iSpec now supports several radiative transfer codes: SPECTRUM, Turbospectrum, SME, MOOG and SYNTHE/WIDTH9.

The Gaia Science Alerts reported in mid-september 2016 three supernovae candidates (among many others) that we observed and confirmed with mercator telescope: Gaia16bic, Gaia16bib and Gaia16biv. The first one is one of the most beautiful SN I have ever observed:

I observed the near earth object (NEO) 410777 2009FD from the Mercator telescope. It was so exciting that I built this animation where we can see it crossing the sky:

New version with only minor bug fixes such as:

  • Continuum fit was failing when the user has the latest version of the python dependencies.
  • The "Find line masks" option from the visual interface was not working.
  • The pre-processing stage of the iSpec pipeline failed when run in parallel.

Several important improvements were implemented in this new version:

  • iSpec now uses the SPECTRUM capabilities to compute synthetic spectra with hyperfine structure and isotopes
  • Alpha elements are automatically enhanced when the analysed stars are metal poor. It follows the standard mixture of the MARCS model atmosphere.
  • A complete automatic pipeline based on iSpec (synthetic spectral fitting technique) is released as an example (included in the virtual machine too).
