After the lessons, we will make the presentation slides available through
the University's e-learning system. Links will be posted here: stay tuned...
Software list
The software packages needed for the exercises will be made available on the
URZ computers for all the course participants, so you don't need to take
care of the computing/software needs yourself. If you so wish, you are
welcome to bring your own laptop and work on it as well, but you should take
care to install the needed/desired software yourself. Here follows a list of
the software we plan to use for the course:
- NOAO-IRAF, astronomical data reduction package, available through the
project homepage, or perhaps more conveniently bundled together
with other useful packages (some of which are required too for the
course) in the SCISOFT
package by ESO
- GASGANO, the ESO data organization tool, also used as an interface to
run the UVES pipeline. Get
it from ESO
- The UVES CPL-based data reduction pipeline. All the ESO pipelines can
be downloaded
from this page. Download the GASGANO based pipeline, NOT the
REFLEX one. Notice GASGANO is also delivered with the pipeline, so if
you plan to install the pipeline do not install GASGANO over it
or the pipeline will not work. Installing the pipeline over a
pre-existing GASGANO is OK.s
- Skycat / Gaia, astronomical images visualization tool, or DS9, to
visualize 2D spectra. They both are bundled in
the SCISOFT package by ESO.
- MOOG will
be used to perform the abundance analysis, parameter determination, and
spectrum synthesis. Notice that MOOG needs
SuperMongo to compile, so, unless you have said package available
on your computer, it will not compile. Unfortunately, SM is not avilable
for free.
-
IDL will be used for data plotting and parts of the exercises.
Again, IDL is most definitely not free software. Version 7.1 is included
in SCISOFT, but will only work in limited demo mode if not provided with
a license file.
- Fortran and C compiler (Fortran for the course, C is needed to
compile e.g. the CPL pipelines), Java at least 1.5 for Gasgano.
Suggested texts
Here follow some books or papers that you can find in the University library
or, in some cases, download from the web, and that will be useful for the
course. More specific references might be provided during the lectures. They
will be added here as they are chosen, so keep an eye on this page.
- D. F. Gray The Observation and Analysis of Stellar Photospheres
(Cambridge Univ. Press) Comprehensive text describing both the
instrumental and physical side of stellar spectroscopy. Likely the main
reference text throughout the course.
- D. Emerson Interpreting Astronomical Spectra (Wiley)
- C. R. Kitchin Astrophysical Techniques (IoP): Detectors
and instrumental techniques
- C. R. Kitchin Optical Astronomical Spectroscopy (IoP)
Similar to Gray: intrumental as well as physical text on spectroscopy,
with a less strict focus on star.
- D. Mihalas Stellar Atmospheres 2nd edition (Freeman &
Co.) highly theoretical text on stellar atmospheres.
- P. Massey Astronomical spectroscopy is a shorter text that
can be downloaded for free
from arXiv
- The MOOG manual can be downloaded from the MOOG page, here
is the direct link
- The UVES pipeline user manual is here
