Stellar Components
Rho Coronae Borealis is a Solar twin, yellow dwarf star of the spectral type "G0-2Va". The star is thought to have only 95 percent of the Sun's mass, along with 1.31 times its radius and 1.61 of its luminosity. It may only be 51 to 65 percent as enriched with elements heavier than hydrogen (based on its abundance of iron) and may be somewhat older than the Sun at around six billion years old.
In 2000, preliminary Hipparcos astrometrical satellite data indicated that the orbital inclination of the star's companion was 0.5°, implying that its mass was as much as 115 times Jupiter's. Such a massive body would have to be a dim red dwarf, not a planet. However, this scenario is statistically very improbable, and the claim has not been independently verified.

Famous quotes containing the word components:
“Hence, a generative grammar must be a system of rules that can iterate to generate an indefinitely large number of structures. This system of rules can be analyzed into the three major components of a generative grammar: the syntactic, phonological, and semantic components.”
—Noam Chomsky (b. 1928)
