Sentences with phrase «surface density»

A recent paper by Jorge Dias (KTH) and several other researchers at SciLifeLab presents a novel method that circumvent previous limitations such as the need for high surface densities of nanoparticles to acquire -LSB-...]

The research findings are presented in the article Fukagawa et al. «Local Enhancement of Surface Density in the Protoplanetary Ring Surrounding HD 142527» published in the Publications of the Astronomical Society of Japan, on December 25th, 2013.

We will also explore a large parameter space, investigating how the final planetary system architecture and planetary properties are influenced by the planetesimal disk surface density and size.

The measurement of the projected surface density \ Sigma (r) is consistent with the shear measurements within the uncertainties, and has roughly 40 % of the signal - to - noise of the latter.

Moreover, the best - fit parameters derived from such a model suggest a very broad disk extending from few au up to few hundreds of au from the star with a nearly constant surface density which seems physically unlikely.

All models show surface density profiles increasing with distance from the star as inferred from observations.

We find a power - law correlation between the gas and SFR surface densities with significant differences in the power law index N between giant HII regions (N = 1.0) and spiral arms (N = 2.2) in M101.

Hence, a delicate balance must be achieved between irradiation fluence and surface density of the surfactant on the nanorods.

The study shows that the value of the surface density can be used to divide the composites into several groups.

GRAIL, which will map the moon's gravitational field to expose variations in its near - surface density, may be able to detect the residual effects of a long - lost moonlet pancaked across the lunar far side.

Using numerical simulations that run up to 100,000 orbits, we directly show that the migration of super-Earths, even systems of super-Earths, can be stalled, and they can open gaps that have surface densities 30 times lower than the background disk density.

Both M81 and M101 were observed with the Far - Infrared Surveyor (FIS) aboard AKARI in four far - infrared bands at 65, 90, 14... ▽ More We assess the relationships between the surface densities of the gas and star formation rate (SFR) within spiral arms of the nearby late - type spiral galaxies M81 and M101.

Surface density of the hard sources is almost consistent with that at high Galactic regions, thus most of the hard sources are considered to be Active Galactic Nuclei seen through the milky way.

Abstract: We assess the relationships between the surface densities of the gas and star formation rate (SFR) within spiral arms of the nearby late - type spiral galaxies M81 and M101.
