A model of Mira's cometary head/tail entering the Local Bubble
Galaxy Astrophysics (astro-ph.GA)
2011/1/6
We model the cometary structure around Mira as the interaction of an AGB wind from Mira A, and a streaming environment. Our simulations introduce the following new element: we assume that after 200 ky...
FACT -- the First Cherenkov Telescope using a G-APD Camera for TeV Gamma-ray Astronomy (HEAD 2010)
