12 N-body Study of Quasi-attractivity attractivity 12 AT & Sakagami (2004) in prep. Simulation setup Force calculation: GRAPE-6 # of particles : N=8,192 Softening length: ε = 1/Ν 4/N Perfectly reflecting Adiabatic wall G=M=re=1 =1 re
13 Initial Condition 13 A family of stellar models with cusped density profile: 1 ( r + ρ ( r) 3 η 1 + η r a) Tremaine et al. AJ 107 (1994) 634 f( ) =1.5 =2 =3 2 σ v(r) =1 =1 f ( ε) ( ε (3+ η)/2/( η 1) * ε) =1.5 =2 =3 a/re=0.5 = v 2 / 2 + Φ( r) a/re=0.5 r
14 Survey Results 14 Fitting failed Fitting to polytrope is good Final state is isothermal Previous work Quasi-attractive behaviors appear when 1< η & 0.3 < λ < 0.8
15 Cases with a/re=0.5 (1) =1 singular isothermal ( ) 15 =1.5 =3 ( )
16 Cases with a/re=0.5 (2) 16 =1 ( ) =1.5 =3
17 Physical Reason 17 Gravothermal expansion Local relaxation time Heat flows inward and flat core is formed. (Negative specific heat) Timescale becomes shorter for denser region. t r 3 σ v = G mρ ln Λ Power-law feature of f(ε) Polytropic behavior of ρ(r), σ v(r) are rapidly attained. =1.5 Degree of this behavior depends on the amount of heat-flow (a, η)
18 18 S BG = d 3 xd 3 v f(x, v) ln f(x, v) SBG (SBG, D)
19 19 Condition of quasi-attractive behavior in N-body system Power-law type distribution naturally arises when the sufficient amount of the inward heat-flow is supplied. For more rigorous argument, long-range attractivity (negative specific heat) A large N-body N simulation (N=16k~32k) with a more sophisticated N-body N code Analytic treatment based on the Fokker-Planck model (now in progress)
