The evolution of comet composition at large heliocentric distances

该项目的目的是研究彗星的表观组成在大的日心距离上如何变化，利用光学光谱学确定彗星气体中的分子产生率。彗星释放的气体或多或少取决于它们与太阳的距离，但在气体中观察到的不同分子的相对丰度也不同。因此，确定彗星表观成分的变化趋势对于了解彗星核的成分至关重要。我还在从事一项小行星活动探测项目，旨在探测主带小行星的彗星活动，以期发现新的主带彗星。

This project aims to study how the apparent composition of comets varies at large heliocentric distances, using optical spectroscopy to determine molecular production rates in cometary gases. Comets release more or less gas depending on their distance to the Sun, but the relative abundances of the different molecules observed in the gas varies as well. Therefore, characterising the trends that govern the apparent composition of comets is essential to understand the composition of their nuclei.I am also working on an asteroid activity detection project, aiming to detect cometary activity in Main Belt Asteroids in the hope of finding new Main Belt comets.
