Description
In the Astronomy Lab and Observing Project you will learn how to prepare and analyse astronomical observations with a professional telescope.
The scientific question will be conceived by you working in a group and will teach you how to work as a scientist.
The course consists of three parts. Each part is introduced in one or more lectures and carried out with the supervision of assistants during practical classes using computers running Linux. The first part introduces the students to photometry of stellar sources using both synthetic and aperture photometry with special attention paid to practical error analysis. The second part focuses on the fitting of models to observational data while the third part which runs parallel throughout the whole course, focuses on the definition and analysis of observations with a professional telescope and is carried out in groups of 3-6 students.
The course is defined by two substantial problem sets covering part 1 and part 2, while the observing project provides substantial freedom to the students.
The following themes are covered:
Telescope proposals, technical and scientific justifications.
Astronomical software (review) – ds9, topcat and python
Synthetic photometry
Matching of black body models to photometry
Aperture photometry
Error analysis for CCD photometry
Radial velocity modelling for exo-planets
Weighted chi square fitting
Statistical testing (type I and type II errors)
The chi square test
Markov Chain Monte Carlo
Scientific report writing
Course objectives
At the end of this course you will know how to prepare your own astronomical observations with a professional telescope and evaluate the results thereof.
After this course, you are able to:
Prepare and present in writing a science case for astronomical observations on a topic chosen by the group.
Design astronomical observations with a professional telescope.
Analyse and present the results of the astronomical observations.
Apply the techniques of synthetic photometry to spectra of celestial objects.
Analyse images of stellar sources and carry out aperture photometry on this, including practical error analysis.
Combine the knowledge of synthetic photometry with aperture photometry to analyse the energy distribution of stellar sources.
Formulate a model for planetary motion and fit this to observational data including observational uncertainties.
Apply Markov-Chain Monte Carlo techniques to observational data and analyse the results thereof.
At the end of the course you will have been trained in the following behaviour-oriented skills:
Abstract thinking
Evaluate the scientific proposals of other groups
Ability to construct and analyse a scientific case in a group
Correctly explaining and analysing complex and non-intuitive concepts
Ability to present results clearly in writing both in the form of reports and a poster
Timetable
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.

Written report
Poster presentation
The course is divided in three parts that count equally. The first two parts of the course are done on the basis of an obligatory report and the observing project is evaluated on the basis of the quality of the observing proposal, the preparation and execution of observations at the telescope and the final presentation of results in the form of a poster. The final grade is the average of the grade of the three sub-components to the course.
Reading list
There is no textbook associated with the course. The necessary background material will be made available during the course.
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.

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.
