MSFA-Net applies multi-scale convolutions and soft frequency attention to LAMOST spectra, achieving high-precision BHB identification and adding 3583 new candidates to the catalog.
Binary population synthesis predicts several thousand intermediate-mass helium stars in the Milky Way, mostly in binaries, with metallicity and common-envelope ejection efficiency as the dominant shaping factors.
Multi-survey analysis of 157 hot subdwarf binaries yields 23 orbital solutions (11 new) whose mass-period distribution matches post-common-envelope systems, supporting a common-envelope origin.
Simulations overpredict hot subdwarf and RR Lyrae binaries with Gaia astrometric solutions but match red clump stars with high mass functions as potential black hole impostors, implying fewer au-scale RR Lyrae binaries than expected.
A homogeneous search of TESS Cycle 7 20-second cadence light curves identifies 73 rapid oscillators (24 white dwarfs, 31 hot subdwarfs, 18 A-F stars) with measured frequencies and amplitudes after vetting.
Review of UV spectroscopy applications to hot evolved stars, emphasizing HST contributions and the need for continued observations ahead of HWO.
