Abstract:

We present a library of $0.5-2.5~\mu$m digital spectra of cool, mostly variable, giant and supergiant stars which should be useful for spectral synthesis applications, as well as for comparison with theoretical model atmosphere calculations. The library includes carbon stars, Galactic Bulge and Magellanic Cloud stars, and OH/IR stars.

The stars observed cover a range of metallicities and masses. Most variable objects were observed several times, at different phases of their pulsation cycle. We discuss the effects of various fundamental parameters and of variability on the spectra. Based on period-luminosity relations and stellar evolutionary tracks, we tentatively assign initial masses to each object.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access.

An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account.
    In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
