In practice, however, big stars are referred to as “blue giants” when they inhabit a specific region of the H-R diagram (top of page), rather than because the star meets a specific set of criteria. Blue Supergiants Spectral Types: OB Life Cycle: Evolved off the main sequence Prevalence...
Star Joy Park hopes to form a good spatial experience through simple terrain creation, but also to combine with plants to form micro-climate conditions, forming a higher terrain that can allow internal circulation wind to amplify. By artificially simulating geographic forms as well as undulating and...
A star during the main part of its life cycle, where it is using hydrogen as a fuel. Location Term Black hole Definition The core of a red supergiant that has collapsed. These are formed if the remaining core has a mass more than three or four times the mass of the Sun. It is so...
This produces, at the end of the main-sequence stage, a more rapid than expected contraction of the core and a gap in the H-R diagram of the cluster immediately after the main sequence. Several clusters, notably M67 and NGC 188, have been used for the study of the interiors models, ...

These rough groupings of stars correspond to stages in their life histories (see belowLater stages of evolution). The second category is identified with what is called the main sequence (see belowHertzsprung-Russell diagram) and includes stars that emitenergymainly by convertinghydrogenintoheliumin ...
This presents a challenge to the designer who must generate the required 15 grams of force at the contact tip, yet keep the bending stresses within the contact arms at a low enough value to achieve a 20K-cycle life. The contact force requirements are met by incorporating a pre-load, so ...
diagram. In more massive stars, this cycle of events can continue, with the stellar core reaching ever-higher temperatures and fusing increasingly heavy nuclei, until the star eventually experiences asupernovaexplosion (see belowEvolution of high-mass stars). In lower-mass stars like theSun, howev...

show strong optical emission lines show the signature of outflows in the ultraviolet on the profiles of the C IV, Si IV, and N V lines. The inclusion of this information in stellar evolution models, beginning in the 1970s, dramatically changed the picture of the life cycle of a massive ...
