The old subgiant 31 Aql exhibits a strong non-cycling magnetic field and revived wind braking torque consistent with a shift to anti-solar differential rotation.

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.
A joint convective coupling index shows moderate, age-dependent correlation with rotation periods of solar-mass stars, stronger in younger objects and weaker later.
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.

MESA Isochrones and Stellar Tracks (MIST). I: Solar-Scaled Models
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.
