Single X-ray Stars
Main article: Single X-ray starIn addition to the Sun there are many unary stars or star systems throughout the galaxy that emit X-rays. β Hydri (G2 IV) is a normal single, post main-sequence subgiant star, Teff = 5800 K. It exhibits coronal X-ray fluxes.
The benefit of studying single stars is that it allows measurements free of any effects of a companion or being a part of a multiple star system. Theories or models can be more readily tested. See, e.g., Betelgeuse, Red giants, and Vega and Altair.

Famous quotes containing the words single and/or stars:
“Think of admitting the details of a single case of the criminal court into our thoughts, to stalk profanely through their very sanctum sanctorum for an hour, ay, for many hours! to make a very barroom of the mind’s inmost apartment, as if for so long the dust of the street had occupied us,—the very street itself, with all its travel, its bustle, and filth, had passed through our thoughts’ shrine! Would it not be an intellectual and moral suicide?”
—Henry David Thoreau (1817–1862)
“It would be better for men
To be few and live far apart, where none could infect another; then
slowly the sanity of field and mountain
And the cold ocean and glittering stars might enter their minds.”
—Robinson Jeffers (1887–1962)
