	Delta Vel (Site not responding. Last check: 2007-09-15)
		Delta Velorum is the second brightest star of Vela (the Sails, the northeastern portion of ancient Argo, the Ship), and is topped in its constellation only by Regor, Gamma-2 Vel.
		Delta Velorum B traces a clockwise apparent relative orbit around more massive Delta Vel A (the bright naked-eye star), whose position is indicated by the cross.
		Delta Vel A is also double (an eclipsing binary), while far outside the image lurks another distant double that circulates around the pair shown here, making Delta Velorum a quintuple star.

	Delta Scuti star
		Delta Scuti stars are Population I objects of spectral type A0 to F5 and lie in the lower part of the instability strip, either on the main sequence or among the subgiants and giants.
		The prototype of the class, Delta Scuti itself, is a widespread triple system at a distance of 187 light-years.
		Delta Scuti A (spectral class F2, visual magnitude 4.71, luminosity 33 times that of the Sun, mass 2.3 solar masses) has two main periods of 4.65 and 4.48 hours with others of 2.79, 2.28, 2.89, and 20.11 hours; its overall change in luminosity is only 0.2 magnitudes.

		Delta Scuti stars are pulsating variables of spectral types A to early F with luminosity classes V to III.
		From searches for Delta Scuti-like variability among open cluster stars (Breger 1972, Slovak 1978) it could be deduced that about 30% of all stars with spectral types of A2 to F0 on the Main Sequence are pulsators.
		The first clues, that Delta Scuti stars are also nonradial pulsators, came from the studies of the stars 14 Aur and 1 Mon.

	SPACE.com -- Confused, Galileo Uncovers a Star"s True Identity
		Delta Velorum is one of about 150 bright stars that Galileo is programmed to recognize by their brightness and their position in relation to other stars.
		On the day when Delta Velorum vanished from Galileo's scanner, the craft had been tracking only two stars, so it was confused until it received instructions from ground control.
		Delta Velorum, in the Southern Hemisphere constellation Vela, the sail, was previously known to be part of a tight grouping of at least five stars.

	Vela
		Sometimes observers associate the lower two stars, kappa Velorum and delta Velorum, with iota Carinae and epsilon Carinae, and believe they are looking at the Southern Cross.
		Although Vela does not make much of a sight in the southern skies, it does have a number of notable objects, including the brightest Wolf-Rayet star, an optical pulsar, and a pulsating variable which is the prototype of an entire class of cepheids.
		It's five degrees east of gamma Velorum, and about one degree north, in the middle of a particularly rich area of the sky, but clearly the brightest star in the area.

		The AAVSO called delta Velorum the brightest variable star discovered visually in the 20th century [8] and, since it is brighter than the famous eclipsing binary star Algol, it is arguably the brightest eclipsing variable now known.
		The same summer that the delta Velorum discovery was made, the same sharp-eyed Argentine amateur astronomer also helped discover the variability of the star delta Scorpii [9].
		Below is a graph of data for delta Scorpii during a part of this time period.

		Abstract: From visual and Galileo star scanner observations the principal component of the bright multiple star delta Velorum is found to be an eclipsing binary, in an eccentric orbit, with a period of 45.150 days.
		Abstract: {delta} Scorpii is a previously unremarkable early-B star that underwent a sudden, large visual outburst and transitioned to a strong Be-state in mid-2000.
		{delta} Sco is also a long-period visual binary star, whose orbit was interferometrically determined by Hartkopf, Mason, and McAlister (1996) and spectroscopically by METAL; the period is 10.58 years, and the eccentricity is extremely high.
