Collaboration has obtained a high-precision cosmic-ray boron spectrum in the energy range of 10 GeV/n–8 TeV/n, and discovered ...

In particular, the presence and strength of Ge II lines helped distinguish it from other cool EHes and cemented its position as a new chemical outlier. Figures from the study display comparative ...

"The new brown dwarfs are the least massive known brown dwarfs. They place a new constraint on the lowest mass at which brown dwarfs exist." ...

Since helium does not produce any observable spectral lines from the visible surface, or the photosphere of the sun, its abundance has usually been estimated through indirect means,” the ...

The Challenge of Measuring Helium in the Photosphere Helium, the second most abundant element in the Sun after Hydrogen, poses a unique observational challenge. Unlike many elements, Helium does not ...

They used a refined approach, analyzing the spectral features of Magnesium and Carbon, including their hydrogenated molecular forms (MgH, CH, and C₂). They successfully constrained the Sun’s helium ...

Lockyer shares the honour of discovering helium with Frenchman Pierre Janssen, who independently spotted the rogue spectral line in 1868. The pair coincidentally filed their paperwork on the same ...

By the mid-1800s, researchers found that light from heated gaseous elements in laboratories produced opposite spectral patterns—mostly empty regions separated by bright lines of color.

Guntur, spectral lines, and the discovery of helium Did you know that helium is the first alien element, so as to say? This means that its existence elsewhere was discerned much before it was ...
