'Talk of the Town' (1933), New Yorker feuilleton by E.

(Awkwardly.) There wasn't much else to do where we was.

A man I used to know, a pal of mine, learned me all about the sky. See how it sparkles? It's in kind of a lopsided square with points running up. See that bright blue star up there? That's Vega.

Roy looks up, then points to the zenith.

I never knew there were so many stars in the sky… Under the night sky one romantic evening, they gaze at the heavens: On his way to a planned heist in the Sierra Nevada mountains, Roy Earle (Humphrey Bogart) meets Velma (Joan Leslie). High Sierra (1941), film written by John Huston and W. Under these conditions, stars gradually approach, but never quite reach, a condition of zero rotation.įor main-sequence stars, the decline in rotation can be approximated by a mathematical relation: Thus as the rotation of a star is slowed because of braking, there is a decrease in rate of loss of angular momentum. Stars with a rate of rotation greater than 15 km/s also exhibit more rapid mass loss, and consequently a faster rate of rotation decay.

The star's magnetic field exerts a torque on the ejected matter, resulting in a steady transfer of angular momentum away from the star.

Stars slowly lose mass by the emission of a stellar wind from the photosphere. As the expected life span of a star decreases with increasing mass, this can be explained as a decline in rotational velocity with age. This increase in rotation peaks among young, massive B-class stars. For stars in this range, the measured rotation velocity increases with mass. <
