Ionized helium. Monthly Notices of the Royal Astronomical Society, "Bulletin of the IAU Working Group on Star Names, No. Most light sources can be classified into three main types: continuous, absorption, and emission. Alpha Leporis; HR 1865 HD 36673 Data. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The methods to establish the limiting spectral distribution (LSD) of large dimensional random ma-trices includes the well known moment method which invokes the trace formula. The Sun's radius is 695,800km, therefore the star's radius is an estimated 48,509,364.69.km. Using the 2007 distance, the star is roughly 140,314,782.02 Astronomical Units from the Earth/Sun give or take a few. Alpha Leporis (α Leporis, abbreviated Alpha Lep, α Lep), formally named Arneb /ˈɑːrnɛb/,[10][11] is the brightest star in the constellation of Lepus. The figure of 34,894.93 that I have given is based on the value in the Simbad Hipparcos Extended Catalogue at the University of Strasbourg from 2012. The items in red are values that I've calculated so they could well be wrong. It is about 129 times bigger than the Sun , 14 times as massive, and around 32,000 times brighter. The figure is derived at by using the formula from SDSS rather than peer reviewed papers. catalogues and names: Arneb, a Lep, NSV 02128, 11 Lep, HR 1865, HD 36673, SAO 150547, BD -17 1166, FK5: 207, WDS 05327-1749A constellation: Lepus Arneb is a Binary or Multiple star system. Since 1943, the spectrum of this star has served as one of the stable anchor points by which other stars are classified. [16], This is a massive star with about 14 times the mass of the Sun. The Indo-US coudé feed stellar spectral library (CFLIB) madeavailable to the astronomical community recently by Valdes et al.

[6] Alpha Leporis has a stellar classification of F0 Ib,[3] with the Ib luminosity class indicating that it is a lower luminosity supergiant star. The red dot in the diagram below shows where Arneb is situated in the Hertzsprung–Russell diagram. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days). satellite operation launched in 1989 for four years. Zubeneschamali is a hot blue hydrogen-fusing star of the spectral type B8 V. It has a mass 3.5 times that of the Sun and a radius 4.9 times solar. Based on the spectral type (F0Ib) of the star, the star's colour is yellow to white . has done some calculations as to how long it will take going at differing speeds. It was the first confirmed substellar-mass object, with a mass of 20 to 50 times that of Jupiter. The Radial Velocity, that is the speed at which the star is moving away/towards the Sun is 25.10000 km/s with an error of about 0.10 km/s . The star's Galacto-Centric Distance is 7,875.00 Parsecs or 25,685.36 Light Years. The star can be seen with the naked eye, that is, you don't need a telescope/binoculars to see it. Find out more about its ultimate performance. The star can be seen with the naked eye, that is, you don't need a telescope/binoculars to see it. Apparent Magnitude is also known as Visual Magnitude. There is an intimate connection between the atomic structure of an atom and its spectral characteristics. A faint star will have a high number. Mach 1 is the speed of sound, Mach 2 is twice the speed of sound. The value comes from the Hipparcos Extended Catalog. ARNEB "hare" Other Names. Increasing the gap between the two grating sections enables multiple band-pass peaks to appear within the stop band. 10,000 - 28,000. Spectral type: F0 Ib: U−B color index +0.386: B−V color index +0.217: Astrometry; Radial velocity (R v) +23.9 km/s: Proper motion (μ) RA: +3.56 mas/yr Dec.: +1.18 mas/yr: Parallax (π) 1.47 ± 0.14 mas: Distance: 2,200 ± 200 ly (680 ± 60 pc) Absolute magnitude (M V) −6.574: Details; Mass: 13.9 ± 0.8 M ☉ Radius: 129 R ☉ Luminosity Arneb is the 1st brightest star in Lepus based on the Hipparcos 2007 apparent magnitude. The fiber DFB grating is the simplest type of Fabry–Perot (FP) filter. : +1,18 [1] mas/år If you want that in miles, it is about 7,548,801,627,958,805.44, based on 1 Ly = 5,878,625,373,183.61 miles. Arneb (ook bekend as Alpha Leporis of α Lep) is die helderste ster in die sterrebeeld Haas (Lepus), en is sowat 2 218 ligjare van die Son af. The time it will take to travel to this star is dependent on how fast you are going. – Arneb (Alpha Leporis), the most luminous star in Lepus (2.589 mag), is located about 2,200 light years away, and derives its name from the Arabic word for “the hare”. Figure 2. If you used the 1997 Parallax value, you would get an absolute magnitude of -5.40 If you used the 2007 Parallax value, you would get an absolute magnitude of -6.58. Based on the spectral type (B3V + A) of the star, the star's colour is blue . [5], Alpha Leporis is an older, dying star that may have already passed through a supergiant phase and is now contracting and heating up in the latter phases of stellar evolution, or perhaps is still expanding into the supergiant phase. Arneb estimated radius has been calculated as being 69.72 times bigger than the Sun. All messages will be reviewed before being displayed. Absolute magnitude -5.40. The star is moving 1.18 ± 0.08 milliarcseconds/year towards the north and 3.56 ± 0.14 milliarcseconds/year east if we saw them in the horizon. It has been known to produce widely incorrect figures. [17] At an estimated distance of 2,218 light-years (680 parsecs),[1] this yields a physical size of about 129 times the radius of the Sun. Based on the spectral type, we can deduce that the surface temperature of the star is in the order of between between 6,000 and 7,500K based on the notes from Harvard University. Luminosity is the amount of energy that a star pumps out and its relative to the amount that our star, the Sun gives out. The series was discovered during the years 1906-1914, by Theodore Lyman. Estimates place at least 870 Astronomical Units between the stars, resulting in an excruciating long orbital period of … Arneb (Alpha Leporis) - F type star Procyon (Alpha Canis Minoris) - F type star Group 3: Sadalsuud (Beta Aquarii) - G type star Comparing Group 1, 2 and 3 with the standard chart, Group 1 consists of the B and A type stars, in particular Alpha Lyra has the thick lines of an A-type star, and Beta A B-type main-sequence star (B V) is a main-sequence (hydrogen-burning) star of spectral type B and luminosity class V. These stars have from 2 to 16 times the mass of the Sun and surface temperatures between 10,000 and 30,000 K. B-type stars are extremely luminous and blue. [19]. The file is dated 2000 so any differences between this and any other source will be down to the actual source from where the information came from. Exoplanets. The Galacto-Centric Distance is the distance from the star to the Centre of the Galaxy which is Sagittarius A*. 28,000 - 50,000. More information can be found on my dedicated multiple star systems page. T Leporis. However with the 2007 release of updated Hipparcos files, the radius is now calculated at being round 120.05. 1", "Anchor Points for the MK System of Spectral Classification", https://en.wikipedia.org/w/index.php?title=Alpha_Leporis&oldid=988763731, Articles with Chinese-language sources (zh), Articles containing Chinese-language text, Creative Commons Attribution-ShareAlike License, This page was last edited on 15 November 2020, at 02:56. If you need the diameter of the star, you just need to multiple the radius by 2. Spectral type definition, a category for classifying a star, as A star or G star, according to features of its spectrum, as its shape as a function of temperature and wavelength and its absorption spectrum, that indicate the surface temperature of the star and the presence of particular atoms or molecules in its outer layers: principal types are spectral types O, B, A, F, G, K, and M. The star has been identified as being a multi-star system, one in which there is at least one star in close orbit to another star or two or more stars orbiting a central point. The SPECTROMAXx with iCAL 2.0 is used mainly for material testing, determining all elements used in the metal industry including carbon and sulfur. Color Index (B-V) 0.21. The traditional name Arneb comes from the Arabic أرنب ’arnab 'hare'[12] ('Lepus' is Latin for hare). O. Comments may be merged or altered slightly such as if an email address is given in the main body of the comment. The star's name is a traditional/name which has been officially recognised by the I.A.U. There's no register feature and no need to give an email address if you don't need to. The stars may be of equal mass, unequal mass where one star is stronger than the other or be in groups orbiting a central point which doesn't necessarily have to be a star.
