... It is known from preliminary observations that the period of this binary star is more than 8 hours but less than 12 hours. O. Struve & V. Zebergs (1959, ApJ, 130, 783) measured radial velocities of the two components and get the results presented at the enclosed "sheet of data". ... Plot graph of the velocities of components vs time. 8.2. Find exact orbital period of the components. ... Find exact orbital period, orbital radius and masses of the two components. ...

Structure (\eg density enhancements) clearly forms at the intersection of these filaments. ... What is Dark Matter? ... Testing for the presence of dark matter in the solar neighborhood now becomes an accounting problem The possible sources of this mass in the solar neighborhood are 1) luminous stars, 2) interstellar gas, 3) stellar remnants (mostly white dwarfs) and 4) dark matter: . ...

To locate it, look along the imaginary line between the two end stars on the leading edge of the PloughтАЩs blade (Merak and Dubhe) and Polaris (the North Star), the galaxy M82 (also known as the Cigar Galaxy) along with its companion M81, lies just off this line about a third of the way between the Plough and Polaris. €а€аAs usual, the supernova is far brighter than its home galaxy, appearing as an extra star. ...

The idea of component-oriented programming is that in the course of implementation of various software projects a programmer (or a programmers team) accumulates a library of reused software fragments that are used in different projects. ... To solve such problems there are some special syntax means in Actor Prolog that support component-oriented programming. ... A package in Actor Prolog is a set of classes linked by implication. ... Actor Prolog supports visual component-oriented programming. ...
