What kind of star is Alpha Andromedae?
Other Characteristics. Alpheratz is a B-type star of spectral type B8IVpMnHg. It is classified as a mercury-manganese star which contains abnormally high levels of mercury, manganese, and other elements such as gallium and xenon being the brightest mercury-manganese star known.
What is the brightest star in Andromeda?
Andromeda, in astronomy, constellation of the northern sky at about one hour right ascension and 40° north declination. The brightest star, Alpheratz (from the Arabic for “horse’s navel”; the star was once part of the constellation Pegasus), has a magnitude of 2.1.
Is Arcturus red?
Arcturus is a red giant star in the Northern Hemisphere of Earth’s sky and the brightest star in the constellation Boötes (the herdsman). Arcturus is also among the brightest stars that can be seen from Earth.
What type of star is Mirach?
Beta Andromedae/Spectral type
Mirach is a red giant star of spectral type M0 III. It is also a semiregular variable star, having an apparent magnitude of 2.05, which sometimes varies from magnitude 2.01 to 2.10. Its absolute magnitude is -1.76.
What is the biggest star in the Andromeda galaxy?
It’s Alpheratz, the brightest star in the constellation Andromeda. Many people use this star to locate the Andromeda galaxy in the night sky. While it appears as a single star to the unaided eye, Alpheratz is actually a tight double star system.
How many planets does Andromeda have?
A star in the Andromeda galaxy has a “companion” with six times the mass of Jupiter. There’s no end to the ingenuity of these astronomers. We’ve now spotted some 300 extra-solar planets, with rate of discovery increasing at an extraordinary rate.
What planets are in Andromeda galaxy?
Astronomers announced a possible planet in the nearby Andromeda galaxy in 2009, but its presence has not yet been confirmed. So this makes the newly found planet, called HIP 13044 b, the first to be discovered around a star apparently from another galaxy.
How bright is Vega?
Vega, also called Alpha Lyrae, brightest star in the northern constellation Lyra and fifth brightest in the night sky, with a visual magnitude of 0.03. It is also one of the Sun’s closer neighbours, at a distance of about 25 light-years. Vega’s spectral type is A (white) and its luminosity class V (main sequence).
Why is Arcturus flickering?
Notice that Arcturus is an orange-colored star. The atmosphere refracts or splits the stars’ light to cause these stars to flash in the colors of the rainbow. At mid-northern latitudes, scintillating Arcturus adorns the western evening sky all through October.
Is Mirach visible from Earth?
Beta Andromedae, Latinized from β Andromedae, and officially named Mirach /ˈmaɪræk/, is a prominent star in the northern constellation of Andromeda. It is northeast of the Great Square of Pegasus and is potentially visible to all observers north of latitude 54° S.
Which is the brightest star in Alpha Andromedae?
With a combined apparent magnitude of 2.06, it is one of the two brightest stars in the constellation, along with the variable red giant Mirach (Beta Andromedae). Alpheratz lies at a distance of 97 light years from Earth.
What kind of star is Alpheratz in Andromeda?
Alpheratz is a Star type star. Alpheratz is a B9P star based on the spectral type that was recorded in the Hipparcos star catalogue. Alpheratz is a main star in the constellation Andromeda and makes up the constellation outline. Based on the spectral type (B9p) of the star, the star’s colour is blue .
Where is the Andromeda constellation in the sky?
Andromeda constellation. α Andromedae, labeled Sirrah, is at the lower right of the constellation, bordering Pegasus. The location of α Andromedae in the sky is shown on the left.
Which is the Bayer name for Alpha Andromedae?
α Andromedae (Latinised to Alpha Andromedae) is the star’s Bayer designation. Ptolemy considered Alpha Andromedae to be shared by Pegasus, and Johann Bayer assigned it a designation in both constellations: Alpha Andromedae (α And) and Delta Pegasi (δ Peg).
