How did venus lose its angular momentum?
Venus now has a retrograde and negligible spin, but it very likely started with a typical planetary spin: prograde and with a 10- to 20-hour period. The usually assumed mechanism of solar tidal friction is quite insufficient to remove this angular momentum. Instead, we postulate capture of a moonlike object from an initially retrograde orbit: it would despin Venus and suddenly transform the pla...
متن کاملOn the " Initial " Angular Momentum of Galaxies
Spherical density profiles and specific angular momentum profiles of Dark Matter halos found in cosmological N–body simulations have been measured extensively. The distribution of the total angular momentum of dark matter halos is also used routinely in semi–analytic modeling of the formation of disk galaxies. However, it is unclear whether the initial (i.e. at the time the halo is assembled) a...
متن کاملHow aphids lose their marbles.
Insects provide examples of many cunning stratagems to cope with the challenges of living in a world dominated by surface forces. Despite being the current masters of the land environment, they are at constant risk of being entrapped in liquids, which they prevent by having waxy and hairy surfaces. The problem is particularly acute in an enclosed space, such as a plant gall. Using secreted wax ...
متن کاملEnergy and Angular Momentum Transfer in Binary Galaxies
We have numerically studied tidal effects of a massive perturber on a satellite galaxy. The model consists of a spherical satellite galaxy and a point mass perturber and the encounter is non-penetrating. A wide range of density ratios and eccentricities of the relative orbits have been considered. The disruption of the satellite galaxy has been observed when the numerical value of the fractiona...
متن کاملThe Origin and Distribution of Angular Momentum in Galaxies
Cold Dark Matter with a large cosmological constant (ΛCDM) appears to fit large scale structure observations well. Of the possible small scale problems, the Central Cusps and Too Many Satellites problems now appear to be at least partly solved, so Angular Momentum has become the most serious remaining CDM problem. There are actually at least two different angular momentum problems: A. Too much ...
