These tumors are generally slow growing and behave in an indolent fashion. However, they have the potential to spread, primarily to the liver and when they do, they can be life threatening and difficult to treat with current modalities. A subset of ...

Spinning-up the Envelope before Entering a Common Envelope Phase

We calculate the orbital evolution of binary systems where the primary star is an evolved red giant branch (RGB) star, while the secondary star is a low mass main sequence (MS) star or a brown dwarf. The evolution starts when a tidal interaction causes the secondary to spiral-in. Either a common envelope (CE) is formed in a very short time, or the system reaches synchronization and the spiralin...
