Direct imaging reveals enhanced metallicity and aligned orbit in 29 Cyg b, supporting protoplanetary disk formation near the deuterium burning limit.
First obliquity measurement in an M dwarf binary shows alignment, with tentative evidence that aligned orbits around cool stars and wide separations also hold for brown dwarfs and binaries.
Discovery and spectro-photodynamical characterization of TIC 295741342, a coplanar triply-eclipsing triple with a giant tertiary showing two degenerate evolutionary states and predicted Roche lobe overflow.
Atmospheric retrievals yield C/O = 0.57±0.01, [M/H] = 0.18±0.05, and 12CO/13CO ≈ 95 for 2MASS J0249-0557 c, matching benchmark brown dwarfs and favoring star-like gravitational collapse over disk accretion.
Stronger radiation environments produce more massive, hotter protostellar discs whose fragments are large and disruptive rather than planetary-mass.
The disk instability model remains viable for explaining giant planets that form early, at large orbital distances, and around M-dwarf stars, supported by updated simulations and observations.
