Astro-lab Winter term 2020/2021


Vorstellung Praktikum im Rahmen der ersten Vorlesung Astro-I am 5. November 2020



The preliminary list of participants.


Students on preregistration list for October 2021.


Update October 31: Du to the pandemic situation, we will not offer observations with the 70cm telescope throughout the month of November and probably even for the months to come afterwards. As soon as regulations and the situation allows, a DOODLE-list will be set up with potential observing dates and all registered participants will be informed about that opportunity. Observations with the 70 cm telescope are not mandatory, but voluntarily in WS 2020/2021 to successfully pass the astrolab.


Registration is open, but see notes below !!!


Notes on the astrolab to be held from March 8 - 19 2021:

  • Depending the panademic COVID-19 situation the astrolab will be held fully in presence, in a Hybrid mode with a number of tasks in presence and a number of tasks online, or completely online. This decision will be made by mid-February 2021.
  • At the moment we anticipate to offer it in Hybrid mode with 4 tasks in presence at the Landessternwarte Heidelberg and at the Philosophenweg 12 in Heidelberg as well as 6 tasks online as we have done during the astrolab in October 2020. Slides from an online presentation discussing the outline of the astrolab can be found here. More information about the astrolab in October 2020 can be found in a booklet circulated with the confirmation of participation here.
  • The E-mail with the confirmation of participation will also be mailed out by mid-February. It will contain further details about the outline. If necessary, an online presentation on the outline will be announced as well.
  • We also plan to offer observations with the 70cm telescope (again). Participation will be limited to 4 participants per group, 2 groups per evening, starting November 16, Mondays, Tuesdays and Wednesdays until the end of February depending on request and weather. Observations are voluntarily, ie not required for the participation. Note that strict hygienic rules apply. We have installed air outlets which will exchange the air in the telescope control room 8 times per hour (required by the University). To do so the door to the telescope must be open during the observations, ie it can be very cold while you are observing. Please be prepared for that and consider that when you think on whether you should participate on observations with the 70cm telescope. Details will be given at the end of the first lecture on "Introduction in astronomy and astrophysics" on November 5 around 3.45pm. At that time a DOODLE will be opened which will allow the participants to indicate their preferred dates for the observations. The slides of that presentation will be made public afterwards.
  • Participants who have already registered before November 5 (eg the ones on the preregistration list from the previous astrolab) will reveice the relevant information on that day as well.
  • And yes, we need to say that: if the regulations of the University change (ie the situation gets worse), we may be forced to cancel the observations with the 70cm telesope on a short notice.

  • Location: TBD, most likely Landessternwarte Heidelberg and Philosophenweg 12 Heidelberg
  • Organized by: Prof. Dr. J. Heidt and Prof. Dr. A. Quirrenbach

    Registration required!

    • Ms Wright, LSW Heidelberg, Tel: 06221 - 541781 or online (preferred). If the former, please provide address, phone number and course (PhD, Bachelor or Master). In case of Bachelor or Master, pls. provide also the week preferred and matrikel number.

  • Further information:

    • Procedure: There is no special preparation for the astro-lab required. Altogether 11 tasks will be offered. An introduction to the tasks can be found here. During the one-week astro-lab about 2-4, during the 2-week astro-lab about 6-8 tasks shall be worked on in groups of two (scripts will be given on site or be made downloadable from the WEB). Individual tasks will be assigned by the organizers. Once a task is completed by an individual group, it will be discussed with one of the responsible assistants. There is no need for a written summary or any homework.

    • Literature: It would be useful to bring your own textbooks, e.g.
      • Schneider: Extragalactic astronomy and cosmology
      • Shu: The Physical Universe, University Science Books

    • Very useful: Bring your own notebook for working on the tasks and/or searches in the internet (WLAN/DHCP available). For the data reduction as part of Task 1 dedicated notebooks are available. Knowledge of SW-tools like Origin, Excel or Gnuplot to e.g. fit functions to data would be an asset.

    • Due to space constraints the number of participants is limited to 40 students per week.

    The next astrolab will be held in autumn 2021, the exact dates are TBD.
