The habitable zone around yellow dwarfs varies according to their size and luminosity, although the inner boundary is usually at 0.84 AU and the outer one at 1.67 in a G2V class dwarf like the Sun. [19] In a G5V class dwarf -smaller- of 0.95 R☉ the habitable zone would correspond to the region located between 0.8 and 1.58 AU with respect to ...
A G-type main-sequence star (spectral type: G-V), also often, and imprecisely, called a yellow dwarf, or G star, is a main-sequence star (luminosity class V) of spectral type G. Such a star has about 0.9 to 1.1 solar masses and an effective temperature between about 5,300 and 6,000 K (5,000 and 5,700 °C ; 9,100 and 10,000 °F ).
Yellow dwarf systems; F-type main-sequence star systems; The following list includes some of the potentially habitable exoplanets discovered so far.
The yellow-striped pygmy eleuth (Eleutherodactylus limbatus), also known as the yellow-striped dwarf frog, is a species of frog in the family Eleutherodactylidae from closed mesic and xeric forests in Cuba. [1]
The Sun is a G-type main-sequence star (G2V), informally called a yellow dwarf, though its light is actually white. It formed approximately 4.6 billion [a] years ago from the gravitational collapse of matter within a region of a large molecular cloud.
Lygodactylus luteopicturatus G. Pasteur, 1964 – dwarf yellow-headed gecko, yellow-headed dwarf gecko; Lygodactylus madagascariensis (Boettger, 1881) – Madagascar dwarf gecko; Lygodactylus manni Loveridge, 1928 – Mann's dwarf gecko; Lygodactylus methueni V. FitzSimons, 1937 – Methuen's dwarf gecko, Woodbrush dwarf gecko
This temperature range gives the F-type stars a whitish hue when observed by the atmosphere. Because a main-sequence star is referred to as a dwarf star, this class of star may also be termed a yellow-white dwarf (not to be confused with white dwarfs, remnant stars that are a possible final stage of stellar evolution).
Artist's impression of tundra on an inhabited planet around a spectral class F5 star. The habitability of F-type main-sequence star (or yellow-white dwarf) systems is disputed due to the shorter lifetimes (3–8 Gyrs as opposed to 9–15 Gyrs for G stars) and higher levels of UV radiation.
