	PSR 1913+16 (Site not responding. Last check: 2007-11-06)
		In the case of PSR 1913+16, the orbit is inclined at about 45 degrees with respect to the plane of the sky, and it is oriented such that periastron occurs nearly perpendicular to our line of sight.
		When they are closer together, near apastron, the gravitational field is stronger, so that the pasage of time is slowed down -- the time between pulses (ticks) lengthens just as Einstein predicted.
		The pulsar clock is slowed down when it is travelling fastest and in the strongest part of the gravitational field; it regains time when it is travelling more slowly and in the weakest part of the field.

		This position is the same as the apoapsis of the orbit, but specifically refers to orbits around other stars.
		Viewed from a reference frame where one of the stars is at rest, the secondary star moves in an elliptical orbit.
		The secondary star is at apastron when the two stars have their greatest separation.

		It is not clear whether this figure represents the periastron or the apastron distance or just an average.
		Suggestions from several sources indicate that Mira and its white-dwarf companion have an at least partially symbiotic relationship as the white dwarf does seem to be accreting matter from Mira.
		In the illustrations for this essay, I have only shown visible evidence of accretion when the white dwarf is quite close to Mira (Yes, I am aware that I probably made the accretion disk WAAAAAY too small).

		Similarly, in the orbit of the earth or another planet around the sun, the perihelion is the point of closest approach and the aphelion is the point of farthest recession.
		In the orbit of the stars in a binary star system, the periastron is the point of closest approach and the apastron the point of farthest recession.
		A line connecting the two apsidal points of an elliptical orbit (e.g., the aphelion and perihelion) is called the line of apsides; it is the major axis of the ellipse.

	Rambles: John A. Senneff, The Apastron Reports: Quest for Life (Site not responding. Last check: 2007-11-06)
		The story in The Apastron Reports is an adventure that two brothers share as they discover life on other planets.
		They have a closeknit relationship, and at the end of each chapter they are whisked away from danger and evil to wake up in a new environment.
		Serving a certain religious mindset, the book could have some appeal to the greater public, but would probably need adult participation, reading out loud or group readings, to fully be appreciated.

		To illustrate how objects tend to spend their time near apastron, here’s a home-made mpeg-4 stop-action animation of a peppercorn orbiting a kumquat in an ellipse with e=0.90.
		These orbits all fall in the part of the graph where Proxima’s radial velocity is in the vicinity of -22.1 kilometers per second.
		The “two sigma” orbit is an example of a realization in which Proxima is slightly closer to apastron than periastron.

		During the first observing window the apastron passage occurs during s/c orbit 71 (= first observation) and the periastron passage occurs during s/c orbit 92 (= last observation).
		During the fourth window, apastron occurs during s/c orbit 354 and peri- astron during orbit 375.

		Isochrone fitting using this delta V and temperatures from the spectral types yields 23 \pm 3 mas for the anticipated projected major axis of the system.
		The anticipated separation of 32 mas near apastron should be recoverable even at the 3 mag visual contrast; instead this separation can be no more than 22 mas.

		WR 22 is an eclipsing binary (Gosset et al, 1991) of spectral type WN7+abs + O in the Carina OB1 association.
		In the present proposal we suggest to complement these observations with two additional pointings of WR 22 at orbital phases close to apastron to investigate the impact of intrinsic variability on the X-ray light curve of this system.
		The X-ray luminosity derived from EINSTEIN observations near apastron is 8e32 erg s-1.

	Unique pulsating star discovery
		When the pulsar is near periastron (closest approach to the star), the bursts are more intense, now around 1.4 percent the brightness of the Crab Nebula.
		When the pulsar is near apastron (most distant from the star), the bursts are weaker, down to less than 1 percent of the Crab, almost at the threshold of the BATSE.
		The identification is based on J2058+42's behavior matching that of other Be-pulsar binaries.

	ASTR 3220 Homework 3 Solutions
		(Note: At periastron the low mass star is closest to the primary, and at apastron it is farthest.)
		Ans: Angular momentum J is constant throughout the orbit, which is just an equivalent statement of Kepler's 2nd law.
		If r(min) is the distance from the high-mass star to low-mass star at periastron, and r(max) is the distance at apastron, then equating J at these two points gives: m* v * r(min) = m * V * r(max), where v is the speed at periastron and V is the speed at apastron.
