  The breakup of liquid threads into smaller droplets is a fundamental problem
in fluid dynamics. In this study, we estimate the characteristic wavelength of
the breakup process by means of many-body dissipative particle dynamics. This
wavelength shows a power-law dependence on the Ohnesorge number in line with
results from stability analysis. We also discover that the number of satellite
droplets exhibits a power-law decay with exponent $0.72 \pm 0.04$ in the
product of the Ohnesorge and thermal capillary numbers, while the overall size
of main droplets is larger than that based on the characteristic wavelength
thanks to the asynchronous breakup of the thread. Finally, we show that the
formation of satellite droplets is the result of the advection of pinching
points towards the main droplets in a remaining thinning neck, when the
velocity gradient of the fluid exhibits two symmetric maxima.
