Astrochemistry

Course
2024-2025

Admission requirements

Bachelor in Astronomy or equivalent and in particular knowledge of radiative processes is required.

Description

The space between the stars is not empty but filled with a very dilute gas with extremely low densities and temperatures, providing a unique laboratory with conditions not normally encountered on Earth. A surprisingly rich chemistry occurs in these so-called interstellar clouds, as evidenced by the discovery of more than 200 different molecules. Some of these species were found in space before they were identified in a laboratory on Earth. How are these molecules formed? Where are they found and how do astronomers identify them? How do their abundances differ from place to place and what does this tell us about the structure of the region? How do the abundances evolve from cold clouds to planet-forming disks, where they can form the basis for prebiotic species?

The outline of the course is as follows:

  • Basic principles of gas-phase and gas-grain chemical reactions

  • Chemistry in the early Universe

  • Chemistry in diffuse and translucent clouds, and in photon-dominated regions

  • Chemistry in shocks

  • Evolution of molecular abundances from dark pre-stellar cores to star-forming regions

  • Chemistry in protoplanetary disks and links with comets

Course objectives

The student will gain relevant background information that will enable him/her to follow the current literature on Astrochemistry and to do research in this field. The student will also acquire hands-on experience with running molecular excitation and chemical network codes, and make predictions for ALMA.

Soft skills

In this course, students will be trained in the following behaviour-oriented skills:

  • Structured thinking (structure, modulated thinking, computational thinking, programming)

  • Verbal communication (presenting, speaking, listening)

  • Critical thinking (asking questions, check assumptions)

  • Creative thinking (resourcefulness, curiosity, thinking out of the box)

Timetable

See Astronomy master schedule

In MyTimetable, you can find all course and programme schedules, allowing you to create your personal timetable. Activities for which you have enrolled via MyStudyMap will automatically appear in your timetable.

Additionally, you can easily link MyTimetable to a calendar app on your phone, and schedule changes will be automatically updated in your calendar. You can also choose to receive email notifications about schedule changes. You can enable notifications in Settings after logging in.

Questions? Watch the video, read the instructions, or contact the ISSC helpdesk.

Note: Joint Degree students from Leiden/Delft need to combine information from both the Leiden and Delft MyTimetables to see a complete schedule. This video explains how to do it.

Mode of instruction

  • Lectures

  • Exercise classes

Assessment method

  • In-class assessment (30%)

  • Written exam (70%)

Both assessments have to be passed in order to pass the course.

Reading list

  • Handouts of lecture notes, both on paper and electronically on website

Registration

As a student, you are responsible for enrolling on time through MyStudyMap.

In this short video, you can see step-by-step how to enrol for courses in MyStudyMap.
Extensive information about the operation of MyStudyMap can be found here.

There are two enrolment periods per year:

  • Enrolment for the fall opens in July

  • Enrolment for the spring opens in December

See this page for more information about deadlines and enrolling for courses and exams.

Note:

  • It is mandatory to enrol for all activities of a course that you are going to follow.

  • Your enrolment is only complete when you submit your course planning in the ‘Ready for enrolment’ tab by clicking ‘Send’.

  • Not being enrolled for an exam/resit means that you are not allowed to participate in the exam/resit.

Remarks

Software
Starting from the 2024/2025 academic year, the Faculty of Science will use the software distribution platform Academic Software. Through this platform, you can access the software needed for specific courses in your studies. For some software, your laptop must meet certain system requirements, which will be specified with the software. It is important to install the software before the start of the course. More information about the laptop requirements can be found on the student website.
