SLAM-payne for hot stars in LAMOST J/A+A/698/A300 ivo://CDS.VizieR/J/A+A/698/A300 doi:10.26093/cds/vizier/bc-nt/ldaa CDS Sun W. 2026-08-03T06:55:04Z 2025-06-23T07:58:58Z CDS support team CDS, Observatoire de Strasbourg, 11 rue de l'Universite, F-67000 Strasbourg, France cds-question@unistra.fr b-stars Early-type stars are key drivers of Galactic chemical evolution, enriching the interstellar medium with alpha elements through powerful stellar winds and core-collapse supernovae, fuelled by their short lifetimes and high masses. However, their spectra remain challenging to analyse due to rapid rotation, weak metal lines, and non-local thermodynamic equilibrium (NLTE) effects. While large spectroscopic surveys provide extensive low-resolution data, extracting reliable parameters remains difficult due to methodological limitations for hot stars. Our goal is to develop a unified framework that combines data-driven and synthetic spectral approaches to determine atmospheric parameters and abundances for hot stars using low-resolution spectra, thereby addressing limitations in current methodologies while retaining critical spectral information. We present a hybrid approach integrating the Stellar LAbel Machine (SLAM) and the Payne frameworks, for low-resolution (R~1800) spectra from LAMOST DR9. Our method preserves full spectral information including Balmer series and metal-line blends, employing neural-network interpolation for efficient parameter estimation (Teff, logg, and v sin i) and abundance determination for O, Mg, Si, and Fe, across 8000K-20000K. We derive stellar parameters and abundances for 315822 stars with S/N~10 in the r-band. Among these, we identify 3564 blue horizontal branch candidates, over 90% of which align with stellar evolutionary models of horizontal branch stars. Additionally, we detect abundance trends ([alpha/Fe]-[Fe/H]) that exhibit temperature-dependent systematics and a distinct alpha-poor stellar population within 0.0<=[Fe/H]<=0.5dex. The radial abundance gradients are negative and consistent with that derived from Cepheids, with a slope of -0.070+/-0.007 in [Fe/H] in the region 6<=R_GC_<=15kpc. 2025A&A...698A.300S https://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/698/A300 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to I/355 : Gaia DR3 Part 1.
