Solar and Extra-solar Systems

At ASIAA, there is a growing community of planetary scientists who are involved in a wide range of research topics.

In our own Solar System, the Taiwanese-American Occultation Survey (TAOS) aims to measure the size distribution of objects in the Kuiper Belt, Scattered Disc and Inner Oort Cloud. A successor survey, TAOS II, is currently under construction at San Pedro Mártir Observatory in Baja California, Mexico. This new survey will be more than one hundred times as powerful as its predecessor. In addition to the occultation surveys, the group is involved with the proposed Hyper Suprime Cam (HSC) Survey using the Subaru telescope. The proposed survey will cover up to 2000 square degrees down to a magnitude of g’=26.4. Finally, the group is discussing the possibility to join a successor to the Canada France Ecliptic Plane Survey (CFEPS) which will use the Canada France Hawaii Telescope (CFHT).

On the theoretical side our group is involved in several areas of research. The first of these concerns the origin and dynamical evolution of the Solar System, in particular the orbital structure of the Kuiper Belt, Scattered Disc and Oort cloud. This work ties in directly with the TAOS and TAOS II projects. In addition, work is being done on the evolution of the terrestrial and giant planets at the time of the Late Heavy Bombardment of the terrestrial planets.

We are also involved in work studying active asteroids (which include main-belt comets and disrupted asteroids) with initiatives including searching for active objects in various data sets, such as the HSC, Pan-STARRS, and Palomar Transient Factory surveys, using numerical simulations to study their dynamical behavior, and performing physical characterization studies of individual objects. The ice content inferred for MBCs makes them extremely interesting targets in terms of astrobiology, while studying the disruptive processes (rotational break-ups and impacts) that cause activity in disrupted asteroids will give us insights into how these processes shape small bodies in our solar system and give us clues as to their internal structure and composition.

Besides the Solar System, we are engaging in research work on exoplanets. Hot Jupiters are intensely illuminated, and tidally interact with their parent stars. Atmospheric circulation on a hot Jupiter driven by stellar irradiation is being investigated in terms of linear waves. Tidal interactions can dramatically change the interior structure of a young hot Jupiter and even destruct the planet in the T-Tauri star phase, which may explain the mass distribution of hot Jupiters observed today. Numerical simulations are being conducted to study the influence of a planet embedded in a protoplanetary disk to interpret the ALMA results in the near future.
