Internal dynamics and dynamical friction effects in the dwarf spheroidal galaxy in Fornax

Understand

In the Fornax dwarf spheroidal galaxy the globular clusters are distributed widely, without any significant central concentration.

• Oh et al.
• pointed out that such a distribution is paradoxical: dynamical friction effects estimated using single-component King models would have forced the globular clusters to spiral down to the center of the galaxy well within a Hubble time.
• This paper is devoted to a discussion of this paradox.
