Far-infrared contribution to interstellar extinction from graphite whiskers

Letter to the Editor


A mass contribution of graphite whiskers as small as 0.1% to the population of interstellar grains could dramatically change their far-infrared extinction properties. With varying mass fractions of graphite whiskers, and for different size parameters, the infrared extinction could vary from a λ-2 dependence to λ0, consistent with the requirements of some astronomical observations.
