This is a list of coolest stars and brown dwarfs discovered, arranged by decreasing temperature. The stars with temperatures lower than 2,000 K are included. Kirkpatrick et al. 2021 [ 1] has a more complete list of nearby objects with a temperature below 2,400 K. Objects with a temperature below 500 K from this paper were included in this list.
Stellar classification. In astronomy, stellar classification is the classification of stars based on their spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a prism or diffraction grating into a spectrum exhibiting the rainbow of colors interspersed with spectral lines.
This is a list of hottest stars so far discovered (excluding degenerate stars), arranged by decreasing temperature. The stars with temperatures higher than 60,000 K are included.
Color temperature is conventionally expressed in kelvins, using the symbol K, a unit for absolute temperature. Color temperatures over 5000 K are called "cool colors" (bluish), while lower color temperatures (2700–3000 K) are called "warm colors" (yellowish). "Warm" in this context is with respect to a traditional categorization of colors ...
A star is a massive luminous spheroid astronomical object made of plasma that is held together by its own gravity.Stars exhibit great diversity in their properties (such as mass, volume, velocity, stage in stellar evolution, and distance from Earth) and some of the outliers are so disproportionate in comparison with the general population that they are considered extreme.
Blue giant. In astronomy, a blue giant is a hot star with a luminosity class of III ( giant) or II ( bright giant ). In the standard Hertzsprung–Russell diagram, these stars lie above and to the right of the main sequence . The term applies to a variety of stars in different phases of development, all evolved stars that have moved from the ...
Legend. Wolf–Rayet star. Luminous blue variable. O-type star. B-type star. A-type star. F-type star. This list is currently limited mostly to objects in our galaxy and the Magellanic Clouds, but a few stars in other local group galaxies can now be examined in enough detail to determine their luminosities.
R136a1. A near-infrared image of the R136 cluster. R136a1 is at the center with R136a2 close by, R136a3 below right, and R136b to the left. R136a1 (short for RMC 136a1) is one of the most massive and luminous stars known, at nearly 200 M☉ and nearly 4.7 million L☉, and is also one of the hottest, at around 46,000 K.
