Sentences with phrase «orbital parameters»

We also assess possible orbital parameters for each of the four planets independently.

By tweaking orbital parameters and running their model repeatedly, the team could make some statistical predictions about the car's future path.

Each of these has their own strengths, making them useful for detecting exoplanets with different orbital parameters.

How about small orbital parameter changes, like Milankovitch's theory?

The 2013 data showed signs of a transit consistent with Bb's suggested orbital parameters, but it seemed to last slightly longer than expected, and the statistical validity of the signal disappeared when combined with the 2014 data.

It is a solar - like main - sequence star with a similar yellowish colour, [31] whose stellar classification is spectral type G2 V. From the determined mutual orbital parameters, Alpha Centauri A is about 10 percent more massive than the Sun, with a radius about 22 percent larger.

«Our predictions indicate that the presence (or absence) of tidally driven fractures could be used to constrain Charon's internal structure and orbital parameters at the time of fracture formation.

«This excess of objects with unexpected orbital parameters makes us believe that some invisible forces are altering the distribution of the orbital elements of the ETNO and we consider that the most probable explanation is that other unknown planets exist beyond Neptune and Pluto,» explains Carlos de la Fuente Marcos, scientist at the UCM and co-author of the study.

When forced by 6 ka orbital parameters, state - of - the - art coupled climate models and EMICs capture reconstructed regional temperature and precipitation changes (Sections 6.5.1.4 and 6.5.1.5), whereas simulated global mean temperatures remain essentially unchanged (< 0.4 °C; Masson - Delmotte et al., 2005b), just as expected from the seasonality of the orbital forcing (see Box 6.1).

The response of that model to volcanic forcings, the last ice age, changes in orbital parameters etc. are all «out - of - sample» tests that are not fixed by adjusting parameters.

Plus, the solar insolation is always changing, not just the sun spot cycle but also orbital parameters.

However, climates at high latitude are known to be very sensitive to orbital parameters affecting insolation (Ravelo et al., 2004), and thus proxy estimates with uncertain age constraints are not directly comparable to model simulations that typically span hundreds of years.

This clustering of orbital parameters of the most distant KBOs suggested a large, planetary size body shepherding their orbits.

The current understanding of those cycles is that changes in orbital parameters (the Milankovich and other cycles) caused greater amounts of summer sunlight to fall in the northern hemisphere.

The difference in greenhouse gas concentration combined with significantly different orbital parameters and seasonal insolation may limit the validity of using the Last Interglacial as an analogue for predicted future changes to the climate system.

«Glacial and interglacial cycles are driven by the sun and Earth orbital parameters that impact solar insolation (intensity of the sun's rays) as well as by changes in the continental ice sheets and greenhouse gas concentrations.»

The now hyper - arid Sahara desert was characterized by a lush extent of grass and consequently reduced dust emission due to changes in Earth's orbital parameters.

Now it's been confirmed after more observations that reduced the number of errors in the orbital parameters.

Kane and his colleagues were able to confirm its extreme eccentricity and the rest of its orbital parameters as part of the Transit Ephemeris Refinement and Monitoring Survey (TERMS), a project led by Kane to detect extrasolar planets as they pass in front of their stars.

«Human influence is so dominant now,» Baker asserts, «that whatever is going to go on in the tropics has much less to do with sea surface temperatures and the earth's orbital parameters and much more to do with deforestation, increasing atmospheric carbon dioxide and global warming.»

Transits, though subtle and brief, carry a great deal of information about a planet: the amount of dimming conveys the diameter of the planet, and the frequency of transits provides the planet's orbital parameters.

«The essential nature of exoplanets is still something of a mystery to us: despite finding nearly 2000 exoplanets we haven't yet found any discernible pattern linking the presence, size or orbital parameters of a planet to what its parent star is like,» said Tinetti.

Through ACCESS, we are compiling a library of exoplanet transmission spectra, which will ultimately enable us and the wider exoplanet atmosphere community to study trends in the atmospheric properties of exoplanets as they relate to the exoplanets» masses, radii, and orbital parameters.

By comparing dynamical simulations with non-interacting Keplerian orbits, we concluded that neglecting interactions between planets may lead to systematic errors that could hamper the precision in the orbital parameters when the dataset spans several years.

We developed a MC simulation tool to predict the outcome of a given survey, depending on the shape of the orbital parameter distributions.

Note that the shaded vertical bars are based on the ice core age model (EPICA community members, 2004), and that the marine record is plotted on its original time scale based on tuning to the orbital parameters (Lisiecki and Raymo, 2005).

«What we show in our paper is that we escaped the glacial inception naturally, thanks to a proper combination of Earth's orbital parameters and natural CO2 concentration.»

While Milankovitch forcing predicts that cyclic changes in the Earth's orbital parameters can be expressed in the glaciation record, additional explanations are necessary to explain which cycles are observed to be most important in the timing of glacial — interglacial periods.

Regular variation in the Earth's orbital parameters has been identified as the pacemaker of climate change on the glacial to interglacial time scale (see Berger, 1988 for a review).

«A planet is a sub-stellar mass body that has never undergone nuclear fusion and that has sufficient self - gravitation to assume a spheroidal shape adequately described by a triaxial ellipsoid regardless of its orbital parameters,» the proposal said.

The two objects [Sedna and 2012 VP113] have similar values for one of their orbital parameters: the angle [w] between the point of perihelion and where the orbit crosses the plane of the Solar System [from south to north].

Other ideas have been suggested, but current thinking is still that it is related to the orbital parameters in some way.
