Warner, D. “Women Astronomers” in Natural History, May 1979, p. 12. The key descriptor will be a URL of the actual image at whatever content provider site it resides. The period (P) of a binary system is related to the masses of the two stars (m1 and m2) and the orbital semimajor axis (mean radius; a) via Kepler’s third law: P2 = 4π2a3/G(m1 + m2). (G is the universal gravitational constant.) From diameters and masses, average values of the stellar density can be calculated and thence the central pressure.
