Roche lobe overflow destruction of hot Jupiters clears all companions from the sub-Jovian desert inside ~4 days while most observed companions remain stable, unlike tidal disruption during high-eccentricity migration.
WD–IMBH tidal disruption disks are advection-dominated, radiate near-Eddington soft X-rays, can emit Galactic MeV neutrinos, and produce decihertz GW bursts.
Dynamical tides exciting f-modes during high-eccentricity migration produce the hot Jupiter pile-up, Neptune ridge, and Neptune desert via orbital circularization and selective atmospheric mass loss.
Numerical simulations identify a sharp transition between runaway disruption and stable eccentric mass transfer in star-black hole binaries set by pericenter distance.
SPH simulations of repeated partial disruptions in 16 WD-BH/NS systems predict three categories of periodically modulated X-ray/GRB transients whose durations and peak rates depend on mass ratio and compactness.
TOI-5882, a lithium-enriched subgiant with a brown dwarf companion, shows enrichment consistent with engulfment of a super-Earth to Neptune-mass planet.
