Young Stars in $\rho$ Ophiuchi: Toward the Completeness down to Substellar Masses
The $\rho$ Ophiuchi molecular cloud hosts the most nearby... -
Prospects for Star Formation Studies with Mid-Infrared Instruments on Large Telescopes
Imaging and spectroscopic observations in the mid-infrared wavelength range (5μm-30μm) offer valuable insight into the origins of stars and planets.... -
Turbulent Radial Mixing in the Solar Nebula as the Source of Crystalline Silicates in Comets
We present a time-dependent model which investigates the thermal annealing of amorphous silicates in the hot regions of the solar nebula and their... -
The Formation of Brown Dwarfs
Numerous brown dwarfs have been found in recent years, re-igniting debate about their origin. A natural way to stunt the growth of a nascent stellar... -
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,... -
Infrared Observation of Hot Cores
We report on mid-infrared imaging of hot cores performed with SpectroCam-10 and TIMMI2. The observations aimed at the detection of thermal emission... -
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... -
Sub-Arcsecond Millimeter Imaging of Disks and Envelopes: Probing the Density Structure
Sub-arcsecond observations at millimeter wavelengths are providing spectacular images necessary to study directly the circumstellar disks and inner... -
Extra-Solar Planetary Systems in the VLT Era
Radial Velocity surveys have revealed 63 exoplanets (M $\sin{i}$... -
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... -
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... -
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... -
The Astronomy Digital Library and the VO
The NASA Astrophysics Data System (ADS) is the central part of the Digital Library in Astronomy. It provides the users with a search system for the... -

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...
