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 ...

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 ...

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 ...

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 ...

Experiments have been conducted with a two-dimensional model of a galaxy, consisting of 2000 rods of mass. Varying amounts of differential rotation are given to a bar and a cylindrical galaxy. Spiral ...

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 ...
