The author presents a fairly simple physical interpretation of "m splitting" of the frequencies of nonradial oscillations in slowly rotating stars. This lifting of the degeneracy with respect to the azimuthal "quantum number" m by slow rotation is interpreted in terms of azimuthal running waves whose phase velocities are affected by the rotation. Hence,

The masses of neutron stars are limited by an instability to gravitational collapse and an instability driven by gravitational waves limits their spin. Their oscillations are relevant to x-ray observations of accreting binaries and to gravitational wave observations of neutron stars formed during the coalescence of double neutron-star systems.

There are over 900 stars classified as rotating variables within the General Catalog of Variable Stars. The α2 Canum Venaticorum stars are the most numerous, followed by the BY Draconis variables. Only a dozen or so of the FK Coma Berenices type variables are known.

In 1612 Galileo Galilei discovered that the Sun rotates on its axis. He worked this out by watching the movement of sunspots across the solar disk and calculated the solar rotation period to be approximately 25 days on average. For the first time, a body such as a star was found to be imperfect and blemished, and this led over the next two centuries to

Galaxies and the individual stars within them rotate, as evidenced by Doppler broadening of their spectral lines. The sun rotates rather slowly, with an equatorial speed of 2 km/s. Some stars rotate with equatorial speeds in excess of 400 km/s, close to the limit at which matter would be torn off by centrifugal force.

Differential rotation on rapidly rotating stars
Astronomische Nachrichten, 2007AbstractTheories of meridional circulation and differential rotation in stellar convective zones predict trends in surface flow patterns on main‐sequence stars that are amenable to direct observational testing. Here I summarise progress made in the last few years in determining surface differential rotation patterns on rapidly‐rotating young main ...

Recently, experimental evidence has been accumulated that fundamental scalar fields, like the Higgs boson, exist in Nature. The gravitational collapse of such a boson cloud would lead to a boson star (BS) as a new type of a compact object. Similarly as for white dwarfs and neutron stars (NSs), there exist a limiting mass, the Kaup limit, below which a ...
