|Sebastián lives in Buenos Aires, the capital city of Argentina. He first became a member back in 1998 when he found out about the AAVSO from a local astronomy club. He was a very active observer at that time although now is more devoted to data-mining and catalogue work.|
CAMBRIDGE, Mass. (October 14, 2019)—Compiling together multiple pieces of information for each of a million-plus objects is no easy or quick task, but that is exactly what Sebastián Otero, Patrick Wils, Patrick Schmeer, and Klaus Bernhard did.
The Star Finder is a web tool that you can use to get direct access to some of our most popular and useful web applications.
The Variable Star Index is the largest amateur-led project to catalog and detail every variable star known in the Galaxy. It was launched in 2005 by importing as many catalogs of variable stars as were available. Since then, the number of sky surveys and new variable star discoveries has grown, as have the number of amateur and professional researchers finding new variable stars. In eleven years, VSX has grown to a catalog of almost 400,000 variable records.
When searching for a star in the International Variable Star Index (VSX) or reporting observations to the AAVSO International Database via WebObs, it is not possible to enter a Greek letter if the star has a Greek letter as part of its name – one cannot search for “µ Cep” or “ν Pav”. There has been ongoing confusion about how to spell out some of the Greek letters used in star names, and in particular about how to spell out µ and ν.
