Title:
Data Discovery Using the Virtual Observatory Registry
Date:

The GAVO DC team
Description:
There are many ways to access registry data. A fairly powerful one is the Web Interface to the Relational Registry (WIRR for short) at http://dc.g-vo.org/WIRR To actually speak to the VO services discovered, clients speaking the service's protocols are still required. In this tutorial, Topcat plays that role. Starting from a simple use case, we work up to investigating the Tully-Fisher relation in different bands using independently discovered resources.

Description:
An investigation of physical properties of the stars HD 232862 and Vega using the Specflow and Cassis tools.
13. Discovery of Brown Dwarfs mining the 2MASS and SDSS databases

Discovery of Brown Dwarfs mining the 2MASS and SDSS databases

Publisher:
The GAVO DC team
Description:
Brown dwarfs are objects occupying the gap between the least massive stars and the most massive planets. They are intrinsically faint objects so their detection is not straighforward and, in fact, was almost impossible until the advent of global surveys at deep optical and near-infrared bands like SDSS, 2MASS or DENIS among others. We propose here to mine the 2MASS-PSC and SDSS-DR9 databases to identify T-type brown dwarfs through an appropriate combination of colours in the optical and the infra-red, an approach that perfectly fits into the Virtual Observatory.
14. Distance of the Andromeda galaxy

Title:
Distance of the Andromeda galaxy

Publisher:
The GAVO DC team
Description:
Within this use case for high school students and adanced amateurs you measure the linear distance of the Andromeda Galaxy following the steps of the astronomers who first measured it, climbing an important step of the so-called cosmic distance ladder. The use case requires the identification of variable stars of the Cepheid class and the determination of the relation between their period and their intrinsic luminosity.
15. Distance to the Crab Nebula

Title:
Distance to the Crab Nebula

Publisher:
The GAVO DC team
Description:
Within this use case you learn about supernovae, exploding or exploded stars. In particular you will use information on the Crab Nebula (the 1054 aD supernova registered by Chinese astronomers) to derive its distance: an example of how some very important information may be gained from very simple arguments and geometry.

17. Explore the Pleiades with TOPCAT and Aladin

Title:
Explore the Pleiades with TOPCAT and Aladin
Date:

Publisher:
The GAVO DC team
Description:
As stars in open star clusters are formed from the same matter at the same time and have only a small velocity dispersion, it is relatively easy to identify them from the background stars. In this tutorial, we will identify the members of the Pleiades kinematically and get an idea of our success by examining a color-magnitude diagram using TOPCAT, Aladin, and a few VO services.
18. Exploring Gaia data with TOPCAT and STILTS

Title:
Exploring Gaia data with TOPCAT and STILTS

Publisher:
The GAVO DC team
Description:
This tutorial uses data from Gaia DR2 to lead you through some of the capabilities of TOPCAT and STILTS. Use cases covered include a studies of the globular cluster M4 in proper motion space and the open cluster Hyades in the full phase space, matches between Gaia and HST data, and the creation of Hertzsprung-Russell diagrams.

Description:
This tutorial is a comprehensive scientific usecase in which brown dwarf candidates in 2MASS and SDSS are identyfied. The surveys are queried using ADQL, and unncertainties in the data are solved with TOPCAT and Aladin.
