Sentences with phrase «higher surface gravity»

However, the distribution of material from the dayside to the nightside of a planet is only likely to occur on worlds with a high surface gravity.

I recall us in our pallor at the stand - offish kibbutz on its narrow shelf of shore past the Qumran scroll mines, how they had fresh water hoses afloat on the surface to wash our mouths and eyes if the clear Mars - gravity water got into them, as we drifted high as triremes.
Using ultraprecise atomic clocks, scientists proved that for every one foot higher you move above the Earth's surface, time speeds up by a factor of 0.00000000000000004 due to the slight decrease in the force of gravity — just as general relativity would predict.
It found that small particles existing at 150 km or higher above Earth's surface could be knocked beyond the limit of Earth's gravity by space dust and eventually reach other planets.
We argue that KELT - 18b's high temperature and low surface gravity, which yield an estimated ~ 600 km atmospheric scale height, combined with its hot, bright host make it an excellent candidate for observations aimed at atmospheric characterization.
From high - resolution spectroscopy of the star, we find a stellar effective temperature Teff = 5541 \ pm 60 K, a metallicity [Fe / H] = -0.13 \ pm 0.06, and a surface gravity log (g) = 4.59 \ pm 0.10.
By using advanced high contrast imagers, it is possible to conduct high resolution spectroscopy on imageable exoplanets, after the star light is first suppress... ▽ More Spectroscopic observations are extremely important for determining the composition, structure, and surface gravity of exoplanetary atmospheres.
Here we present a sample of 10,341 likely red - clump stars (RC) from the first two years of APOGEE operations, selected based on their position in color - metallicity - surface - gravity - effective - temperature space using a new method calibrated using stellar - evolution models and high - quality asteroseismology data.
In this paper, we aim to (1) re-determine the chemical abundances of the APOGEE+K epler stellar sample (APOKASC) with an independent procedure, line list and line selection, and high quality surface gravity information from astroseismology, and (2) extend the abundance catalogue by including abundances that are not currently reported in the most recent APOGEE release (DR12).
Key features of this system include a high - pressure containment vessel immersed in a large pool of water and a passive emergency core cooling system that relies only on gravity - driven convection of the coolant and conduction of heat to the containment vessel surface.
While the slightly firmer suspension helps to counteract the dynamic effects of a higher center of gravity, the modifications to the chassis enable QX30 to remain comfortable at all speeds and over a variety of road surfaces.
Momentum is conserved but gravity is reversed, letting you fling yourself high into the air or deep beneath the surface.

Bob, Your point about gravity is quite right, which is why at the surface, the temperature is higher than the stratosphere.
So it's all gases at greatest density will be doing the same thing around the planet at the same time (*) and as these change with differences in density in the play between gravity and pressure and kinetic and potential from greatest near the surface to more rarified, less dense and absent any kinetic to write home about the higher one goes, then, energy conservation intact, the hotter will rise and cool because losing kinetic energy means losing temperature, thus cooling they which began with the closest in density and kinetic energy as a sort of band of brothers near the surface will rise and cool at the same time whereupon they'll all come down together colder but wiser that great heights don't make for more comfort and giving up their heat will sink displacing the hotter now in their place when they first went travelling.
So, without any external heat source and none from the planet all that's in play here is the heat this chilled out band of brothers gains on the way down, heavier and sinking gaining kinetic energy and therefore temperature the denser they get until finally at the surface becoming too hot they expand and rise slipping out of their restricting gravity and rude neighbours bumping into them they get themselves some space and cool off, then coming back off their high when they realise just how cold and lonely they are, getting nostalgic again for their noisy neighbours who won't stick to their side of the road, forgetting, we do forget just how horrible horrible past experiences were, that they'll just get all hot and bothered again.
This higher temperature on earth's surface is because of gravity potential energy field.
The surface is indeed warmer than the mean radiating temperature, but the higher temperatures are maintained by the effect of gravity which establishes the so - called «lapse rate» as an equilibrium state.
The gases under high gravity's pressure closer to the surface are being condensed, bringing them closer together there are more of them so their combined weights under gravity are heavier than gases further away from the surface which have expanded becoming lighter because there are less of them taking up the same room, there are fewer of them so weigh down less heavily on us.
The pressure of gravity here is its pulling power on the mass of the real gas molecule, the gases closer to the surface are under higher pressure than the gases further away from the surface.
