DELOS applies contrastive learning to phase-folded light curves to detect shallow intermediate-to-long period transits, reporting 15.5% and 11.25% gains in combined precision-recall over BLS and TLS in low-SNR tests plus 3-80x speedups.

Close substellar companions suppress metal pollution in white dwarfs by a factor of 5.75 with 87% protection efficiency, backed by observations of 17 systems and N-body simulations.
Reassessment of 12 TTV claims finds only two systems with compelling unique solutions for the perturbing planet, six with multiple viable solutions, and two with weak evidence overall.
Simulations indicate EKL interactions excite TTV phases and disrupt resonances in a significant fraction of near-resonant super-Earth systems over 16 Myr.
Microlensing-inferred free-floating planets plus bound planets require more mass than protoplanetary disks supply, even at 100% conversion efficiency, potentially creating a crisis if the mass function is bottom-heavy.
GTLS delivers a GPU port of TLS that runs a 3000-day light curve in 138 seconds versus 3289 seconds on CPU while producing statistically consistent detection precision (9.3% vs 9.4%) and recall (79.4% vs 81.1%) on synthetic Kepler-like data.
