Advanced Stellar Evolution (5), Autumn 2016
Advanced Stellar Evolution (10), Autumn 2016, Second Quarter
See the end.
This page concerns both the
5 ECTS course Advanced Stellar Evolution (5) and the
10 ECTS course Advanced Stellar Evolution (10).
The page gives access to Ugesedler from this course,
as pdf files.
For simplicity, the numbering refers to the 10 ECTS course.
The ugesedler relevant for the Q2 course is therefore, obviously,
Ugeseddel 8 - 14 (there is no Ugeseddel 7).
Relevant material will be added as links throughout the course.
- Mondays, 14.15 - 16, room 1520-616.
- Thursdays, 9.15 - 11, room 1520-516.
Start: Monday 7 November
- Exercise classes:
- Wednesdays, 10.15 - 12, room 1520-616.
Start: Wednesday 16 November
The lectures will be given by Günter Houdek and me.
The exercise classes will be conducted by Remo Collet.
Start of Q2
Since I am away on 3 November, we delay the start of the lectures until
the following Monday, 7 November.
Here we shall discuss the organization and contents of the course,
and start the lectures.
This will be supplemented by material handed out, as well as by
the presentations at the lectures, which will be made available here.
The MESA package
The MESA package is a user-friendly code for stellar modelling
which we shall use for projects to compute
stellar evolution, including possibly some of the final projects for the
evaluation of the course.
For an introduction to MESA, see
the MESA web page.
Jakob Mosumgaard has made notes specifically on the use of MESA on
our system, either by using a central installation on our servers
or by installing it on your (Linux or Mac) laptop:
Evaluation of the course
The courses will be evaluated
based on reports on topics related to the course.
A list of possible topics, with relevant references,
are available here as a PDF file.
Each topic can be used only once, for this course.
Please send me an e-mail as soon as possible with the number of your
choice of project.
Below is a list of topics that have already been selected.
The deadline for submission of the report is 23 January 2017.
Note that the following links are useful to search for, and download,
the papers that you need for the project:
- The ADS
(Astrophysics Data System) Server maintained by the Smithsonian Institution
and NASA. This gives links to a huge number of astrophysical papers, either
in current journals or (for slightly older papers) scanned.
a comprehensive and much used astrophysical preprint server.
Topics already reserved:
1, 2, 4, 5, 6, 10
Some comments on convection
The weaknesses of the mixing-length treatment of convection,
discussed in the lectures, are obvious.
Although more sophisticated formulations have been proposed,
the best way to gain insight into stellar convection is undoubtedly
to carry out numerical simulations that are as realistic as possible.
Perhaps the best simulations of this nature were started
by Åke Nordlund, Copenhagen
and Bob Stein, Michigan, and have more recently also been continued
by Regner Trampedach and Remo Collet.
Complexity of stellar modelling
This diagram illustrates the complex
interactions between the different aspects of reasonably realistic
stellar modelling (see Mathis & Zahn (2005; A&A 440, 653);
Zahn (2008; Proc. IAU Symp. 252, p. 47)).
We are still far from a complete understanding of stellar structure
