Science and Motivation

This workshop aims to provide an opportunity to exchange views and share information about the current status of observations and theoretical research on a wide range of aspects concerning the formation of astronomical objects.

Moreover, it also serves as interim report by students in our research group who are working on dissertations.

In view of the recent COVID-19 situation, we will hold the event online this year. We will let you know how to connect to the workshop once you have registered.

You are welcome to upload your slides in advance. This will be helpful for everyone when following the talks online.
