2 What is behind Corotsky ?
The tool Corotsky is being developped by GMV as part of the Spanish contribution to COROT The databases behind CorotSky → See the document « Content Description of the Corotsky Asteroseismology and Exoplanet Search Databases » available from the Corotsky web page at CNES: Stars brighter than V=9.5 Centre/Anticentre directions ~12,000 stars Large amount of data from catalogs and dedicated GBO Mostly Implemented Stars with 9.5 ≤ V ≤ 17 Centre/Anticentre directions ~4,000 objects Stars of interest for additional programs Partly Implemented Stars with 12 ≤ V ≤ 16 Centre/Anticentre directions ~10,000,000 stars from cat. BVRI data + identification for ~3,000,000 stars from GBO around principal targets Partly Implemented

Stars of specific interest : Primary candidates Variable stars Peculiar stars Catalogues that define star types in the database Current status : Implementation of the VISAT catalogues (Obs. Vienna; W. Weiss et al.) for the seismology channel 26 referenced startypes

10 Cross-identification
The AP-Exo Table : 9.5 11 17 mV Sismo Database Complete down to V=9.5 Simbad Exoplanet Database EXODAT near principal targets only USNO-A2 (Corot eyes → reference) AP-Exo Table Lists of specific objects from APWG 11 ≤ V ≤ 17 19 contamination Saturating stars for Exo Bright AP Stars From APWG 9.5 ≤ V ≤ 11 Cross-identification with USNO-A2 + Inclusion in (and EXODAT)

11 The AP-Exo Table : Type of star: e.g., eclipsing binary, sdB star, PMS star, (whatever is relevant for Corot) Preferred Name for the star (only one name) B and R photometry as provided by the USNO-A2 catalog (for consistency checks) Ref.name V Startype(s) USNO-A2 Number RA (°) DEC (°) B R KPD 13.83 sdB star 13.6 13.9 Cross-identification with USNO-A2. Provides the link with the Exoplanet database effectively used to select targets in the Exoplanet field. Coordinates as provided by the USNO-A2 Catalog. Ensures homogeneity of the coordinates In the AP-Exo Table.

12 To do list for the Sismo / AP-Exo DBs
Seismology Database : 1. Implement missing methods for star fundamental parameter determinations Detailed analysis (Bruntt et al.) : no data received (1st quarter 2005?) OB Star Line Fitting (Lefever et al.) : no data received (1st quarter 2005?) MV from literature (C. Soubiran ?) : no data received Strömgren / phystar (Jordi et al.) : no data received (1st quarter 2005?) 2. Complete the DB description document. Contribution of each group/person who provided fundamental parameters: write a short description (~ 1 page) of the method employed, including references to any related published work. AP-Exo table implementation : 1. Implement the new lists of AP potential targets cross-identified with USNO-A2 2. Migrate the brightest AP stars (9.5 < V < 11) to the seismology database
