This heavy element upwells from a star's core (where it is produced) to the surface (near where it is observed) in a phase called the third dredge - up, when material in deep helium - burning layers is brought to the surface through convection.
That effect was first demonstrated during a total solar eclipse in 1919, when the positions of stars near the Sun were observed to be slightly shifted from their usual positions — an effect due to the pull of the Sun's gravity as the stars» light passed close to the Sun.
Besides these remote organizations, investigators have observed what appear to be groups of high - velocity stars near the Sun.

«We're accustomed to seeing how our Sun appears in visible light, but that can only tell us so much about the dynamic surface and energetic atmosphere of our nearest star,» said Tim Bastian, an astronomer with the National Radio Astronomy Observatory in Charlottesville, Va. «To fully understand the Sun, we need to study it across the entire electromagnetic spectrum, including the millimeter and submillimeter portion that ALMA can observe.»
