Sentences with phrase «on spectral lines»

[16] This two - dimensional (temperature and luminosity) classification scheme is based on spectral lines sensitive to stellar temperature and surface gravity, which is related to luminosity (whilst the Harvard classification is based on just surface temperature).

Radiating the antihydrogen atoms with microwaves allowed the physicists to determine its light fingerprint in a rather indirect way, using specific changes in the antihydrogen that caused them to eject from the magnetic bottle to fine tune estimates on its spectral lines.

These studies which are based on spectral line observations of molecular gas suggest a new method of potentially discovering inactive isolated black holes that are undetected by traditional method such as X-ray observations.

Not exact matches

Based on the wavelengths of spectral lines emitted by the luminous gas surrounding the black hole, the object is traveling at a speed of about 7.5 million kilometers per hour — a rate that would carry it from Earth to the moon in about 3 minutes.

In a breakthrough, a group of researchers at the National Institute of Standards and Technology developed an on - silicon - chip laser source with outputs that consist of precisely defined and equally spaced optical lines within the mid-infrared spectral region.

Yet so far, star formation historians have mostly relied on other indicators to write their histories: light at a particular frequency that is typically emitted when giant clouds collapse, heating up in the process and radiating away that heat in the form of specific spectral lines.

They plan to measure other spectral lines and even test the pull of gravity on antihydrogen — to see if it is pulled down or pushed up.

The Argus millimeter - wave camera on the GBT produces data cubes of the emission from spectral lines with high spectral and spatial resolution.

Infrared light, on the other hand, traces dust in a galaxy, and emission lines that are detected in spectral lines trace the gas clouds.

Previously classed as spectral type M4.5 e (with emission lines), the object was observed to be four times brighter than would be expected for a dim red dwarf of that type based on a revised parallax measurement of its distance from the Solar System (Ken Croswell, Science@Now, September 6, 2011).

The dynamics of solar processes can be captured on shorter time scales, and the improved light - gathering capacity of the new telescopes allows us to extract more information from spectral lines with higher fidelity and accuracy, especially with respect to magnetic field measurements.

HARPS has been enormously successful at detecting exoplanets using the radial velocity method, or measuring the gravitational tugs on stars by their planets by watching the stars» spectral lines «wobble» back and forth due to the Doppler effect.

Enigmatic and organic, the drawings are delicately realised in graphite and ink: Osiris is shown sitting on a watery black throne; a blindfolded figure with multiple top hats takes spectral shape against a network of fine lines in a reference to the late performance artist James Lee Byars and his trademark costume.

The solar spectrum of the sun consists of a roughly black body like thermal continuum spectrum, peaking at around 0.5 microns wavelength (plotted on wavelength scale; not wave number), and overlaid with the Fraunhoffer lines of either bright atomic spectral lines, due to elements in the sun, or dark atomic absorption lines, due to absorption of elements in the solar outer atmosphere.

If one were to take the model and plot a curve of emission versus wavelength rather than simply summing up the values (integrating over wavelength), it would show a spectral curve of a black body at 288.2 k with the absorption lines of the atmosphere dipping down to the point where there is a spectral curve for a lower temperature at which there is emission going on in the wavelength bands associated with ghg absorption.

Furthermore, on 22 April 1981 Mr. Gilbert Plass wrote that, whilst on the faculty at Johns Hopkins University during that period (1946 - 1955), he became interested in infrared spectroscopy — specifically in regards to pressure broadening of spectral lines (in explaining radiative transfer in the earth's atmosphere)-- and collaborated with Mr. John Strong in the above article because the need for [quote] «mathematical methods» [endquote], applicable to water, carbon dioxide and ozone, was obvious to him then.

Sometime in the» 90's some college students were examining spectral lines (Bright lines made by glowing chemicals, when the light from those chemicals are passed through a prism... chemicals on the sun's surface tend to glow) from sunspots on the sun.

I understand that there is not a linear relationship between CO2 concentration and Earth's average temperature; that as CO2 concentration increases, the marginal effect on temperature decreases due to saturation of spectral lines.

No need to build up a narrative that relies on the IR line spectral properties of CO2 which compose 0.03 % of the atmosphere in the so called greenhouse effect.

On the other hand, once water is present, its IR spectral lines overlap with those of CO2 and make CO2 less potent a greenhouse gas — for the same reason why the temperature dependence on CO2 concentration becomes logarithmic: the previous molecules have already done much of the effect, anywaOn the other hand, once water is present, its IR spectral lines overlap with those of CO2 and make CO2 less potent a greenhouse gas — for the same reason why the temperature dependence on CO2 concentration becomes logarithmic: the previous molecules have already done much of the effect, anywaon CO2 concentration becomes logarithmic: the previous molecules have already done much of the effect, anyway.
