Speed(top) and distance (bottom) of ejected particles from Vega. The trajectory calculations were made using β = 2. Uncertainties within β do not influence the dust trajectory. The particles are released from a circular orbit with radius = 0.1 AU and inclination of 5°. The top figure shows the speed of a single charged particle with charge-to-mass ratio 10⁻⁵ q_e /m_p. The bottom figure shows the distance from Vega. The orbits of the particles with a charge-to-mass ratio of at least 1 × 10⁻⁶ q_e/m_p are overlapping, as in Fig. 1.
