Comparing radial migration in dark matter and MOND regimes

Open Access

Table 7

Ratio of the MOND and DM fractions of stars with significant changes of the guiding radius.

Ω_sp	A_sp	$\frac{\| d R_{ɡ, MOND} \| > 1.5 kpc}{\| d R_{ɡ, DM} \| > 1.5 kpc}$ ${{\left\| {{\rm{d}}{R_{,{\rm{MOND}}}}} \right\| > 1.5\,{\rm{kpc}}} \over {\left\| {{\rm{d}}{R_{,{\rm{DM}}}}} \right\| > 1.5\,{\rm{kpc}}}}$
19	1000	5.45
	850	2.56

25	1000	3.94
	1200	4.10

31	1000	1.88

Notes. A maximum change in the guiding radius larger than 1.5 kpc during the time interval 2–6 Gyr was considered. The units of Ω_sp and A_sp are km s⁻¹ kpc⁻¹ and km² s⁻² kpc⁻¹, respectively.
