We present a grid of optical (3200--7200 \AA) synthetic spectra calculated with Tlusty/Synspec. The new NLTE model atmospheres include the most recent hydrogen Stark broadening profiles; were calculated in opacity sampling and limited to pure H/He composition. The grid covers the observed parameter space of (He-)sdB and (He-)sdO stars, therefore it is suitable for the homogeneous spectral analyses of such evolved stars.

TESS Observations of Stochastic Low-frequency Variability in Extreme Helium Stars
astro-ph.SR 2026-05 unverdicted novelty 7.0

TESS data show stochastic low-frequency variability dominates in most extreme helium stars, with characteristic timescales of 0.5-10 days correlating to stellar parameters and matching subsurface convection predictions.
