A few weeks ago, Dr I. W. Roxburgh questioned an earlier argument by Professor R. H. Dicke that the observed flattening of the Sun would account for part of the rotation of the orbit of Mercury ...

ABSTRACT About 30.5 days of nearly uninterrupted broadband photometry of the solar‐type star κ1 Ceti, obtained with the MOST (Microvariability and Oscillations of Stars) satellite, shows evidence for ...

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 ...

In its outer layers the Sun has a rotation pattern that scientists refer to as `latitudinal differential rotation’. This means that different latitudes rotate at different rates. While at the Sun’s ...

For instance, the equator completes one full rotation in about 25 days, while the poles take about 35 days. This differential rotation plays a key role in driving the Sun's magnetic activity ...

The Sun rotates the fastest at the equator, whereas the rotation rate slows down at higher latitudes and is the slowest as the polar regions. But a nearby Sun-like star V889 Herculis, some 115 light ...
