Sentences with phrase «orbital eccentricity for»

James Croll was the major contributor to the orbital variation idea and calculated orbital eccentricity for different latitudes over 3 million years, published in 1867.

Test simulations of the orbits of the three planets around 61 Virginis suggest that the planetary system's orbital configuration is dynamically stable because of low orbital eccentricities for at least 365 million years.

«For icy satellites, resurfacing is generally associated with eccentricity tides, but these are not a viable heat source today for Pluto or Charon, whose orbital eccentricities are fully damped.&raqFor icy satellites, resurfacing is generally associated with eccentricity tides, but these are not a viable heat source today for Pluto or Charon, whose orbital eccentricities are fully damped.&raqfor Pluto or Charon, whose orbital eccentricities are fully damped.»

In fact, the literature is pretty clear that the better analog for the Holocene is actually MIS11 (Droxler), around 400 kya, when orbital eccentricity was quite low as it is today, resulting in a longer interglacial (Berger) with sea levels higher than during the Eemian.

Individual discrepancies have been explained, for example, through interactions between other orbital frequencies such as obliquity and the 413,000 - year period of eccentricity but a unified explanation is lacking.

Insolation does change with orbital eccentricities — there would otherwise be no threshold for bifurcation between states.

The use of the changing orbital eccentricity and obliquity of the ecliptic is nice, for completeness, but over only a century or two those slowly - altering values have little effect.

From first glance the 100 - thousand - year orbital eccentricity cycle had seemed to be a perfect fit for that approximately same interval for inter-glacial periods appearing.

Insolation changes from orbital eccentricities in the Holocene is responsible for SFA.

He doesn't identify eccentricity as such in the title of the paper, but it is there in his orbital forcing model, as the amplitude modulation of precession, and needed for his model to work.

Given that current low orbital eccentricity will persist over the next tens of thousand years, the effects of precession are minimised, and extremely cold northern summer orbital configurations like that of the last glacial initiation at 116 ka will not take place for at least 30 kyr (Box 6.1).
