    • 1970, Alfred Gordon Gaydon, Flames; their structure, radiation and temperature, page 204:
      There is good evidence that with burning oil sprays the larger droplets may crack to carbon, sometimes forming xenospheres which pass through the flame front.
    • 1988, Ronald J. Adrian, Laser Anemometry in Fluid Mechanics III:
      In the region of the spray cone rather large vaporizing or burning oil droplets up to 100 rim, or their residuals like xenospheres, will be found.
