With an effective temperature of 6176 K, HD 205739 is also hotter than the Sun, although it is younger, at an estimated age of 2.84 billion years. The star is rich in iron; its measured metallicity is = 0.19, or 1.55 times the iron detected in the Sun. After analysis of HD 205739's spectrum, it can be concluded that HD 205739's chromosphere (its outermost layer) is not active.

Famous quotes containing the words host and/or star:
“Think of the earth as a living organism that is being attacked by billions of bacteria whose numbers double every forty years. Either the host dies, or the virus dies, or both die.”
—Gore Vidal (b. 1925)
“The eager fate which carried thee
Took the largest part of me:
For this losing is true dying;
This is lordly man’s down-lying,
This his slow but sure reclining,
Star by star his world resigning.”
—Ralph Waldo Emerson (1803–1882)
