Title:: The GAVO VO Puzzlers
Date:: 03 Apr 2025 09:45:51
Publisher:: The GAVO DC team
Description:: The GAVO puzzlers are little training problems solvable by standard VO techniques (data discovery, SIAP, Cone Search, TAP). They assume some familiarity with common astronomical concepts (they were originally given out during meetings of the German Astronomische Gesellschaft) but are designed to be solvable using common, standard tools and in reasonable time. Solutions are also given.

Title:: The Global TAP Schema GloTS
Date:: 20 Apr 2023 00:19:19
Publisher:: The GAVO DC team
Description:: The Global TAP schema is an attempt at a simple way to present a union of all TAP_SCHEMA instances globally, where right now GloTS only contains tables and columns. It is primarily intended as a quick (and relatively dirty) way for data collection discovery until other means are ready.

Title:: The HI shells of the Small Magellanic Cloud
Date:: 27 Dec 2024 08:31:12
Publisher:: The GAVO DC team
Description:: This tutorial employs the Aladin VO client to explore neutral hydrogen shells around the SMC; it demonstrates using image servers, catalog servers, and advanced overplotting within Aladin.

ID:: ivo://edu.gavo.org/eurovo/cosadie_jupiter_nass
Title:: The mass of Jupiter
Date:: 02 Apr 2025 14:48:21
Publisher:: The GAVO DC team
Description:: Within this use case you determine the mass of Jupiter by observing the orbits of the Galileian moons and by inserting these data into Kepler's laws.

ID:: ivo://edu.gavo.org/eurovo/cosadie_messier
Title:: The Messier Catalog
Date:: 02 Apr 2025 14:48:21
Publisher:: The GAVO DC team
Description:: Within this use case you meet representatives of the most interesting categories of celestial objects. From stellar clusters to galaxies. All objects are from the Messier catalog that includes some of the most viewed objects of the deep sky.

ID:: ivo://edu.gavo.org/eurovo/ice_moon
Title:: The Moon
Date:: 02 Apr 2025 14:48:28
Publisher:: The GAVO DC team
Description:: Within this case you discover the geometry of the orbit of the Moon and the nature of its phases. As special case of the circumstances of Moon's orbit, the use case introduces the eclipses, both of Moon and Sun.

Title:: The Pleiades open cluster
Date:: 02 Apr 2025 14:48:15
Publisher:: The GAVO DC team
Description:: Within this use case you recognize a physical association of stars close in space as opposed to a superpositon created by projection effects of stars very far one from the others. The key measure is distance derived from parallax. With the true members of the association (open cluster) you create a Herzsprung-Russell diagram as in the tutorial “the stars” (ivo://edu.gavo.org/eurovo/aida_stars). The Herzsprung-Russell diagram of stellar clusters is very important because of the low noise of few unrelated stars. If used in the classroom this advanced use case requires a reasonable understanding of histograms and bidimensional scatter diagrams. It is also rather long to perform from beginning to end.

ID:: ivo://edu.gavo.org/eurovo/aida_galaxies
Title:: The shape of galaxies
Date:: 02 Apr 2025 14:48:15
Publisher:: The GAVO DC team
Description:: Within this use case you discover the shapes of galaxies and their classification according to the Hubble diagram. You are offered sequences of galaxies with different morphologies and are asked to order them. The morphological classification of galaxies is still in use even if we have discovered that the Hubble diagram "per se" has no direct physical or evolutionary meaning. Besides introducing the main shapes of galaxies, the use case offer a demonstration of the classification process, a fundamental tool of astronomers.

Title:: The Sky
Date:: 02 Apr 2025 14:48:15
Publisher:: The GAVO DC team
Description:: The Earth rotates around its polar axis and orbits around the Sun: the sky above us (the celestial sphere) is in constant apparent motion. Stellarium is the perfect tool to demonstrate the motions of the sky, the use of coordinates and to illustrate constellations.

ID:: ivo://edu.gavo.org/eurovo/aida_stars
Title:: The stars
Date:: 02 Apr 2025 14:48:15
Publisher:: The GAVO DC team
Description:: Stars have different colors and luminosities. Following this tutorial we will learn what star luminosity and color are, and which information about stellar evolution we can obtain from them.
