In his analysis, Stapp considers a set of neutron - scattering events, N in number, and the possible results of measuring the
spins of the neutrons involved along the four
different sets of
axes just delineated.
Stapp's proof, however, requires that the effects of measuring the
spins of the two neutrons along
different axes be considered.
Noel Klingler, a graduate research assistant in physics, George Washington University, and lead author of the B0355 +54 paper, added that the angles between the three vectors — the
spin axis, the line - of - sight, and the velocity — are
different for
different pulsars, thus affecting the appearances of their nebulae.
To reproduce that effect, the team squeezed the cylinder between a pair of rollers, which could circle the cylinder at a rate
different from the one at which the cylinder
spun on its
axis.
Such oscillations occur naturally as the irregular nucleus rotates about its
spin axis and reflects
different amounts of sunlight during a rotation cycle.
The
different Q values also allow the planets to re-align their orbits with the
spin of the star (so that the orbital plane is perpendicular to the star's
spin axis) on a timescale shorter than the orbital period decay, thus explaining why there are many «aligned» hot Jupiters.
Combining the images from the FORS instrument on the ESO telescope using four
different filters with those of other large telescopes, a team of astronomers led by Karen Meech of the Institute for Astronomy in Hawaii found that «Oumuamua varies in brightness by a factor of 10 as it
spins on its
axis every 7.3 hours.
