Planets with realistic dense cores survive close star encounters without total disruption, allowing more to circularize into hot Jupiters or be ejected after mass loss.
ZLK oscillations in Sgr A* triples enhance dual-line GW source formation rates by a factor of 5-10.
Scattering between close-in super-Earths and secularly perturbed cold planets can launch some planets into free-floating orbits.
Three accelerating stars yield one stellar companion at 166 AU, one 45 Jupiter-mass object at ~18 AU, and one 9.5 Jupiter-mass object at 6.4 AU that is 65% likely to be a planet.
N-body simulations demonstrate that post-capture chaotic planet-planet interactions around pulsars can produce stable low-eccentricity orbits after ejections.
LILA can detect IMBH binaries at redshifts 20-30, IMRIs, and provide months-to-years early warnings with high-SNR events for gravity tests.
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.
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.
Mock catalogs of Milky Way white dwarf mergers are created with COSMIC and released publicly, summarizing outcomes by mass and composition while varying binary evolution uncertainties to connect with LISA sources.
TESS asteroseismology of red giants in NGC 188 and NGC 6791 recovers masses around 1.1 solar masses, an RGB mass loss of 0.02 solar masses, and a 7 Gyr cluster age consistent with prior estimates.
A synthesis of observational data on red novae as stellar merger events, including outburst properties, progenitor diversity, and long-term remnants.
