Astronomers from the Indian Institute of Astrophysics have mapped the Sun's differential rotation using 100 years of data from the Kodaikanal Solar Observatory. They discovered that the Sun's equator ...
Spinning around: the green arrows represent rotation speed in the stellar convection zone. Differential rotation is inferred from the oscillatory motions of the star seen as orange/blue shades on the ...
The interior of the Sun does not rotate at the same rate at all latitudes. The physical origin of this differential rotation is not fully understood. It turns out, long-period solar oscillations ...
The evolution of active regions generally has prevented the unambiguous detection of differential rotation by tracer or spectroscopic methods in disk-integrated solar and stellar observations. However ...
In a groundbreaking discovery, Indian astronomers have mapped the variation in the rotation speed of the Sun’s chromosphere from the equator to the poles using 100 years of data from the Kodaikanal ...
Our grasp of how stars rotate is "insufficient," with implications on our ability to understand the causes of phenomena on the sun like solar flares and coronal mass ejections that cause aurora and ...
What do we know about distant stars aside from their brightness and colors? Is our Sun a typical star? Or does it show certain properties that make it special, or maybe even unique? One property that ...
The Sun’s differential rotation pattern has puzzled scientists for decades: while the poles rotate with a period of approximately 34 days, mid-latitudes rotate faster and the equatorial region ...
