Interstellar dust is focused towards or defocused away from the ecliptic plane, depending on the phase of the solar magnetic cycle.
Summary
[edit]
| Description |
English: Interstellar dust particles enter the solar system from the left side of the image. Depending on the current phase of the solar magnetic cycle, they are focused (left panels) towards or defocused (right panels) away from the ecliptic plane (z = 0). This effect is stronger for particles with a higher charge-to-mass ratio, Q/m.
This image was generated from trajectory simulations with β = 1, i.e. with the effects of solar gravity and solar radiation pressure cancelling each other out. The simulations were started in 1999 for the focusing panels and in 2013 for the defocusing panels. Because it takes the particles multiple years to cross the solar system, those launched in 1999 (left) were mostly affected by the focusing effects in the years close to the solar minimum of 2008; and those launched in 2013 (right) were mostly affected by the defocusing effects in the years close the solar minimum of 2019. The yellow disc marks the position of the Sun, and the colouration denotes the particle speed with respect to the Sun. |
