A ~1 solar-mass main-sequence star with supersolar metallicity has been traced back to the galactic center as a hypervelocity star ejected by the Hills mechanism.
Case C mass transfer in binaries with 10-20 solar mass donors naturally produces the dense, nearby CSM required to power interacting supernovae and may account for 13 percent of core-collapse progenitors.
MWC 656 hosts a hot stripped star companion of 1.48 solar masses instead of a black hole.
MIST provides a new publicly available grid of solar-scaled stellar isochrones and evolutionary tracks computed self-consistently with MESA from pre-main sequence through advanced stages for masses 0.1-300 solar masses and metallicities -2 to 0.5.
Direct inclusion of CMFGEN atmosphere grids in STAREVOL evolution calculations lowers effective temperature and radius in the Wolf-Rayet phase to better match observations while leaving internal structure and chemical evolution unchanged.
The iτSBD magnetic braking model attributes the boost K to irradiation-driven winds and the disruption η to a spike in convective turnover time at the fully convective boundary, yielding CV tracks consistent with observations.
3D MHD simulations of CCSN remnants from RSG and WR stars show faster shocks from photoionization and CSM expansion, plus coherent reflected shocks in WR cases, with weakly magnetized bubbles limiting PeV acceleration.
VLBA observations of Orion young stellar binaries yield Keplerian orbits and dynamical masses for four systems, with two showing agreement to SED-based estimates and one confirming an intermediate-mass star with nonthermal emission.
Accretion feedback caps stellar growth rates below 0.1 solar masses per year in AGN disks, eliminates runaway accretion, and produces higher equilibrium masses and luminosities when gap opening is included.
KIC 3868420 is a newly identified high-amplitude δ Scuti-γ Dor hybrid star in the Hertzsprung gap with best-fit mass 2.26-2.30 solar masses, radius 4.41-4.43 solar radii, and age about 540 million years from frequency matching.
Radiative-transfer models of SN2023ixf require prolonged CSM interaction and a cold dense shell to match its multi-wavelength photospheric evolution from 20 to 120 days.
Asteroseismic ages from TESS calibrate [Y/Mg] and [C/N] chemical clocks, revealing a radially dependent [Y/Mg]-age relation that is steeper in the outer Galactic disc and flatter inward, with NLTE corrections and evolutionary stage accounting required for accuracy.
654 WD-FGK binaries cataloged with mostly low-mass hot white dwarfs formed via binary interactions.
A joint convective coupling index shows moderate, age-dependent correlation with rotation periods of solar-mass stars, stronger in younger objects and weaker later.
Rotating stellar models initialized with observed velocity distributions yield modestly lower initial mass estimates for SN II progenitors than non-rotating models, with an upper limit of 20.4 solar masses.
A moderate factor of 2-3 reduction in magnetic braking efficiency at the fully convective boundary suffices to reproduce key features of cataclysmic variable evolution when using an updated saturated prescription.
Nemesis couples global and local astrophysical simulations to match direct N-body results while scaling efficiently when cores exceed the number of planetary systems.
Three new warm Jupiters (periods 11.3–44.4 days, masses 0.51–1.29 M_J, radii ~0.97–0.98 R_J) were confirmed via TESS photometry and follow-up radial velocities and light curves.
Six seismic solar analogs have masses 0.91-1.04 solar masses, radii 0.95-1.08 solar radii, and ages 1.8-9.1 Gyr, with one star matching the Sun closely enough to be called a solar twin.
