Radio Exploration of Planetary Habitability: Conference Summary
Radio Exploration of Planetary Habitability was the fifth in the series of American Astronomical Society's Topical Conference Series. Notable aspects of the conference included the interdisciplinary nature of both the topics and the intellectual breadth of the participants, the diversity of approaches to studying this topic presented by recent discoveries and of the participants themselves, the expanding meaning of the topic of "star-planet interactions," and the expectation of an increasingly statistical approach to the topic. Potential areas of future research include the actual extent to which planetary magnetic fields shield planetary atmospheres; the planetary dynamo process itself, particularly once multiple extrasolar planetary magnetic fields are confirmed; and "planet-star interactions." A major major topic of the conference concerned observational opportunities, highlighted by a number of new or upcoming, specialized observatories to observe exoplanets especially at radio wavelengths. This article summarizes these main points of the conference and expands briefly upon these potential avenues for future investigation. A future meeting on this topic, given the variety of data sets being generated over the next few years, is warranted.
