The Virtual Observatory Data, Standards and Tools a technical - user point of view [PDF]

open access: yesProceedings of the International Astronomical Union, 2010
AbstractIn 2002 the International Virtual Observatory Alliance (IVOA) has been created in order to gather efforts on data standardization and dissemination. Since then, the virtual Observatory allowed to spread validated data all over the world and to use data from everywhere from earth.

A Virtual Observatory Census to Address Dwarfs Origins (AVOCADO) [PDF]

open access: yesAstronomy & Astrophysics, 2013
(Abridged) AVOCADO aims at establishing firm conclusions on the formation and evolution of dwarf galaxies by constructing and analysing a homogeneous, multiwavelength dataset for a statistically significant sample of approximately 6500 nearby dwarfs (M_i > -18 mag).

Pulsating stars and the Virtual Observatory [PDF]

open access: yesEPJ Web of Conferences, 2017
Virtual Observatory is one of the most used internet-based protocols in astronomy. It has become somewhat natural to find, manage, compare, visualize and download observations from very different archives of astronomical observations with no effort.

Computational platform of the Mexican Virtual Solar Observatory [PDF]

open access: yesGeofísica Internacional, 2008
The Mexican Virtual Solar Observatory (MVSO) is an ongoing project whose goal is to provide a service based on numerical simulations database that can help to model an interpret solar phenomena. In this paper we describe the computational backbone of the

Identification and characterization of low mass stars and brown dwarfs using Virtual Observatory tools [PDF]

open access: yes, 2015
Context Two thirds of the stars in our galactic neighborhood (d < 10 pc) are M-dwarfs which also constitute the most common stellar objects in the Milky Way. This property, combined with their small stellar masses and radii, increases the likelihood of detecting terrestrial planets through radial velocity and transit techniques, making them very ...

Searching for unknown counterparts in X-ray binary systems using Virtual Observatory tools [PDF]

open access: yes, 2015
In the framework of an ongoing programme, we have developed strategies to discover and characterize optical/infrared unknown counterparts to X-ray binary systems using the standard tools of the Virtual Observatory. First, we have selected some potential candidates from different X-ray catalogues.
