Showcased at the center of this NASA/ESA Hubble Space Telescope image is an emission-line star known as IRAS 12196-6300.

Located just under 2,300 light-years from Earth, this star displays prominent emission lines, meaning that the star's light, dispersed into a spectrum, shows up as a rainbow of colors marked with a characteristic pattern of dark and bright lines. The characteristics of these lines, when compared to the "fingerprints" left by particular atoms and molecules, can be used to reveal IRAS 12196-6300's .

Under 10 million years old and not yet burning hydrogen at its core, unlike the sun, this star is still in its infancy. Further evidence of IRAS 12196-6300's youth is provided by the presence of . These hazy clouds, pictured floating above and below IRAS 12196-6300, are created when light from a star reflects off a high concentration of nearby dust, such as the dusty material still remaining from IRAS 12196-6300's formation.

Access to this article is changed (blurred) but it is evident that this is a white star. https://en.wikipe...#Class_F
"Their color is white."
White stars means: high temperature, high-speed rotation about an axis, a small radius (relation: mass / radius. Sun = 1), high surface gravity (4 and more CGS). Very fast rotation = the existence of the disk of gas and dust (in large majority of cases). Source http://www.svemir...tml#ring Article 4 and 3.
Readings of more complex elements was determined incorrectly, because they belong to the disk, not the star.
