Wintersemester 2024/2025

Lehrinhalt

Diese Vorlesung ist der erste Teil der Einführung in die Astronomie und Astrophysik, 
also in das physikalische Verständnis unsres Universum jenseits unserer Erde. 
Laut Modulhandbuch werden wir folgende Themenkreise behandeln:
— Astronomische Grundlagen : astronomische Beobachtung;
     elektromagnetische Strahlung; Entfernungsmessung; Sonnensystem 
— Physik der Sterne: Sternaufbau und stellare 
    Energieerzeugung; Sternatmosphären und Spektren
— Phasen der Sternentwicklung: von der sog. Hauptreihe bis 
    zu Supernovae und schwarzen Löchern
— Physik des interstellaren Mediums: Gas und Staub; 
    Heizung und Kühlung; Anreicherung mit Metallen

Observational methods using photons (from gamma rays to radio), gravitational waves, other particles, and in-situ exploration

Informationen zur Veranstaltung

Lehrinhalt

The lecture is equivalent to the bachelor module parts WPAstro.1+2 during the winter and summer terms but requires a slightly higher level of basic physical knowledge. 


Nevertheless also motivated 3rd semester BSc students are welcome to participate. 
This lecture is organised as a block course with 2 parts from Sep. 23rd - Oct. 11th, 2024. 

Certificates are only given for active participation in the exercises (meaning also being present at all exercises) and passing the written examination.

Homework should/can be done in groups of 2(3)

Bachelor students

You can choose:

WPAstro.1,2:
- 8CP with marks (lab course needed for complete module)
- The written examination will be graded
- Marks count for the full 10CP including the lab course

MVAstro0:
- 8CP, no marks as a master module in the ‘Wahlbereich’
-
Master students (MVAstro0)
- 8CP, no marks - only passed
- Can be used as part of MVMod (specialisation in Astrophysics)
- Can be used as an option: just 8CP

PhD (including IMPRS)
Active participation in exercises is strongly recommended, and a successful written exam for certificate

Lehrinhalt

Diurnal and annual motions, sidereal and solar time clocks, precession and nutation, Earth-sky trajectory of a planet from its orbital elements

Lehrinhalt

The diverse astronomical and astrophysical distance determination methods will be introduced and illustrated with examples, covering all distance ranges from parallax measurements of nearby stars to cosmological methods.

Lehrinhalt

From binaries to Dwarf galaxies and everything in between: Binaries; Star clusters: chemical elements & their formation; dynamics & structure; dwarf galaxies: chemical evolution & Dark Matter; different flavours of star clusters and dwarf galaxies.

Lehrinhalt

As most of the radiation we receive from galaxies is star light, we can use it to measure and study their properties. These lectures aim at showing how much we can learn about galaxy evolution from the study of their stellar populations (young to old stellar clusters, field stars, resolved and integrated stellar populations). We will review the methods commonly used in this respect, all resting on our understanding of stellar evolution, and discuss the results obtained when we apply them to observational data, such as multi-wavelength photometry and spectroscopy.

Lehrinhalt

Stellar structure, evolution and explosions including practical tutorials based on the MESA stellar evolution code

Lehrinhalt

Introduction to the dynamics of systems dominated by gravity (from planetary systems to galaxies) and their numerical treatment.

Lehrinhalt

Lessons learned from gravitational wave sources. Compact object formation from stars and binary stars. Dynamics of compact objects in dense star clusters. Numerical models of compact-object populations.

Lehrinhalt

The physics of the Universe during the Dark Ages between recombination and reionization.

Lehrinhalt

Von der Entstehung der Sonne, über die Entwickliung der Protoplanetaren Scheibe zu Planeten mit ihren Ringen und Satelliten, Exo-Planeten und die Frage der Bewohnbarkeit.

Lehrinhalt

20 Beobachtungsabende nach Vereinbarung

Lehrinhalt

Dieser Kurs wurde von Dr. Thomas P. Robitaille entwickelt, der diesen Kurs viele Jahre lang an der Universität Heidelberg gehalten hat. Aufgrund der Beliebtheit dieses Kurses bieten wir nun mehrere Blockkurse parallel an. Dr. Robitaille hat eine andere Stelle angetreten, so dass dieser Kurs nun von anderen Lehrkräften gehalten wird.

Lehrziel

Ziel dieses Kurses ist es, zu lernen, wie man die Python-Programmierung zur Lösung wissenschaftlicher Probleme einsetzt. Es handelt sich um einen interaktiven Learning-by-Doing-Kurs, der auf einer Reihe von Python-Notebooks basiert und zahlreiche Übungen enthält. Er richtet sich an Bachelor-Studenten.
