    Notes: [Auszug] Because of the weak gravitational force of comets, neutral gas sublimated from the nucleus can escape freely from the collision-dominated inner coma. Neutral molecules in the comet are eventually ionized through processes2 such as photoioniz-ation by solar extreme-ultraviolet photons, charge ...

    Notes: Abstract Proton heating at stream interaction regions in the solar wind is investigated based on the solar wind data obtained by Suisei spacecraft between 0.68 and 1.01 AU from the Sun. The deflection angle of the solar wind flow in the ecliptic plane is used to identify the interaction region. In the solar wind flows coming from east of the Sun in low-speed streams and coming from west in high-speed streams, the radial gradient of proton temperature is flattened owing to heating in the interaction region. From comparison of the best-fitted power law dependence of proton temperature on the radial distance in the deflected flow with that in the non-deflected flow, it is suggested that heating in the interaction regions starts around 0.6–0.7 AU from the Sun.
