Rapidly Spinning Star Vega has Cool Dark Equator
Strong darkening observed around the equator of Vega suggests that the fifth brightest star in Earth’s sky has a huge temperature difference of 4,000 degrees Fahrenheit from its cool equatorial region to its hot poles. <b>NOTE: French, German, and Italian translations follow...</b>
Comments:
I wonder if this rotation effects Vega's stellar winds. Are they "confined" to the circumstellar disk?
