Sentences with phrase «about angular momentum»

REPLY: The length of the cycle looks to be controlled by other forces but the modulation is all about angular momentum.
Information about the angular momentum distribution is inaccessible to direct observations, but it can be extracted from the effect of rotation on oscillation modes that probe the stellar interior.

Not exact matches

In fact our entire local group has way stronger a pull, that supermassive black hole probably was significant in imparting the angular momentum of our galaxy, but that's about it.
Spiral galaxies are found to be strongly rotating, with an angular momentum higher by a factor of about 5 than ellipticals.
The angular momentum is so small that the jet has to be launched from the innermost region of the disk at about 0.05 au from the central protostar, well consistent with current models of the jet launching.
Even if we assume that all the mass of the sun is at its surface on the equation (I'm too lazy to carry out the 3 - dimensional integration over variable density), the solar angular momentum is 2 * 10 ^ 30 kg x 7 * 10 ^ 8 m * 1 * 10 ^ 3 m / s, or about 1.5 * 10 ^ 41 kg - m ^ 2 / s — about a hundred times less than Jupiter's.
As other posters have indicated with the point about how ice lost from ice - caps changes the angular momentum, the movement of water and atmosphere over the surface has an impact on the angular momentum and therefore a major ENSO event will show up in a LOD fluctuation.
Concerning atmospheric angular momentum, it's overall size tells that it can not vary enough to explain variability in LOD beyond about 1 ms. Actual calculations of AAM confirm its role.
I wasn't complaining about your conclusion, only your reasoning leading up to it («Thus only something with a sufficient momentum of inertia can affect angular momentum of the Earth.»)
The 60 year cycle appears to correlate with the Jupiter - Saturn resonance cycle which is about 59 years and 8 months, and obviously affects the scalar sum of the angular momentum of the Sun and nine planets.
«The range of the Sun's orbital angular momentum about the SSB varies from near zero to only 25 % of the Sun's differential angular momentum driving the solar dynamo (Landscheidt 2003).
This is the main driver seen in the angular momentum of the Sun about the SSB.
Our planet as a whole conserves its angular momentum except for the known effects of external torque associated with the lunar - solar tide, which induces a gradual decelerating of the earth rotation velocity at a rate corresponding to the increase in the astronomic length of day (LOD) by about 1.4 millisecond per century (Munk and McDonald 1960).
