Astrochemical Models in the Protoplanetary Disk: Carbon and Nitrogen Isotope ratios
* Abstract
Isotopic ratios are a powerful tool for investigating the origin of solar system materials and for revealing the possible chemical link between the solar system and the interstellar medium. High spatial resolution and high sensitivity ALMA observations provide new information on isotopic ratios of carbon and nitrogen in the protoplanetary disks where planets form. Astrochemical model including updated networks enables us to study how the observed isotope ratios occur. In this talk, I will introduce the astrochemistry in the low mass star forming regions, especially the protoplanetary disk, and show how the observed carbon and nitrogen isotope ratios are reproduced.
