JWST/MIRI survey of 2-6 Myr Upper Scorpius disks finds diverse chemotypes, 10-1000x lower water luminosities, and evidence that outer dust traps control inner-disk chemistry.
Giant-planet hosts preferentially formed in the metal-rich inner Galaxy and later migrated, while rocky-only systems are less centrally concentrated and show smaller radial excursions.
Hot Jupiter occurrence in the Galactic halo is low at ~0.13% with no significant difference between in-situ and accreted populations, well below disk rates.
Higher host-star C/O ratios correlate with longer orbital periods for giant planets, based on spectra from 598 stars and supported by pebble-formation models.
New data break the eccentricity multimodality of TOI-2134 c to e=0.31±0.01, refine both planets' masses and radii, and yield a 4.7σ RM obliquity of 59±31° for planet c.
Post-processing of 44-year adiabatic 3D simulations of common envelope events yields lightcurves with a 3-5 year hot peak from photosphere expansion, dust formation after 1-3 years causing bolometric decline and 400 K plateau, plus predictions of optical thinning in 100-200 years, matching some obse
TOI-2147 b and TOI-6019 b are confirmed eccentric warm Jupiters with masses of 116 and 149 Earth masses and eccentricities of 0.29 and 0.48.
The Via Project is a planned five-year dual-hemisphere spectroscopic survey targeting over 2 million stars with 100 m/s RV stability and transient spectroscopy to r~24 using instruments on MMT and Magellan/Clay telescopes starting in 2027.
A parametric avoidance model based on stellar age, metallicity, and multiplicity excludes ~50% of 1.74M Gaia DR3 stars as poor candidates for complex life, retaining 777835 targets and releasing the catalog publicly.
A bare-bones cosmological model of artificial infection spread finds that spawn rates above roughly one per million galaxies at 0.1c would infect half the universe by today, tightening constraints on aggressive self-propagating technology.
N-body simulations show that 14 Herculis's orbital architecture requires primordial ejection of an additional massive planet.
GEODES characterizes three accelerating nearby stars, finding a stellar companion, a 45-Jupiter-mass brown dwarf at about 18 AU, and a 9.5-Jupiter-mass companion that is more likely a planet than a brown dwarf.
ML regressors trained on APOGEE DR17 red giants predict C, O, Mg, Si abundances from kinematics and [Fe/H] more accurately than [Fe/H] baseline, with external validation on HARPS FGK dwarfs and reproduction of Galactic chemical evolution trends.
A uniform spectroscopic catalog of 625 exoplanet hosts shows subsolar-metallicity giant-planet hosts are alpha-enhanced relative to both iron-rich hosts and typical metal-poor field stars.
MESA grid models find HD 20794 is a 0.80 solar-mass star aged ~9 Gyr whose observed abundances match core-collapse supernova enrichment and are preserved over Gyr timescales.
Sub-Neptunes around metal-rich stars have a 42.6% conditional probability of cold Jupiters versus 14.5% for super-Earths, showing a metallicity-dependent correlation absent in the latter.
Observational study of 290 exoplanet-host stars finds higher C, O, S, Fe, Ni abundances in giant-planet hosts than small-planet hosts, with C/O ratios, hot/warm differences, and mass correlations that vary by subpopulation.
Barnard's Star planets have masses 0.19-0.84 M_earth, are tidally locked, unlikely to retain primary atmospheres, and possess mantles rich in ferropericlase with less than half Earth's water capacity and radiogenic heating.
Resolves six speculative companions into one giant planet, one eccentric brown dwarf, two low-mass stars, and two stars with no detectable companions.
Tentative evidence for a super-Jupiter at 15-100 AU or brown dwarf at 20-170 AU in 51 Pegasi from RV curvature, but the signal is likely driven by Lick/Hamilton instrument drift.
New homogeneous abundances for 19 elements in 25 JWST planet-host stars show Tcond slopes independent of stellar and planetary properties after GCE correction, indicating mixed origins requiring careful interpretation.
Giant planet multiplicity is low, with 10.6% and 15.8% of Sun-like stars hosting at least one giant planet within 10 au across the two surveys, mostly as singles, inconsistent with scattering models.
SKAO, especially SKA-Mid Band 5, is expected to overcome dust opacity and frequency limits to detect complex prebiotic molecules in high-mass and solar-type protostellar regions.
