abstract
When we are fortunate enough to view an exoplanetary system nearly edge-on, the star and planet periodically eclipse each other. Observations of eclipses (transits and occultations) provide a bonanza of information that cannot be obtained from radial-velocity data alone, such as the relative dimensions of the planet and its host star, as well as the orientation of the planet's orbit relative to the sky plane and relative to the stellar rotation axis. The wavelength-dependence of the eclipse signal gives clues about the the temperature and composition of the planetary atmosphere. Anomalies in the timing or other properties of the eclipses may betray the presence of additional planets or moons. Searching for eclipses is also a productive means of discovering new planets. This chapter reviews the basic geometry and physics of eclipses, and summarizes the knowledge that has been gained through eclipse observations, as well as the information that might be gained in the future.

Tentative CO detection from WASP-33b eclipse data alone with SPIRou validates stacking ingresses/egresses and shows Doppler eclipse mapping can constrain rotation with additional observations.
New MAROON-X observations of HAT-P-70b detect multiple neutral and ionized metals with day-to-night wind signatures and demonstrate that ionization-aware retrievals yield abundance ratios closer to solar values except for enhanced nickel.
New 2025 transit timing for HIP 41378 f confirms large TTVs and is combined with prior data on planets d and e in an N-body model to update ephemerides and predict future transits.
MA-DHRL-OM decomposes overlay multicast routing into hierarchical stages with multi-agent RL to improve delay, bandwidth use, and stability over prior methods.
TOI-4311 hosts a 0.99-day super-Earth (1.38 R_earth, 4.5 M_earth) and 15-day sub-Neptune (2.47 R_earth), plus a candidate 38-day planet, with the dense inner planet potentially challenging formation theories given the host's galactic population.
Differentiable optical simulation models telescope jitter blurring and shows that two-dimensional jitter models avoid systematic bias in binary separation measurements for the TOLIMAN exoplanet mission.
TOI-1710 b has a true obliquity of 149 degrees indicating retrograde motion, favoring high-eccentricity migration via planet-planet scattering and Kozai-Lidov cycles for this tidally detached super-Neptune.
TOI-1533 hosts an inner sub-Neptune (P=3.63 d, R=3.15 R⊕) and outer super-Neptune-mass hot giant (P=8.06 d, R>7.5 R⊕, M≈40 M⊕, ρ<0.48 g cm⁻³) both transiting an active K-dwarf.
Revised mass of 0.503 M_Earth and radius of 0.736 R_Earth for GJ 367 b give a density of 6.9 g cm^{-3} and an iron fraction of 50-70% via new tidal and composition modeling.
Lazuli is proposed as a space observatory combining flagship sensitivity with response times one to two orders of magnitude faster than current large facilities to enable new time-domain and multi-messenger science.
Mass of 13.7 Earth masses and density 0.4 g cm^{-3} measured for TOI-1883 b, a super-Neptune in the ridge regime around an early-M dwarf, with implications for disk migration and photoevaporation.
AstroSkyFlow generates simulated time-series astronomical images with realistic noise and variability, outperforming SkyMaker in noise and PSF reproduction while recovering injected signals such as exoplanet transits and asteroid trails.
Re-analysis of multi-year RV data and TESS photometry detects Gliese 48 b, a temperate super-Earth with P=39.63 days, M sin i=8.11 Earth masses, no transit, and incident flux 0.889 S_earth.
TOI-159 b is confirmed as the hottest known eccentric hot Jupiter (e = 0.24) with a 13-sigma Keplerian detection around a young gamma Doradus star, including a preliminary low-resolution transmission spectrum.
Simulations predict very limited transiting exoplanet confirmations from LSST due to observing cadence constraints, with only a few possible in DDF for hot planets on M dwarfs.
