Galactic cosmic rays (GCRs) are energetic particles traveling across the Galaxy as high-energy beams, and are a unique probe to explore the astrophysical particle accelerators and the interstellar ...

IN a recent communication Deeming and Walker 1 have found that for hot stars there is a significant positive correlation between their helium line strengths and their apparent rotational velocities.

The latest observations from Low Earth Orbit with the International Space Station provide further evidence of spectral hardening and softening of cosmic ray particles. The CALorimetric Electron ...

Using the Subaru Telescope, researchers at the Special Astrophysical Observatory in Russia and Kyoto University in Japan have found evidence that enigmatic objects in nearby galaxies — called ...

A research team from the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences has detected radio recombination lines (RRLs) of ions heavier than helium for the first time, using ...

“The abundance of various elements in our sun, or in any other star, is estimated from their absorption spectral lines. Since helium does not produce any observable spectral lines from the visible ...

THE spectra of helium and hydrogen have acquired considerable importance in view of the recent experimental researches of Prof. Fowler and the theoretical investigations of Dr. Bohr. Before the ...

For the first time, and contrary to popular belief, scientists measured the vibrational structure of hydrogen and helium atoms by X-rays. The results disprove the misconception that it’s impossible to ...
