Planetary Science

Marta Bryan explores what gas giants reveal about the formation and evolution of planetary systems. Their brightness and mass make them useful observational targets, and their gravitational influence can reshape the orbits and environments of smaller planets. The seminar combines several approaches. High-resolution spectroscopy of directly imaged planets measures rotation and obliquity, providing evidence about angular-momentum evolution. Radial-velocity searches for Jupiter-like companions to known inner planets probe how giant planets affect system architecture and inform the search for habitable worlds. The presentation also introduces observational work on planetary interiors and magnetic fields as further ways to test formation models.

AGU26 brings the Earth and space science community to San Francisco on 7–11 December 2026 for research presentations, scientific exchange, workshops and professional development. The programme spans Earth, planetary and space sciences, with opportunities for collaboration across disciplines. Registration and housing are currently open. The organizer lists 29 September as the late-breaking abstract deadline; the standard abstract round has already closed. The official event site provides registration, travel and programme updates for the meeting at the Moscone Center.

The EGU General Assembly 2027 will take place in Vienna and online from 4–9 April 2027, bringing together researchers across Earth, planetary and space sciences. The organizer’s current invitation is for scientific session proposals, with submissions due on 23 September 2026. This stage allows the community to shape the scientific programme. The official assembly website provides the session-proposal instructions and will carry subsequent abstract, attendance and registration information. The physical venue is the Austria Center Vienna.
