Protoplanetary disks as a research area encompass the observational, theoretical, and computational study of gas- and dust-rich disks surrounding young stellar objects, which serve as the birthplaces of planets. This field investigates disk structure, composition, thermochemistry, angular momentum transport, and disk evolution through processes such as accretion, turbulence, magnetohydrodynamic effects, dust growth, and planet–disk interactions. Research integrates multiwavelength observations (e.g., ALMA, infrared spectroscopy) with radiative transfer, hydrodynamical, and chemical modeling to constrain disk lifetimes, mass budgets, and conditions for planet formation, as well as to link disk properties to emerging planetary system architectures and demographics.
New research from Rice University suggests that the giant planet Jupiter reshaped the early solar system in dramatic ways, carving out rings and gaps that ultimately explain one of the longest-standing puzzles in planetary ...

In approximately 5 billion years, the sun will deplete its hydrogen fuel and collapse under its own gravity, becoming a white dwarf. Though Earth-sized, this dense remnant will retain much of the sun's gravitational influence.

The Atacama Large Millimeter/submillimeter Array (ALMA) has captured the motion of spirals of dust around a young star and shown that the winding motion of the spiral pattern is conducive to planet formation. This provides ...

Large exoplanets are more easily detected than small ones. It's axiomatic. While large planets block out more starlight during transits, small planets block out much less, letting them hide in the overpowering glare from ...
