Next: Mass change Up: Evolutionary Scenarios of Binary Previous: Stellar Winds From Normal . As mentioned earlier, the duration of the binary evolutionary stage (say, I+I) is determined by the faster evolving component , where is the time each component spends at the corresponding evolutionary stage. ... Next, we should calculate the mass change for the slower evolving companion, the orbital semi-major axis and the eccentricity. Mass change . Semi-major axis change . ...

The rotation of the stellar component of galaxy is obtained from the compilation of internal stellar kinematics . The rotation of the gaseous component is given in the parameter vmaxg , and the stellar velocity dispersion in vdis . For disk-like galaxies (eg. mostly disks of spiral), the apparent rotation may be converted into the true (physical) rotation using the inclination given in the parameter incl . HyperLeda .
