Sometimes the tried and true methods are still the best, even in observational astronomy. Researchers at the University of Prague demonstrated this recently in a study of the eclipsing binary system V994 Herculis (V994 Her). http://phys.org/news281087801.html Space & Earth Tue, 26 Feb 2013 07:57:04 EST news281087801 The study of the "Demon star", Algol, made by a research group of the University of Helsinki, Finland, has received both scientific and public attention. The period of the brightness variation of this eclipsing binary star has been connected to good prognoses three millennia ago. This result has raised a lot of discussion and the news has spread widely in the Internet. http://phys.org/news256384170.html Space & Earth Wed, 16 May 2012 10:50:58 EST news256384170 (Phys.org) -- Algol, aka the Demon Star, is actually a binary star in the Perseus constellation, and has been the subject of speculation for hundreds of years. Now a group of Finnish researchers propose that the peculiar behavior of Algol was first noted by the Egyptians some 3200 years ago. They suggest, as they describe in their paper uploaded to the preprint server arXiv, that a document known as the Cairo Calendar, shows that not only did the Egyptians know about Algol, but that their observations can be used to further explain the erratic behavior of the binary seen today. http://phys.org/news255163007.html Space & Earth Wed, 02 May 2012 07:37:18 EST news255163007
