ArasBeam is the website dediacted to Be stars amateur observers. Its goal is to organize the spectroscopic observations of Be stars by amateurs from all over the world.
Be stars evolve permanently, and the cause of their evolution is not fully understood. To better understand those evolutions, a regular tracking of as much stars as possible is required : a job accessible to amateur astronomers, and useful for science !
This site, as well as Be Observations Program is developed in collaboration with LESIA team (Observatoire de Paris-Meudon), and is based on data recorded in BeSS database.
You can use this website to study and analyse data already recorded, but you can do still better : join the observers team to multiply our measuements !
If you have questions, if you need questions about instruments, software, targets, and so on, join the distribution list Spectro-l
In the current Corot run (started early November and up to March 2009), there are two Be stars acessible to our instruments : HD51193 and HD51452. This is important to get simultaneously spectra form these two stars, to compare photometry and spectrometry evolutions. Please observe these star in priority, and inform immediately the community if you detect any evolution in the spectra !
I just modified the expected observation period for these two stars : it is now changed to 10 days (365 before).
Go to your telescopes ! (:>)
