A hypergiant (luminosity class 0 or Ia +) is a very rare type of star that has an extremely high luminosity, mass, size and mass loss because of its extreme stellar winds. The term hypergiant is defined as luminosity class 0 (zero) in the MKK system .
Large-scale learning assessments (LSLAs) is defined as a form of national or cross-national standardized testing that provide a snapshot of learning achievement for a group of learners in a given year and in a limited number of learning domains. [1] [2] The use of these assessments have been increasing around the globe and have also broadened ...
HD 33579 is a white/yellow hypergiant and one of the brightest stars in the Large Magellanic Cloud (LMC). It is a suspected variable star.. HD 33579 lies in a part of the Hertzsprung–Russell diagram referred to as the Yellow Evolutionary Void because stars with that combination of luminosity and temperature are extremely unstable.
The situation, task, action, result (STAR) format is a technique [1] used by interviewers to gather all the relevant information about a specific capability that the job requires.
A yellow hypergiant star, similar to V382 Carinae, that is also visible to the naked eye. CW Leonis: 560 [78] L/T eff: The nearest carbon star. V509 Cassiopeiae: 511 ± 112 [42] AD A variable yellow hypergiant whose size varied from around 680 R ☉ in 1950–1970 to 910 R ☉ in 1977, and later decreased to 390 R ☉ in the 1990s. [79] V382 ...
Rigel and the IC 2118 nebula which it illuminates.. It was once believed that blue supergiants originated from a "feeding" with the interstellar medium when stars passed through interstellar dust clouds, [11] [8] although the current consensus is that blue supergiants are evolved high-mass stars, a natural consequence of stellar evolution, larger and more luminous than main-sequence stars.
Career assessment, in the form of tests and other structured and unstructured tools, can be very useful for those who are uncertain about the array of career possibilities. However, there are some drawbacks to each. At best, the results of individual career assessments provide targeted information that may not address a particular individual's ...
Cygnus OB2 #12 is an extremely luminous blue hypergiant with an absolute bolometric magnitude (all electromagnetic radiation) of −10.9, among the most luminous stars known in the galaxy. This makes the star nearly two million times more luminous than the Sun, although estimates were even higher when the star was first discovered.
