It seems Madam Mother Nature has baffled us kids yet again. Just when Astronomers were somewhat confident in explaining stellar evolution and behavior, comes along that proverbial Monkey wrench. Normally I'll post the text as well as the link but in this case one must view the link as the photography is utterly astounding to say the least and therefore crucial to the story. http://space.com/scienceastronomy/aa...st_030526.html -- Keith ... I seem to have become enamored of the idea of celestial impacts being an important part of stellar system evolution: From: Robert Clark ) Subject: Neutron star kicks, a proposal. Newsgroups: sci.astro, sci.physics, sci.physics.relativity Date: 2000/07/25 http://groups.google.com/groups?th=94e8250113c096d5 One possibility for V838 Mon is that the "explosions" are due to planetary impacts. This would be consistent with the molecular species found within the shells: Strangest Star Known is the 'Talk of Astronomy' By Robert Roy Britt Senior Science Writer posted: 05:00 pm ET 26 May 2003 "In the expelled shells, his team has found evidence of water, carbon monoxide, silicates similar to what's found in Earth's insides, and other substances in mixtures and quantities never before seen around novae or supernovae." http://space.com/scienceastronomy/aa...st_030526.html There is also another indication of planetary impacts that I'll post about in a day or so. Bob Clark ================================================== ====================== Giant star caught swallowing three planets. 12:20 17 September 03 NewScientist.com news service. "A giant star has been caught in the act of swallowing three planets, one after the other, with each "meal" accompanied by a massive eruption. "It has been suggested in the past that stars might engulf planets in this way, but we believe we have actually caught this action for the first time," says Alon Retter of the University of Sydney, Australia. "The star, known as V838 Monocerotis, is about 20,000 light years from Earth. In January 2002, it temporarily became the brightest star in the Milky Way, 600,000 times more luminous than the Sun. At the time, astronomers struggled to explain the spectacular explosion." .... "Retter and Marom describe their analysis in a letter accepted by the Monthly Notices of the Royal Astronomical Society." http://www.newscientist.com/news/news.jsp?id=ns99994172 Their paper available he A model of an expanding giant that swallowed planets for the eruption of V838 Monocerotis.
