The following videos depict one of the flyby simulations presented in On the rise times in FU Orionis events(Borchert et al., 2022), showing temperature and column density evolutions.
Side view temperature of a stellar flyby with a periastron distance of 20 AU. The bottom right shows the accretion rates of both stars. Turn the audio on to also hear an audible representation of the mass accretion rates added together.
Face on temperature of a stellar flyby with a periastron distance of 20 AU. The bottom right shows the accretion rates of both stars.
Side view column density of a stellar flyby with a periastron distance of 20 AU. The bottom right shows the accretion rates of both stars.
