A high-resolution K-band spectral atlas of massive stars
TLDR
This paper presents a high-resolution K-band spectral atlas of 81 massive stars, covering O2-B1 spectral types.
Key contributions
- Presents a high-resolution (~45000) K-band spectral atlas of massive stars with high signal-to-noise.
- Includes 81 stars, spanning O2-O9 and O2-B1 supergiant spectral and luminosity subclasses.
- The telluric-corrected and reduced spectra are publicly available for research.
Why it matters
This atlas provides a crucial new resource for astronomers studying massive stars. Its high resolution and broad coverage will enable more detailed analysis of stellar properties and evolution. Making the data public accelerates research in this field.
Original Abstract
A high-resolution ($\sim$45000), high signal-to-noise ($>$100) K-band spectral atlas of massive stars is presented. It includes 81 stars consisting of known optical standards, spanning spectral and luminosity subclasses from O2 to O9, and supergiant luminosity and spectral subclasses from O2-B1. The telluric-corrected reduced spectra are publicly available, and are discussed here.
