Sfa Star Charts, W D. Bruton

Faculty Publications

The SFA Start Charts are designed to work anywhere on Earth. Instructions are included on the last two pages. The constellations lines are based in part on those in a book called The Stars by H. A. Rey. These constellation patterns were adopted by Google Sky.


Simultaneous Light And Radial Velocity Curve Solutions For U Cephei, J. B. Rafert, N. L. Markworth Jan 1991

Simultaneous Light And Radial Velocity Curve Solutions For U Cephei, J. B. Rafert, N. L. Markworth

Faculty Publications

The light-curve synthesis approach of Wilson & Devinney has been used to solve simultaneously light and radial velocity curves of the Algol-type eclipsing binary star U Cephei. We have performed eight new differential corrections solutions using the photometric data of Markworth and the radial velocity data of Batten to obtain a consistent set of orbital and astrophysical parameters for the light and velocity curves of this famous system. We find U Cephei to be best modeled using the semidetached (mode 5) system geometry of the Wilson & Devinney program, with a primary rotating at about 5.2 times its synchronous rate, …
