A high-resolution K-band spectral atlas of massive stars

arXiv:2604.27086

Abstract

A high-resolution (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.
