Sentences with phrase «orbital periods over»

The analysis of those observations, along with measurements of orbital periods over the next few years, could help recurrent novae beat rival candidates for the role of true type 1a progenitors.

The observed shift in the Hulse - Taylor binary's orbital period over time as it loses energy to gravitational - wave emission.

Not exact matches

The orbit of an Earth - like planet (with liquid water) around close - orbiting Stars A and B may be centered as close as 1.06 AU — between the orbital distances of Earth and Mars in the Solar System — with an orbital period of over 384 days (1.05 years).

In any case, the orbit of an Earth - like planet (with liquid water) around Zeta2 would have to be centered at around one AU — the orbital distance Earth in the Solar System — with an orbital period of just over a year.

Assuming that 15 Sge has a mass equal to Sol's, then such a planet would have an orbital period of about 450 days, or just over 1.2 years.

At that distance from Epsilon Indi and assuming that it has 0.77 Solar - mass, such a planet would have an orbital period of around 199 days (or a bit over half an Earth year).

However, if the existence of a relatively close, second companion (see Star Bc below) around Bab — with an orbital period of 2.2 to 2.9 years or less — is confirmed, then a planetary orbit in Star Ba's water zone may not be stable over the long run.

Note that orbital forcing over the periods covered by these periods is made up of monotonic trends.

[Response: Similar to your first point — coherent statistics over time periods, robust patterns of teleconnections, process by process similarities, coherent emergent properties, quantitative matches in response to large perturbations (volcanoes, orbital forcing, continental configurations etc.).

The authors found that consistent with previous research, changes in solar and volcanic activity, land cover, and incoming solar radiation due to the Earth's orbital cycles were the main contributors to the cooling between the MWP and LIA (the years 900 — 1600), and probably also caused the cooling over the full 2,000 - year period.

Peak insolation from orbital forcing will be significantly lower over the next century than what the Earth received during the peak warm period around 126,000 years ago.

8 Changes in Revolution, Rotation, and Tilt (Page 271) Over a period of about 100,000 years, the orbital path of Earth changes from nearly circular to elliptical and back again.

The drivers of climate over this period are chiefly orbital, solar, volcanic, changes in land use / land cover and some variation in greenhouse gas levels.
