WebObservations of optical polarimetric variations of the recurrent X-ray transient A0538-66 during outbursts 99 and 75 are used to investigate the redistribution of gas in the system during periastron passage. The results are consistent with the polarization arising from light in the primary (Be-star) neighborhood which is scattered off a Be-star type disk and a … Earth's apsidal precession slowly increases its argument of periapsis; it takes about 112,000 years for the ellipse to revolve once relative to the fixed stars. Earth's polar axis, and hence the solstices and equinoxes, precess with a period of about 26,000 years in relation to the fixed stars. These two forms of 'precession' combine so that it takes between 20,800 and 29,000 years (and on average 23,000 years) for the ellipse to revolve once relative to the vernal equinox, that is, for th…
