We present spectra of O to M stars, luminosity classes V, III, and Ib in the wavelength range 5800-8900 Å, at approximately 15 Å resolution. We give identifications of the main spectral features and ...

Abstract: The oxygen λ7771–4 Å triplet is a good indicator of luminosity in A–G supergiants. However, its strength also depends on other atmospheric parameters. In this study, we present the ...

This project applies a regression-based approach to explore the relationship between stellar temperature and luminosity. By transforming both features using a logarithmic scale, the goal was to ...

Stellar color is primarily determined by the star's surface temperature; hotter stars emit more blue light, while cooler stars emit more red light, mirroring the behavior of a propane flame. Stars are ...

This release contains the weights for three YOLO models. These models are trained to perform specific tasks related to object detection, luminosity classification ...
