A new extensive library of PHOENIX stellar atmospheres and synthetic spectra has been developed, providing high-resolution synthetic spectra for a wide range of stellar parameters. The library is based on the PHOENIX stellar atmosphere code, which allows for detailed modeling of stellar atmospheres and the derivation of synthetic spectra. The library covers a parameter space from 2300 K to 25000 K in effective temperature, 0.0 to +6.0 in log g, and -4.0 to +1.0 in [Fe/H], with additional parameters for alpha element abundance. The spectra are available in a wide wavelength range from 500 Å to 5.5 μm, with high resolution in the optical and near infrared, and lower resolution in the infrared. The library is a work in progress and is expected to be extended to higher effective temperatures. The PHOENIX code was used to calculate model atmospheres and derive synthetic spectra, with a new self-consistent method for micro-turbulence. The library includes a new equation of state and updated atomic and molecular line lists, allowing for more accurate synthetic spectra. The spectra are provided in FITS format, with detailed information on the parameters used in the calculations. The library is available for download and includes both high-resolution and medium-resolution spectra, with a naming scheme that allows for easy identification of the parameters used in each spectrum. The library has been compared to other synthetic libraries, including Kurucz models, and shows good agreement in many cases. The PHOENIX library provides a comprehensive set of synthetic spectra that can be used for a wide range of applications in stellar analysis. The library is a valuable resource for researchers in the field of stellar astrophysics, providing a detailed and accurate set of synthetic spectra for a wide range of stellar parameters.A new extensive library of PHOENIX stellar atmospheres and synthetic spectra has been developed, providing high-resolution synthetic spectra for a wide range of stellar parameters.
