A search for new hot subdwarf stars by means of virtual observatory tools II [PDF]
Recent massive sky surveys in different bandwidths are providing new opportunities to modern astronomy. The Virtual Observatory (VO) represents the adequate framework to handle the huge amount of information available and filter out data according to specific requirements.

Identification of red high proper-motion objects in Tycho-2 and 2MASS catalogues using Virtual Observatory tools [PDF]
Aims: With available Virtual Observatory tools, we looked for new M dwarfs in the solar neighbourhood and M giants with high tangential velocities. Methods: From an all-sky cross-match between the optical Tycho-2 and the near-infrared 2MASS catalogues ...

New ultracool subdwarfs identified in large-scale surveys using Virtual Observatory tools [PDF]
The aim of the project is to improve our knowledge on the low-mass and low-metallicity population to investigate the influence of metallicity of the stellar (and substellar) mass function. We present the results of a photometric and proper motion search aimed at unearthing ultracool subdwarfs in large-scale surveys.

USING VIRTUAL OBSERVATORY TOOLS FOR ASTRONOMICAL RESEARCH
Construction of the Virtual Observatory (VO) is a great concern to the astronomical community in the 21st century. We present an outline of the concept and necessity of the va and the current status of various VO projects including the 15 national ones and the International Virtual Observatory Alliance (IVOA).
