[P-AE17] Exoplanets

Thu. May 26, 2022 3:30 PM - 5:00 PM 105 (International Conference Hall, Makuhari Messe)

convener:Masahiro Ikoma(Division of Science, National Astronomical Observatory of Japan), convener:Norio Narita(The University of Tokyo), Yuka Fujii(National Astronomical Observatory of Japan), Chairperson:Norio Narita(The University of Tokyo)

Exoplanetary science, which began with the discovery of a hot Jupiter in 1995, reached a significant turning point by the detection of countless super-Earths by the Kepler space telescope. In 2018, the new space telescope TESS was launched to conduct an extensive survey of exoplanets orbiting nearby bright stars, opening a new era of characterization of exoplanet atmospheres. Moreover, recent observations have identified a growing number of terrestrial planets in the so-called habitable zone. While exoplanets have been targeted mainly for astronomy until recently, it would be fair to say that Earth and planetary science is finally becoming a research field to make a central contribution. This session aims at allowing participants to share their research results and new ideas regarding exoplanets and also inform the current status of their projects. Exoplanet science is a growing, interdisciplinary research field. We welcome participants from various fields.
