Radial velocity measurements of the brown dwarf CD-35 2722 B reveal a strong 169-day periodic signal attributed to a ~0.74 Jupiter-mass satellite, with a weaker secondary signal possibly indicating a second satellite near 2:1 resonance.

Coupled thermal-orbital models show lava planets undergo two-stage migration from ~0.1 AU requiring initial eccentricities >=0.9 and sustained forcing, with migration rate depending on mantle state.
Sustained mass transfer from a circumbinary disc enables giant planet formation in gamma-Cephei-like binaries by prolonging the lifetime of the circumprimary disc against truncation and photoevaporation.
TOI-7154b is a 71.7 M_J brown dwarf in an 8.86-day eccentric orbit around a G star, with eccentricity and age suggesting stellar-like fragmentation origins.
Mars provides a real-world case study of processes like volatile loss, climate evolution, and magnetism that determine habitability on small rocky planets at the edge of habitable conditions.
