Binary star evolution
WebBSE is a rapid binary star evolution code. It can model circularization of eccentric orbits and synchronization of stellar rotation with the orbital motion owing to tidal interaction in detail. Angular momentum loss mechanisms, such as gravitational radiation and magnetic braking, are also modelled. Wind accretion, where the secondary may ...

Web2.1 Introduction. One of the main sites for accretion disks are interacting binary systems. Indeed, the majority of stars are found in binary systems, and in many cases (up to ~50%), they are close enough that mass flows from one star to the other, in many cases forming an accretion disk. This can happen for a wide variety of different systems ... WebAccreting X-ray pulsars (XRPs) undergo luminous X-ray outbursts during which the luminosity-dependent spectral and timing features of the neutron star’s emission can be analyzed in detail, thus shedding light on the accretion regime at work. We took advantage of a monitoring campaign performed with NuSTAR, Swift/XRT, AstroSat and NICER, to …

A joint research team of Chinese and Australian astronomers has detected a binary star system ejecting a common envelope, a key process of the binary star evolution that could be of great importance to the studies on the universe's expansion and dark energy. … WebGlobular clusters are nearly spherical collections of hundreds of thousands of stars, held together by mutual gravitational attraction. These beautiful objects are nearly free of gas and dust, and contain some of the oldest stars in a galaxy. The first stars within these clusters formed at the same time out of the same interstellar nebula, so ...
WebFigure 12.5. 1 Evolution of a Binary System. The more massive star evolves first to become a red giant and then a white dwarf. The white dwarf then begins to attract material from its companion, which in turn evolves to become a red giant. Eventually, the white dwarf acquires so much mass that it is pushed over the Chandrasekhar limit and ...
