Molecular Cloud Structure: The VLT View
Despite 30 years of molecular spectroscopy of dark clouds little is understood about the internal structure of these objects and consequently about... -
Direct Imaging and Spectroscopy of Substellar Companions Next to Young Nearby Stars in TWA
Direct imaging of substellar companions is possible since several years around nearby stars (e.g. Gl 229) and young stars (e.g. TWA-5). We are... -
The Spectacular BHR 71 Outflow
BHR 71 is a well isolated Bok globule located at $\sim 200$ pc,... -
The Kuiper Belt As An Evolved Circumstellar Disk
In the past decade, more than 400 objects have been discovered in orbit about the sun beyond Neptune. They constitute a vast ring of bodies the... -
From Protoplanetary to Debris Disks
We discuss the physical difference between protoplanetary and debris (Vega-like) disks and consider the course of evolution which leads from the... -
The Physical Structure of a Prestellar Core in IC 5146
We observed an evenly sampled map of the 3 P 1-3... -
VO Activities at the Harvard-Smithsonian CfA
This paper summarizes the VO activities at the Harvard-Smithsonian Center for Astrophysics (CfA). Cfa has expertise covering virtually all branches... -
A C + + Parser for VOTables
This paper provides a brief description of C + + Parser for VOTables. The parser is developed by Persistent Systems in association with IUCAA as part... -
Automatic Detection-Extraction-Classification for a Large Number of Stellar Spectra from Slitless Wide Field Spectroscopy. A Project for AVO
The distribution of spectral types in extended stellar systems in galaxies can be a powerful mine of information regarding:... -

The Astronomical Data Warehouse
The idea of the astronomical data warehouse has arisen as the natural extension of current trends in astronomical data archives, and from an analysis... -
Building the Infrastructure for the National Virtual Observatory: An Information Technology Research Initiative of the National Science Foundation
The U.S. National Science Foundation is sponsoring the development of the infrastructure for the National Virtual Observatory via its Information... -
Information Hub of the Russian Virtual Observatory
The ultimate goal of the Russian Virtual Observatory (RVO) initiative is to provide every astronomer with on-line access to the rich volumes of data... -
Building Interoperable NASA Archives
Over the past decades NASA has developed an extensive set of archives for space astronomy data. These archives are organized along mission,... -
Using XML-Schema to Model Data from Present and Future Astronomical Databases
XML (eXtensible Markup Language) has now become an almost inescapable tool for the exchange of formatted data over the World Wide Web and is now... -
Wide-Field X-Ray Monitoring as a Data Source for the Virtual Observatory
We refer on novel X-ray telescopes with high sensitivity as well as large field of view of order of 1 000 square degrees or even more. The results... -
Laplacean Ideology for Preliminary Orbit Determination and Moving Celestial Body Identification in Virtual Epoch
Any CCD frames with stars or galaxies or clusters and other images must be studied for a searching of moving celestial objects, namely asteroids,... -
HyperLeda: Virtual Instruments for Extragalactic Astronomy
HyperLeda offers a series of tools of interest for Galactic and extra-galactic astronomy. The most prominent service is the LEDA catalogue which... -
A Practical Approach to Catalogued-Data Visualisation
Catalogued data is one of the ways information will be collected from VO. The selected material will contain many physical quantities (columns) and... -
Development of a Multi-Mission Data Server at LAEFF
Astronomical archives have been built independently of each other showing a variety of access levels and policies. This has caused that their remote...
