Aims. We present a database of 43 340 atmospheric models (∼80 000 models at the conclusion of the project) for stars with stellar masses between 9 and 120 M⊙, covering the region of the OB main-sequence and Wolf-Rayet stars in the Hertzsprung-Russell diagram. Methods. The models were calculated using the ABACUS I supercomputer and the stellar atmosphere code CMFGEN. Results. The parameter space has six dimensions: the effective temperature Teff, the luminosity L, the metallicity Z, and three…

Stellar Spectra Models Classification and Parameter Estimation Using Machine Learning Algorithms

A comparison of machine learning algorithms used for the classification of stellar synthetic spectra and the estimation of fundamental stellar parameters including T ef f ( K), log ( L / L o ), log g, M / M o , and V rot is presented.



Atlas of CMFGEN Models for OB Massive Stars

We present an atlas of 173 synthetic spectra of stars, with mass from 9 to 120 M⊙, covering the region of the OB main sequence stars in the H–R diagram. The spectra were calculated with the stellar

FITspec: A New Algorithm for the Automated Fit of Synthetic Stellar Spectra for OB Stars

In this paper we describe the FITspec code, a data mining tool for the automatic fitting of synthetic stellar spectra. The program uses a database of 27,000 cmfgen models of stellar atmospheres

PoWR grids of non-LTE model atmospheres for OB-type stars of various metallicities

The study of massive stars in different metallicity environments is a central topic of current stellar research. The spectral analysis of massive stars requires adequate model atmospheres. The

Constraints on the Evolution of Massive Stars through Spectral Analysis. I. The WC5 Star HD 165763

Using a significantly revised non-LTE radiative transfer code that allows for the effects of line blanketing by He, C, O, Si, and Fe, we have performed a detailed analysis of the Galactic Wolf-Rayet

On the consistent treatment of the quasi-hydrostatic layers in hot star atmospheres

CONTEXT: Spectroscopic analysis remains the most common method to derive masses of massive stars, the most fundamental stellar parameter. While binary orbits and stellar pulsations can provide much

Quantitative Spectroscopy of O Stars at Low Metallicity: O Dwarfs in NGC 346

We present the results of a detailed analysis of the properties of dwarf O-type stars in a metal-poor environment. High-resolution, high-quality ultraviolet and optical spectra of six O-type stars in

Grids of model spectra for WN stars, ready for use

Grids of model atmospheres for Wolf-Rayet stars of the nitrogen sequence (WN subclass) are presented. The calculations account for the expansion of the atmosphere, non-LTE, clumping, and line

Atmospheric NLTE models for the spectroscopic analysis of blue stars with winds

Context. Obtaining precise stellar and wind properties and abundance patterns of massive stars is crucial to understanding their nature and interactions with their environments, as well as to
