warm molecular layers of some protoplanetary disks are depleted compared to those is the interstellar medium by […]

The Effect of Carbon Grain Destruction On The Chemical Structure of Protoplanetary Disks
The bulk composition of the Earth is dramatically carbon poor compared to that of the interstellar medium, and this phenomenon extends to the asteroid belt. To interpret this carbon deficit […]
