       INTRODUCTION

This data server provides access to the X-exoplanets database. X-exoplanets is a project devoted to collect the X-ray (and a few EUV) observations of stars with exoplanets, and to model the stellar XUV emission in the 1-1200 Å range. The main purpose of this database is to provide the scientific community with coronal radiation models that can be fed into planetary atmospheric models, to test different effects of high energy photons on exoplanets. In this database you can find:

• Stellar X-ray spectra and light curves of stars with exoplanets (for available observations).

• X-ray and EUV luminosities of the stars in the different bands, using coronal models in the range where no real data are available.

• Synthetic high-resolution XUV spectra (coming soon!)

Technical details on the data reduction and the method employed for the coronal models can be find in Sanz-Forcada et al. 2011, A&A 532, A6, http://adsabs.harvard.edu/abs/2011A%26A...532A...6S, and in Sanz-Forcada et al. (2010), in IAU Symposium, vol. 264, p. 478 http://cdsads.u-strasbg.fr/abs/2010IAUS..264..478S.
We are working to provide in the near future synthetic high-resolution XUV spectra. Please do not hesitate to contact us if you wish to use them with your data before they are made available in our website. It is also possible to generate synthetic spectra for objects not currently in our database, under certain assumptions, or based on limited observational information. If you are interested in the use of such spectra you can contact us to evaluate different options to get the best from the data.

       FUNCIONALITIES

        Archive Search

X-exoplanets Archive at CAB is accessed by means of a web-based fill-in form that permits queries object name, coordinates and radius.
It is necessary to check the star or the planet physical parameters options to obtain the corresponding tables with star or planet information.
The users can choose the option of downloading the real X-Ray spectroscopic data and the corresponding ASCII files for the different XMM-Newton and CHANDRA instruments. Besides, the plots of the XMM-Newton light curves are made available, corresponding to the EPIC and MOS instruments, using different time binnings (300s, 600s, 1000s).

        Search Results

As response to the query, the system returns a table in HTML format.
The system provides the following functionalities:

• Name resolver: the system furthermore incorporates a built-in name resolver allowing queries by any of the names provided by the SIMBAD database. By clicking the object name, a list of equivalent names as provided by SIMBAD is displayed.

• Access to SIMBAD: for each star found it is possible to access to the SIMBAD catalogue with extended information about the star.

• Access to Extrasolar Planet Encyclopaedia: for each planet listed there is a link to the Extrasolar Planet Encyclopaedia.

• Multidownload: data in FITS format can be retrieved in groups. For multiple-file retrieval it is possible to include or exclude individual datasets. Multiple-file download generates a file in ZIP format.
