Hybrid hydro/direct N-body simulations of dense high-redshift gas clouds form very massive stars via runaway collisions that collapse to IMBHs capable of growing from ~6700 to ~62000 solar masses in 100 Myr under optimistic assumptions.
Physics-based annual TSI reconstruction over three millennia yields a maximum difference of 1.04 W/m² in 50-year running means.
FUor masses inferred from Keplerian line broadening in H-band spectra match the solar neighborhood IMF, indicating a universal eruptive phase during star formation.
DSEE is a flow-based emulator that generates stellar evolution tracks and isochrones as probabilistic outputs from a single model trained on millions of simulations, enabling fast interpolation and uncertainty-aware analyses.
In low-extinction galactic open clusters fast and slow rotators populate distinct parts of the extended main-sequence turnoff while differential extinction inflates the turnoff width and biases age estimates in others.
Spectral synthesis confirms β PsA is nearly pole-on (i≈4.75°) with rapid rotation (Ω/Ωcrit≈0.93), gravity darkening, and true luminosity 26.2 L⊙.
New high-resolution spectra yield abundances for 7 neutron-capture elements in open cluster stars, revealing flat Milky Way gradients for second-peak s- and r-process species and shallower slopes for first-peak s-process.
Semi-analytical models show AGN disks produce repeated BBH mergers with a high-mass tail beyond the pair-instability gap, more efficiently at low viscosity, with spin and mass-ratio signatures that can match events like GW190521.
Validation of a 135 Myr, 3.6 R_E transiting planet with aligned obliquity and TTV evidence for a near-resonant companion.
Combined JWST spectra of Y dwarf WD 0806-661B fitted with ATMO 2020++ models give Teff 357 K, radius 1.08 RJup and mass 7 MJup, consistent with evolutionary models at 1.6 Gyr.
Weak-CN features in red supergiants across the LMC, M33, and M31 are the expected molecular-equilibrium signature of ordinary cool RSGs rather than an exotic carbon-star intermediate.
GaiaNIR retains sensitivity to extended dark matter halos in globular clusters under strong extinction while Gaia degrades, enabling studies in obscured regions.
New companion HIP 53005 C shows strongly conflicting mass estimates of ~80 M_Jup from photometry versus ~185 M_Jup from dynamics, possibly indicating binarity or an unseen closer companion.
Theoretical predictions for local BBH merger rates exceed observations by a factor >10 under conservative SFRD and metallicity assumptions, indicating need for revisions in stellar evolution.
