The Astrobiology and Planetary Exploration (APEX) seminars resume this term (Thursday 17 January, 13:00, Garwood Lecture Theatre, UCL South Wing) with a special invited talk by Dr Michele Bannister from Queen’s University Belfast:

  • Dr Michele Bannister (QUB) - First arrival from afar: Interstellar planetesimal 1I/'Oumuamua and the past and present of planetary systems

Abstract: The small bodies of planetary systems record how their systems formed and evolved. Major observational surveys are providing new insight into the intricate, complex dynamical structure of the populations that exist in the Solar System, with hints at new, barely-seen populations. Adding colour measurements of their surface compositions is making it possible to piece together the original structure of our protoplanetary disk. Observations of the first interstellar object 1I/`Oumuamua show this visiting planetesimal has many curious properties, with kinship to the tiny worlds in our own system. Its 10^26 cousins wandering the Galaxy hint at an overarching cycle of planetesimal formation and scattering over billions of years.

Everyone interested in these topics is welcome to attend.
