In 2014, the XMM-Newton mission observed Altair, showing that the star has a corona (outer atmosphere) that changes depending on magnetic and rotational activity.

Is Vega a fast rotating star?

Vega is also a fast rotater. In 2006, astronomers discovered it is whirling around so quickly — every 12.5 hours — that its equator is many thousand degrees cooler than its poles. If the star rotated just 10 percentage points faster, it would be at its critical rotation speed — the point at which the star would self-destruct due to its fast rotation. The star is sometimes cited in the literature as a comparison to the rotation of other stars, such as the slowly rotating KIC 11145123.
