Solar Radioastronomy with Solar Orbiter and Parker Solar Probe : capabilities and expectations.

Milan Maksimovic, CNRS & LESIA, Paris Observatory France

We will review some of the open questions in Solar Radioastronomy and the way they can be addressed by the RPW and FIELDS instruments on the Solar Orbiter and Parker Solar Probe missions. Among those questions the study of the connectivity between the solar corona and the inner Heliosphere are of prime importance. We will review the technical capabilities in the radio domain for both of the of the two instruments which allow observations up to 16 MHz for RPW and 20 MHz for FIELDS. We discuss also about the importance of making observations from two vantage points in the heliosphere and as close as 10 Solar radii from the Sun.
