Sentences with phrase «hydrogen emission»

Type I supernovae happen in close binary systems and do not show strong hydrogen emission lines.

Co-author Dr Luca Cortese said detecting atomic hydrogen emission from distant galaxies is very challenging.

Hydrogen emission from EGSY8p7 may indicate it is the first known example of an early generation of young galaxies emitting unusually strong radiation.

Type II supernovae happen in single star systems (or at least far enough away from any companion star to retain their hydrogen outer layers) and have strong hydrogen emission lines.

Type Ib and Ic supernovae result from the collapse of a massive star's core whose outer hydrogen layers have been transfered to a companion star or blown off from strong winds which is why they do not show hydrogen emission lines.

«Astronomers detect atomic hydrogen emission in galaxies at record breaking distances.»

The FORTIS spectrographic element splits the light captured by the telescope into segments of varying wavelength intensity, which help scientists discern hydrogen emission and absorption.

We speculate that this truncation of the outer disk may be the signpost of a developing gap due to the effects of a growing protoplanet; the gap is still presumably evolving because material still resides in it, as indicated by the silicate emission, the molecular hydrogen emission, and by the continued accretion onto the central star (albeit at a much lower rate than typical of younger T Tauri stars).

To see the pink hydrogen emission nebulae, the gas there is excited by extremely hot uV emitting type O and B stars which raise the hydrogen above the ground state so it can emit visible light.

Spectroscopic observations revealed that the planet is only about three to four times the size of the star — but its hydrogen emissions are almost as bright as the emission emanating from the star.

MAUNAKEA, Hawaii — A team of astrophysicists using the W. M. Keck Observatory in Hawaii has successfully measured the farthest galaxy ever recorded and more interestingly, captured its hydrogen emission as seen when the Universe was less than 600 million years old.

Light emitted by oxygen is shown as blue, hydrogen emission is shown as green, and nitrogen emission as red light.
