Analytical relations for convective core mass, variable-mu structure, and main-sequence end in intermediate-mass stars, with MESA validation.
Roche lobe overflow during gas giant destruction aligns stellar spins with orbits within tens of degrees regardless of starting conditions, offering an observable to differentiate this mechanism from high-eccentricity migration.
2D hydro simulations of a red giant star find that low-frequency mixed modes below 50 microhertz carry the largest kinetic energies, unlike empirical predictions peaking near nu_max, with surface velocities matching in the less-truncated run.
Primordial black holes captured by stars lead to either quiet consumption or explosive disruption via disk formation, producing transients and high-spin remnants with potentially observable event rates.
Hydrodynamical simulations show that high prograde initial stellar spin recovers the dimming trend in rpTDE outbursts, supporting the Hills mechanism for orbit placement.
3D hydro simulations demonstrate that donor central concentration (ρ_c/ρ_bar) controls inspiral morphology and mass-ejection history in common-envelope events for luminous red novae.
Blue straggler stars in old open clusters exhibit a Kraft break in rotation, with rapid rotators above the break and slow rotators below, indicating their envelopes behave like those of single stars.
A coupled MESA-GYRE framework shows interior radiative damping of gravity waves dominates tidal evolution in TOI-5882, predicting a 2-6 fold reduction in engulfment timescale versus equilibrium tide models.
Type Ib supernovae are systematically bluer than Type Ic supernovae in optical colors, likely due to helium-rich versus helium-poor progenitors.
Two long period radio transients are detached white dwarf-M dwarf binaries with matching periods, massive cool crystallized white dwarfs, low inclinations, and an estimated population of 100-2000 such systems within 2 kpc.
Dynamic Time Warping with a shared warping path across parameters aligns binary stellar tracks for accurate interpolation while preserving physical relationships such as the Stefan-Boltzmann law.
GR hydro simulation finds that strongly relativistic TDEs evolve like weakly relativistic ones, with persistent eccentric debris, early but short-lived shocks, and slow circularization driven by stream self-interactions.
A score-based diffusion generative model on deep infrared galaxy photometry yields a star formation rate density peaking at z=1.3 and shows distinct non-parametric star formation histories plus AGN activity peaking during the quenching transition of massive galaxies.
Dynamical tides exciting f-modes during high-eccentricity migration produce the hot Jupiter pile-up, Neptune ridge, and Neptune desert via orbital circularization and selective atmospheric mass loss.
New spectral models of solar-metallicity stellar populations using POSYDON show binary-stripped stars dominating ionizing radiation after about 16 Myr.
A complete classification of Gaia-selected hypervelocity candidates yields 10 D6 and 3 LP 40-365 stars, with forward modeling favoring intermediate-heating evolutionary scenarios and low birth rates relative to the SN Ia rate.
Numerical simulations identify a sharp transition between runaway disruption and stable eccentric mass transfer in star-black hole binaries set by pericenter distance.
Supermassive dark stars powered by dark matter annihilation can collapse into quasi-stars whose envelopes expand and cool to match the observed properties of many JWST Little Red Dots while bypassing the restrictive conditions of nuclear-powered supermassive star formation.
Physics-based annual TSI reconstruction over three millennia yields a maximum difference of 1.04 W/m² in 50-year running means.
Blue straggler stars in old open clusters predominantly appear near the terminal-age main sequence because mass transfer from asymptotic giant branch donors enriches their cores with helium.
A new main-sequence evolution framework implemented in COMPAS yields more massive helium cores, more compact stripped-star radii, and systematically higher black-hole masses than standard prescriptions.
Numerical simulations find that off-center carbon burning in accreting CO white dwarfs produces substantial Si and S abundances that depend on initial carbon content, supporting the double WD merger scenario for SN 2021yfj-like events.
New MESA stellar tracks with varied winds and convective mixing produce a primary black hole mass function with twin peaks near 8 and 13 solar masses in most variations, the higher peak dominated by mass-ratio-reversal systems, with rates varying by a factor of six.
