Database vs Catalog

The database contains as much as possible and the catalog is where we select out to just keep the useful. This means the catalog contains a list of stars with disk measurements where available (as this is better than the simulated values from the HOSTS model since this is what limits us in sensitivity), multiplicity … Continued

Where do we get the data from?

Some sources are already decided e.g. where possible we will take stellar data from SIMBAD, exoplanet data from ExoMercat.. For that we are currently looking into useful catalogs e.g. The TESS Input Catalog (TIC) should be complete for all sources within 20 pc, as long as the objects exist in Gaia DR2 and/or 2MASS. This … Continued

Target Lists

The target list currently used for yield simulations is described in the first of the upcoming serie of LIFE papers currently available at arxiv. The actual list can be viewed here.

What will be inside the database?

The included objects are: stars within 20pc from SIMBAD planets around those stars from ExoMercat and disks around the stars from …(TBD) The included parameters are shown here.

What is the goal / motivation of the database?

Collection of relevant data to optimize target prioritization and ultimately selection for both the LIFE observation (search and characterization phase). Prior to the observation the extraction of target catalogs depending on different scenarios will allow us to make yield estimations to show the viability of the mission. The database is for the main science case … Continued

What type of database will it be?

It will be a relational database following IVOA guidelines. First it will only be accessible via the VO tools (pyvo, TOPCAT,…) and only in the end phase we will look into making it nice and user friendly accessible in a web application or GUI.
