	Encyclopedia :: encyclopedia : Beta decay (Site not responding. Last check: 2007-10-10)
		In nuclear physics, beta decay is a type of radioactive decay in which a beta particle (an electron or a positron) is emitted.
		In some nuclei, beta decay is energetically prevented, and in some of these cases the nuclei may undergo double beta decay.
		Beta decay can be considered as a perturbation as described in quantum mechanics, and thus follow Fermi's Golden Rule.

	* Beta Pegasi - (Astronomy): Definition
		The great square is formed by alpha Pegasi, (or Markab, "the Saddle"), beta Pegasi, (or Scheat or Menkhib, "the Horse's Shoulder"), gamma Pegasi, (or Algenib, "the Wing" or "the Side") and alpha Andromedae, (Alpheratz the Princess's Head or Sirrah,...

	51 Pegasi
		It lies near the center (22:57:28+20:46:7.8, ICRS 2000.0) of Constellation Pegasus, the Winged Horse -- northwest of Markab (Alpha Pegasi) and southwest of Scheat (Beta Pegasi).
		As 51 Pegasi has become one of the top 100 target stars for NASA's planned Terrestrial Planet Finder (TPF), images of this star and its position relative to the Milky Way in Earth's night sky are now available from the TPF-C team.
		On February 19, 2006, Margaret Turnbull named 51 Pegasi as a Sun-like star that is old enough to qualify as a top-five candidate for those listening for radio signals from intelligent civilizations, such as the SETI Institute.

	HN Pegasi
		HN Pegasi is a yellow-orange main sequence dwarf star of spectral and luminosity type G0 V. The star may have a mass a little greater than Sol's, about 94 percent of its diameter (Johnson and Wright, 1983, page 699), but around 1.2 times its visual luminosity.
		HN Pegasi may be only around 76 percent as enriched than Sol in elements heavier than hydrogen ("metals") based on its abundance of iron (Beichman et al, 2006, page 37).
		The habitable zone around HN Pegasi where an Earth-type rocky planet could eventually support liquid water on its surface is centered around 1.1 AUs, where it would take somewhat more than an Earth-year to complete its orbit.

	Pegasus, The Winged Horse
		M15 is located west and a little north of Epsilon Pegasi, or Enif, which marks the hoof of the horse’s front leg.
		One of these, NGC 7331, which is located just north of Eta Pegasi, the star that marks the first bend in the rear leg of the horse, is a spiral galaxy very similar in size and form to our own Milky Way.
		Kappa Pegasi is a very close double star, with a faint, distant companion, consisting of a yellow-white and an orange star; but since they are so close together, we see them, even though large telescopes, as one star.

	Pegasus
		Alpha, Beta and Gamma Pegasi, together with Alpha Andromedae, form the well known Great Square of Pegasus, a very useful means of orientation in the sky.
		Beta Pegasi - Scheat changes brightness from 2.4 to 2.6 mag approximately within 30 days.
		Its diameter is estimated at 90 to 110 diameters of the Sun, its distance is 199 light-years.

		Beta Pictoris has been known to have a disk for a long time, maybe decades.
		Spectra of Beta Pictoris show absorption features which are currently believed to be due to cometary like clouds of gas occultating the star from the debris left over from planetary formation.
		HST has observed Beta Pictoris (picture 4) and found the disk to be significantly thinner than previously thought.

	SPA Variable Star Section - SPA 1996 Light Curves
		Beta Pegasi is an Irregular variable - there is no sign of any periodicity in its variations.
		As these results (in which the phases were calculated using the elements in the General Catalogue of Variable Stars) show, the eclipses of RZ Cassiopeiae and Algol are both slightly late : RZ Cassiopeiae’s eclipse is centred on phase 0.02 (30-35 mins late) and Algol’s is centred on phase 0.01 (about 40 mins late).
		These average light curves for Beta Lyrae for the years 1992, 1995 and 1996 show that its eclipses are not occuring at the predicted times - in fact the discrepancy is increasing from year to year.

	Scheat (Site not responding. Last check: 2007-10-10)
		Great Square of Pegasus, rises first to announce the coming appearance of the constellation of the "Winged Horse," which in mythology Perseus rode to rescue Andromeda.
		From Arabic meaning "the shin," the name has nothing to do with the horse, having been misplaced from another constellation, though it is sometimes translated as "the foreleg." At the fainter end of second magnitude (2.42) and the Beta star of Pegasus, variable Scheat averages the second brightest star in the Great Square.
		Unusual for a modestly bright star, Scheat has a fairly low surface temperature of about 3700 degrees Kelvin, 65% that of the Sun, and is categorized as a class M (M2.5) red giant or even "bright giant," its color quite noticeable, especially through binoculars or the telescope.

		Spectra of Beta Pictoris show absorption features which are currently believed to be due to cometary like clouds of gas occultating the star from the debris left over from planetary formation.
		If this is due to orbital motion, these numbers suggest that a planet lies only 7 million kilometers from 51 Pegasi -- much closer than Mercury is to the Sun -- and that the planet has a mass at least half that of Jupiter.

		First stop lies about two degrees west north west of Gamma Pegasi - the 10.5 magnitude galaxy NGC 7814. While this is a spectacular galaxy in pictures, small scope owners should content themselves with looking for a small tuft of cotton floating in intergalactic space.
		If you have a larger scope, be careful that you don't stop at NGC 14. This mag 12 galaxy might confuse you for a minute as it lies almost exactly between 7814 and gamma, but at mag 12.2 (compared to mag 10.8) it's a fair amount dimmer.

	Pegasus (Site not responding. Last check: 2007-10-10)
		The constellation of Pegasus is the seventh one of the whole sky in order of extension, but it doesn't contain any particularly bright stars.
		Its characteristic feature is a big square, whose angles are shown by stars of second and third magnitude, although only three of them belong to Pegasus: the fourth one is the first star of Andromeda and once it was also called delta Pegasi.
		The brightest star of the constellation, however, is not a member of the big square, but it is in the southern part: it is Enif, an orange supergiant, approximately 500 light-years away.

	Constellations: Pegasus, The Winged Horse
		Pegasus is easily recognised by the 4 stars which form an asterism in the shape of a large square known as The Great Square of Pegasus.
		One of the stars of the Great Square used to be delta Pegasi, Alpheratz (Sirrah), but is now assigned to the constellation of Andromeda.
		In 1995, Swiss astronomers Didier Queloz and Michael Mayor announced the discovery of the first extra-solar planet orbiting a star, - 51 Pegasi, in 1995.

		NGC 7594 is located almost a little south of mid-point between 10-Theta Piscium, which is the member of Pisces' Circlet closest to Pegasus, and Alpha Pegasi, which is the southwestern-most member of Pegasus' great square.
		To find NGC 7712, look for 68-Upsilon Pegasi, two-thirds to the center of the Great Square from the northwest corner star (Beta Pegasi), and place the 3 o'clock position on your Telard just east of Upsilon.
		The target is NGC 7275, one-third the way from 29 to 44 Pegasi, and a tick north.
