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

14. TBD for the Sismo/AP/Exo DBs
Seismology Database :
1. Implement missing methods for star fundamental parameter determinations
OB Star Line Fitting (Lefever et al.) : first data received last Friday (1st & 2nd long runs)
Detailed analysis (Bruntt et al.) : no data received (when?)
MV from literature (C. Soubiran ?) : no data received (any plans?)
Strömgren / phystar (Jordi et al.) : data should arrive soon
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 refs. to any related published work.
AP-Exo table :
1. Implementation of the new lists of AP potential targets cross-identified with USNO-A2
Are all the stars from additional programs approved by the SC in the database?
2. Migration of the brightest AP stars (9.5 < V < 11) to the seismology database
EXOSKY Database :
1. Completion of the sky coverage
2. Link with the AP-Exo table

15. The AP-Exo Table
Type of star: e.g., eclipsing binary, sdB star, PMS star, …

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.
