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 .
The PRISMA flow diagram, depicting the flow of information through the different phases of a systematic review. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) is an evidence-based minimum set of items aimed at helping scientific authors to report a wide array of systematic reviews and meta-analyses, primarily used to assess the benefits and harms of a health care ...
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.
6 Cassiopeiae A is a white A2.5 type hypergiant. It is about 25 times as massive as the Sun and 200,000 times as luminous. The star is slightly and erratically variable, an Alpha Cygni variable. Not all sources consider 6 Cas to be a hypergiant.
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 ...
Below is a list of the self-report assessments currently offered: [7] Preschool-aged assessments: Child Behavior Checklist for Ages1½-5 (CBCL/1½-5) – To be completed by the child's parent or guardian, as the child is too immature to complete the assessment themselves. Language Development Survey (LDS) – A subsection of the CBCL/1½-5.
Intrinsic variable types in the Hertzsprung–Russell diagram showing the Yellow Hypergiants above (i.e. more luminous than) the Cepheid instability strip. A yellow hypergiant (YHG) is a massive star with an extended atmosphere, a spectral class from A to K, and, starting with an initial mass of about 20–60 solar masses, has lost as much as half that mass.
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.
