A systematic survey catalogs 15,265 super-Nyquist frequencies in 1,309 δ Scuti stars and shows their numbers decrease with stellar evolution, providing a cleaned frequency catalog for asteroseismology.
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.
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.
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.
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.

Mechanisms for magnetic braking boost and disruption: the role of irradiation-driven winds and convective turnover time spike in cataclysmic variables
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.
