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.
Planets may actually form more easily around double stars than around single stars like our sun, according to new research from astrophysicists at the University of Lancashire. Binary stars are common in our galaxy, yet for ...

Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain its formation that way.

Planetary scientists have long debated where the material that formed Earth comes from. Despite its location in the inner solar system, they consider it likely that 6–40% of this material must have come from the outer solar ...
