Interstellar Dust in the Solar System
The Ulysses spacecraft has been orbiting the Sun on a highly inclined ellipse almost perpendicular to the ecliptic plane (inclination 79◦, perihelion distance 1.3 AU, aphelion distance 5.4 AU) since it encountered Jupiter in 1992. The in-situ dust detector on board continuously measured interstellar dust grains with masses up to 10−13 kg, penetrating deep into the solar system. The flow directi...
متن کاملIcy Bodies in the New Solar System
This brief paper summarizes a “key general review” with the same title given at the IAU meeting in Rio de Janeiro. The intent of the review talk was to give a broad and well-illustrated overview of recent work on the icy middle and outer Solar system, in a style interesting for those astronomers whose gaze is otherwise drawn to more distant realms. The intent of this written review is the same.
متن کاملIs the Solar System Entering a Nearby Interstellar Cloud?
A model, based on different observations of the local interstellar medium, indicates the presence of a very close interstellar cloud in front of the Scorpius-Ophiuchus association (almost in the direction of the galactic center) approaching the solar system from a distance of about 0.03 pc at a velocity of about 15-20 km s. These observations are as follows: 1. The strong gradient of the hydrog...
متن کاملPrecursors to Interstellar Shocks of Solar Origin
On or about 2012 August 25, the Voyager 1 spacecraft crossed the heliopause into the nearby interstellar plasma. In the nearly three years that the spacecraft has been in interstellar space, three notable particle and field disturbances have been observed, each apparently associated with a shock wave propagating outward from the Sun. Here, we present a detailed analysis of the third and most im...
متن کاملThe Solar–Stellar Connection
The discovery that radio emission from stars is quite common and readily detectable was one of the unexpected advances produced by the Very Large Array [35,11]. This discovery could not be predicted based on what we know of the Sun’s radio emission, even though similar physical mechanisms are operating in stellar radio sources and so knowledge of the Sun’s emission is essential for understandin...
