a variable star in the constellation of Andromeda. It is classified as a semiregular variable pulsating giant star, and varies from an apparent visual magnitude of 14.5 at minimum brightness to a magnitude of 9.9 at maximum brightness, with a period of approximately 238.3 days.
In Chinese astronomy, the stars that make up Andromeda were members of four different constellations that had astrological and mythological significance; a constellation related to Andromeda also exists in Hindu mythology. Andromeda is the location of the radiant for the Andromedids, a weak meteor shower that occurs in November.
Alpheratz / æ l ˈ f ɪər æ t s /, [13] [14] or Alpha Andromedae (α Andromedae, abbreviated Alpha And or α And), is a binary star 97 light-years from Earth and is the brightest star in the constellation of Andromeda when Mirach (β Andromedae) undergoes its periodical dimming.
NGC 206 is a bright star cloud in the Andromeda Galaxy, and the brightest star cloud in Andromeda when viewed from Earth.It was discovered by German-born English astronomer William Herschel in 1786 [2] and possibly even two years earlier when he observed "a streak of milky nebulosity, horizontal, or part of the 31st Nebula."
Dylan Hunt, portrayed by Kevin Sorbo, is a member of the All-Systems Commonwealth High Guard.Dylan was born in Visharna-Tarn, a city on the Commonwealth's capital planet, Tarn-Vedra, to a Paradine (a fact unknown to Dylan until the finale of season 4) father employed as a highly paid gardener at the Imperial Gardens and a mother employed as a genetically enhanced high-Gravity World Shuttle pilot.
This star is a red clump giant star that has begun generating energy through the fusion of helium at its core, having passed through the red giant branch of its evolution. [5] It has a stellar classification of K0 IIIb, [ 3 ] with 2.5 [ 5 ] times the mass of the Sun and 10 [ 6 ] times the Sun's radius.
The star, originally known as BD+41 376, received the variable star designation XZ Andromedae in 1924. [10] Photometric periods of Algol variables matches the orbital period of the system. However, in XZ Andromedae have been observed slight period variations that can be reproduced with three different cycles of 137.5, 36.8 and 11.2 years ...
R Andromedae (R And) is a Mira-type variable star in the constellation Andromeda. Its spectral class is type S because it shows absorption bands of zirconium monoxide (ZrO) in its spectrum. It was among the stars found by Paul Merrill to show absorption lines of the unstable element technetium, [11] establishing that nucleosynthesis must be ...
