Giant star. A giant star has a substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature. [1] They lie above the main sequence (luminosity class V in the Yerkes spectral classification) on the Hertzsprung–Russell diagram and correspond to luminosity classes II and III. [2]
Part of a symbiotic binary star system containing a red giant and a white dwarf. As in 2019, with mass 67.54 ± 12.79MJ (0.0523-0.0767 M☉) is the lowest known mass hydrogen-burning star. Luhman 16 B and Luhman 16 A are the closest brown dwarf stars to Earth, and the third-nearest star system to the Solar System.
The planet is about 10% larger than Jupiter, but much hotter because it is 13 times closer to its star than Mercury is to our sun. HD 189733b only takes about two Earth days to complete a single ...
Stars form when dense clumps of interstellar gas and dust collapse under their own gravitational pull. Once a star is born at the center of such a cloud, leftover material forms a swirling disk ...
The temperature was already above 80 degrees and rising. The work of maintaining the public water supply in a heat wave is crucial. But it needs to be done as safely as possible. That means ...
The Jeans instability is a concept in astrophysics that describes an instability that leads to the gravitational collapse of a cloud of gas or dust. [ 1] It causes the collapse of interstellar gas clouds and subsequent star formation. It occurs when the internal gas pressure is not strong enough to prevent the gravitational collapse of a region ...
The Small Magellanic Cloud ( SMC) is a dwarf galaxy near the Milky Way. [5] Classified as a dwarf irregular galaxy, the SMC has a D 25 isophotal diameter of about 5.78 kiloparsecs (18,900 light-years), [1] [3] and contains several hundred million stars. [5] It has a total mass of approximately 7 billion solar masses. [6]
