Prospects of measuring a metallicity trend and spread in globular clusters from low-resolution spectroscopy
Martina Baratella, Deepthi S. Prabhu, Luiz A. Silva-Lima +1
The metallicity spread, or the metallicity trend along the evolutionary sequence of a globular cluster, is a rich source of information to help understand the cluster physics (e.g.…
The X-shooter Spectral Library (XSL): Data Release 3
Kristiina Verro, S. C. Trager, R. F. Peletier +12
We present the third data release (DR3) of the X-shooter Spectral Library (XSL). This moderate-to-high resolution, near-ultraviolet-to-near-infrared ( nm, R 10 000…
A comparison between X-shooter spectra and PHOENIX models across the HR-diagram
A. Lançon, A. Gonneau, K. Verro +14
The path towards robust near-infrared extensions of stellar population models involves the confrontation between empirical and synthetic stellar spectral libraries across the wavel…
NGC 6397: The metallicity trend along the isochrone revisited
Rashi Jain, Philippe Prugniel, Lucimara Martins +1
Recent work has used spectra of about 5000 stars in NGC 6397 that were extracted from a MUSE mosaic to determine the atmospheric parameters for these stars by fitting the spectra a…
The X-Shooter Spectral Library (XSL): Data Release 2
Anaïs Gonneau, M. Lyubenova, A. Lançon +11
We present the second data release (DR2) of the X-Shooter Spectral Library (XSL), which contains all the spectra obtained over the six semesters of that program. This release super…
Stellar atmospheric parameters for 754 spectra from the X-shooter Spectral Library
Anke Arentsen, Philippe Prugniel, Anais Gonneau +8
The X-shooter Spectral Library (XSL) is an empirical stellar library at medium spectral resolution covering the wavelength range from 3000 Åto 24 800 Å. This library aims to provid…
Oxygen-rich Long Period Variables in the X-shooter Spectral Library
A. Lançon, A. Gonneau, S. C. Trager +9
The X-Shooter Spectral Library (XSL) contains more than 800 spectra of stars across the color-magnitude diagram, that extend from near-UV to near-IR wavelengths (320-2450 nm). We s…
Carbon stars in the X-Shooter Spectral Library: II. Comparison with models
A. Gonneau, A. Lançon, S. C. Trager +6
In a previous paper, we assembled a collection of medium-resolution spectra of 35 carbon stars, covering optical and near-infrared wavelengths from 400 to 2400 nm. The sample inclu…
Carbon stars in the X-shooter Spectral Library
A. Gonneau, A. Lançon, S. C. Trager +13
We provide a new collection of spectra of 35 carbon stars obtained with the ESO/VLT X-shooter instrument as part of the X-shooter Spectral Library project. The spectra extend from…
New atmospheric parameters and spectral interpolator for the MILES cool stars
Kaushal Sharma, Philippe Prugniel, Harinder P. Singh
Context: The full spectrum fitting of stellar spectra against a library of empirical spectra is a well-established approach to measure the atmospheric parameters of FGK stars with…
Automatic Determination of Stellar Atmospheric Parameters and Construction of Stellar Spectral Templates of the Guoshoujing Telescope (LAMOST)
Yue Wu, A-Li Luo, Haining Li +10
A number of spectroscopic surveys have been carried out or are planned to study the origin of the Milky Way. Their exploitation requires reliable automated methods and softwares to…
Coude-feed stellar spectral library - atmospheric parameters
Yue Wu, Harinder P. Singh, Philippe Prugniel +2
Context: Empirical libraries of stellar spectra play an important role in different fields. For example, they are used as reference for the automatic determination of atmospheric p…
