1 The Spanish-VO and the VO-Science Francisco Jiménez Esteban CAB / SVO (INTA-CSIC) Suffolk University

2 The Spanish-VO (SVO) IVOA was created in June 2002 with the mission to facilitate the international coordination and collaboration. Organized in working groups, IVOA is the forum where the standards, tools, roadmap, are defined.

3 The Spanish-VO SVO - Officially started in June Development of a VO infrastructure in Spain. Coordination of the activities of the Spanish institutes in the VO framework. Contact-point for the international VO-projects.

4 The Spanish-VO SVO - Led by E. Solano (CAB / INTA-CSIC) Network of almost 200 researchers from 33 institutes Funded by the INTA, the Spanish hgovernment and the EU.

30 VO Science What do I expect from VO tools? Data discovery Data retrieval Data analysis

31 VO Science. Case I Preparation of observations Systematic survey for faint, cold debris disks (similar to Kuiper belt) around nearbystars. 239 IV-V stars. Sample is volume-limited (d < 25 pc; Hipparcos) The dtild detailed analysis of fit faint cold disks require a good knowledge of the stellar properties, like e.g. T eff, luminosity, age, metallicity or activity.

32 VO Science. Case I Preparation of observations

33 VO Science. Case II Discovering new objects of a given class

34 VO Science. Case II Discovering new objects of a given class Metal-poor dwarfs with spectral type later than M7. Hotter than their solar metallicity counterparts. Population II. Useful tracers of the Galactic chemical history. Known around fifty in 2011.

35 VO Science. Case II

36 VO Science. Case II 20 new spectroscopically confirmed UCSDs > 80% success rate after proper motion refinement

37 VO Science. Case III Discovery of peculiar objects Bright objects with peculiar colours and high proper motions are rare in the sky. The closer/brighter the easier to investigate their physical py properties - Blue: Nearby WD, subo, runaway stars, or OB stars in nearby young moving groups. - Red: nearby M dwarfs or RG with high tangential velocity

38 VO Science. Case III Discovery of peculiar objects Cross-matched Tycho-2 and 2MASS 155,000 high proper motion candidates (µ > 50 mas/yr) Reduced proper motion diagram H VT vs. V T K s Blue sources V T K s < blue (OB, sdo, WD) 5 unknown WD or sdo

39 VO Science. Case III Discovery of peculiar objects We confirmed the nature of one sdo (FUSE spectra)

40 VO Science. Case III Discovery of peculiar objects Red sources V T K s > red (M dwarfs and giants) - 5 unknown, probably bl thick-disc and halo giants

41 VO Science. Case III Discovery of peculiar objects

42 VO Science. Case III Discovery of peculiar objects

43 We found from ASAS analysis: 1l long secondary period 1 extremely long period VO Science. Case III Discovery of peculiar objects We confirmed with follow-up observations: 1 RG 1 metal-poor RG

44 VO Science. Case III Discovery of peculiar objects
