XSL: The X-Shooter Spectral Library

TL;DR

The paper introduces the development of XSL, a comprehensive spectral library covering near-UV to near-IR wavelengths at high resolution, with spectra for nearly 240 stars including many evolved giants.

Contribution

This work presents the progress in building a new spectral library with extensive stellar coverage and high spectral resolution using the X-Shooter instrument.

Findings

Spectra for nearly 240 stars collected.

Over 100 AGB stars included from the Galaxy and Magellanic Clouds.

Spectral coverage from near-UV to near-IR at R ~ 10000.

Abstract

We are building a new spectral library with the X-Shooter instrument on ESO's VLT: XSL, the X-Shooter Spectral Library. We present our progress in building XSL, which covers the wavelength range from the near-UV to the near-IR with a resolution of R ~ 10000. At the time of writing we have collected spectra for nearly 240 stars. An important feature of XSL is that we have already collected spectra of more than 100 Asymptotic Giant Branch stars in the Galaxy and the Magellanic Clouds.
