This orange blob shows the nearby star Betelgeuse, as seen by the Atacama Large Millimetersubmillimeter Array ALMA. This is the first time that ALMA has ever observed the surface of a star and this first attempt has resulted in the highest resolution image of Betelgeuse available. Betelgeuse, also designated Alpha Orionis Orionis, abbreviated Alpha Ori, Ori, is the ninth brighteststar in the night sky and second brightest in the constellation of Orion. Distinctly reddish, it is a semiregular variable star whose apparent magnitude varies between 0. Betelgeuse is one of three stars that make up the Winter Triangle asterism, and it marks the center of the Winter Hexagon. It would be the brightest star in the night sky if the human eye could view all wavelengths of radiation. Classified as a red supergiant of spectral type M1 2, the star is one of the largest and most luminous stars visible to the naked eye. If Betelgeuse were at the center of the Solar System, its surface would extend past the asteroid belt, wholly engulfing the orbits of Mercury, Venus, Earth, Mars, and possibly Jupiter. Calculations of its mass range from slightly under ten to a little over twenty times that of the Sun. It is calculated to be 6. Less than 1. 0 million years old, Betelgeuse has evolved rapidly because of its high mass. Having been ejected from its birthplace in the Orion OB1 Associationwhich includes the stars in Orions Beltthis runaway star has been observed moving through the interstellar medium at a speed of 3. Currently in a late stage of stellar evolution, the supergiant is expected to explode as a supernova within the next million years. In 1. 92. 0, Betelgeuse became the first extrasolar star to have the angular size of its photosphere measured. Subsequent studies have reported an angular diameter apparent size ranging from 0. It is also surrounded by a complex, asymmetric envelope roughly 2. The angular diameter of Betelgeuse is only exceeded by R Doradus and the Sun. Nomenclatureedit Orionis Latinised to Alpha Orionis is the stars Bayer designation. The traditional name Betelgeuse is derived from the Arabic Ib al Jauz, meaning the axilla of Orion, or Yad al Jauz, meaning the hand of Orion see below. In 2. 01. 6, the International Astronomical Union organized a Working Group on Star Names WGSN1. The WGSNs first bulletin of July 2. WGSN, which included Betelgeuse for this star. It is now so entered in the IAU Catalog of Star Names. Microsoft Chart Control Bar Chart Example. Observational historyeditBetelgeuse and its red coloration have been noted since antiquity the classical astronomer Ptolemy described its color as hypkirrhos, a term that was later described by a translator of Ulugh Begs Zij i Sultani as rubedo, Latin for ruddiness. In the nineteenth century, before modern systems of stellar classification, Angelo Secchi included Betelgeuse as one of the prototypes for his Class III orange to red stars. By contrast, three centuries before Ptolemy, Chinese astronomers observed Betelgeuse as having a yellow coloration, suggesting that the star spent time as a yellow supergiant around the beginning of the common era,2. Nascent discoverieseditThe variation in Betelgeuses brightness was first described in 1. Sir John Herschel, when he published his observations in Outlines of Astronomy. From 1. 83. 6 to 1. Betelgeuse outshone Rigel in October 1. November 1. 83. 9. A 1. 0 year quiescent period followed then in 1. Herschel noted another short cycle of variability, which peaked in 1. Later observers recorded unusually high maxima with an interval of years, but only small variations from 1. The records of the American Association of Variable Star Observers AAVSO show a maximum brightness of 0. This variability in brightness may explain why Johann Bayer, with the publication of his Uranometria in 1. Rigel beta. 2. 8 From Arctic latitudes, Betelgeuses red colour and higher location in the sky than Rigel meant the Inuit regarded it as brighter, and one local name was Ulluriajjuaq large star. In 1. 92. 0, Albert Michelson and Francis Pease mounted a 6 meter interferometer on the front of the 2. Mount Wilson Observatory. Helped by John Anderson, the trio measured the angular diameter of Betelgeuse at 0. AU based on the parallax value of 0. However, limb darkening and measurement errors resulted in uncertainty about the accuracy of these measurements. The 1. 95. 0s and 1. Stratoscope projects and the 1. Structure and Evolution of the Stars, principally the work of Martin Schwarzschild and his colleague at Princeton University, Richard Hrm. Brain Msh Software'>Brain Msh Software. This book disseminated ideas on how to apply computer technologies to create stellar models, while the Stratoscope projects, by taking balloon borne telescopes above the Earths turbulence, produced some of the finest images of solar granules and sunspots ever seen, thus confirming the existence of convection in the solar atmosphere. Imaging breakthroughsedit. UVHST images of Betelgeuse showing asymmetrical pulsations with corresponding spectral line profiles. Astronomers in the 1. Antoine Labeyries invention of speckle interferometry, a process that significantly reduced the blurring effect caused by astronomical seeing. It increased the optical resolution of ground based telescopes, allowing for more precise measurements of Betelgeuses photosphere. With improvements in infrared telescopy atop Mount Wilson, Mount Locke and Mauna Kea in Hawaii, astrophysicists began peering into the complex circumstellar shells surrounding the supergiant,3. But it was not until the late 1. Betelgeuse became a regular target for aperture masking interferometry, that breakthroughs occurred in visible light and infrared imaging. Pioneered by John E. Baldwin and colleagues of the Cavendish Astrophysics Group, the new technique employed a small mask with several holes in the telescope pupil plane, converting the aperture into an ad hoc interferometric array. The technique contributed some of the most accurate measurements of Betelgeuse while revealing bright spots on the stars photosphere. These were the first optical and infrared images of a stellar disk other than the Sun, taken first from ground based interferometers and later from higher resolution observations of the COAST telescope. The bright patches or hotspots observed with these instruments appeared to corroborate a theory put forth by Schwarzschild decades earlier of massive convection cells dominating the stellar surface.
