... ALMA has the potential to detect and resolve CO rotational line emission in debris disks, potentially providing key information to determine its provenance. " " (e.g. LTE, CO/H2 abundance ratio) do not necessarily apply in low gas density environments such as debris disks, and can lead to orders of magnitude errors in CO mass estimations. The 3 upper limit on the total CO mass for the Fomalhaut system is of 5.8 x 10-5 Mearth. ... Different colours represent different gas kinetic temperatures. ...

... The lamps used for flat fields have an uneven spectral emissivity. ... Therefore a direct flat-fielding, i.e. , division by the original dark subtracted flat-field, produces spectra which are artificially enhanced in some parts and depressed in others. ... This command first averages the original image along the slit (assumed to be along the Y-axis) and fits the resulting one-dimensional image by a polynomial of specified degree. ...

... Stars . ... Located 22 000 light-years away from the Sun, this is the closest region of this kind known in our galaxy. ... Look out at the sky tonight and you will see how stars vary in brightness. ... Although the vast majority of stars we see in the night sky are brighter than the Sun, actually small and dim M type stars called red dwarfs (stars physically smaller than our Sun are classed as dwarf stars) seem to be the most common stars in space, at least in our part of the Milky Way galaxy. ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...

Starting with the study of the propagation of radio waves in the ionosphere, a wide variety of plasma waves was identified, in general spreading differently along magnetic field lines than perpendicular to them. ... From fusion research, space scientists borrowed the theory of plasma trapping by a magnetic field, and from ionospheric physics, the theory of plasma waves. ...

... A three-cell test section roughly representative of the primary mirror was provided for this test by the Steward Mirror Lab. ... Additionally, the tests are intended to determine relative airflow vs. pressure drop characteristics for each of the air flow patterns so the results can be evaluated both as a function of flow rate and of pressure drop along the flow path. ... The bottom (top as installed) was cut out so it could close the chamber for heating and be removed for the cooling tests. ...
