Far-UV spectroscopy of two hot subdwarfs reveals extreme heavy-element enrichments with patterns matching i-process nucleosynthesis, indicating self-enrichment rather than diffusion.
MWC 656 hosts a hot stripped star companion of 1.48 solar masses instead of a black hole.
ZTF-discovered radial-mode sdB pulsators have mean Teff of 28,300 K and log g of 5.56, placing them at the boundary between V361 Hya and V1093 Her classes with canonical masses and distinguishing them from blue large-amplitude pulsators.
Direct O-C timing analysis yields an orbital decay rate of (-1.97 ± 0.05) × 10^{-12} s s^{-1} in ZTFJ2130, from which a chirp mass of 0.408 ± 0.006 solar masses is derived assuming pure GW emission.
Machine learning classification of TESS data for 6 million stars in the LOPS2 field identifies 28% as candidate variables after filtering out 72% instrumental signals, producing one of the largest automated variability catalogs.
HELM machine learning applied to LAMOST DR1 spectra yields 56 hot subdwarfs (5 He-rich, 51 He-poor) whose parameters confirm two helium sequences.
