Clusterix 2.0: A Virtual Observatory Tool to Estimate Cluster Membership Probability [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT Clusterix 2.0 is a web-based, Virtual Observatory compliant, interactive tool for the determination of membership probabilities in stellar clusters based on proper-motion data using a fully non-parametric method. In an area occupied by a cluster, the frequency function is made up of two contributions: cluster and field stars ...

Interoperability Tools for the Virtual Observatory
, 2001 Interoperability is one of the key issues in the current efforts to build the Virtual Observatory. We present here some of the tools which already contribute to the efficient exchange of information between archives, databases, and journals.

A Proper Motion Study of the Lupus Clouds Using Virtual Observatory Tools [PDF]
Astronomy and Astrophysics, 2011 Context. The Lupus dark cloud complex is a well-known, nearby low-mass star-forming region, probably associated with the Gould Belt. In recent years, the number of stellar and substellar Lupus candidate members has been remarkably increased thanks to the Cores to Disks (c2d) Spitzer Legacy Program and other studies.

A Search for New Hot Subdwarf Stars by Means of Virtual Observatory Tools II [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 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.

Galaxy morphologies analysis using Virtual Observatory tools
2022In this project we will be using observatory tools to study the photometric and spectroscopic properties of different galaxy morphologies. We will look into a little about galaxies and their different morphological classifications. We study the different aspects that affect galaxy morphology. We will learn about virtual observatory tools and how to use

J-Plus: Discovery and Characterisation of Ultracool Dwarfs Using Virtual Observatory Tools [PDF]
Astronomy and Astrophysics, 2019 Context. Ultracool dwarfs are objects with spectral types equal to or later than M7. Most of them have been discovered using wide-field imaging surveys. The Virtual Observatory has proven to be very useful for efficiently exploiting these astronomical resources. Aims.

Multidimensional indexing tools for the virtual observatory
Astronomische Nachrichten, 2007AbstractThe last decade has seen a dramatic change in the way astronomy is carried out. The dawn of the the new microelectronic devices, like CCDs has dramatically extended the amount of observed data. Large, in some cases all sky surveys emerged in almost all the wavelength ranges of the observable spectrum of electromagnetic waves.
