Astronomy Teaching and Research Orientation Workshop (AsTROW)

Date: 15 to 19 October 2012

Venue: South African Astronomical Observatory, Cape Town

Target: Small group (<10) lecturers from South African Physics Departments

Summary:

This programme aims to provide hands-on training on observational astronomy using both real and virtual observatories and is targeted at interested people from under-resourced universities.

Small aperture optical telescopes (6-8 inches) with adequate back-end instrumentation such as a photometer can be effectively used for teaching and research in astronomy. This is ideally suited for projects such as continuous monitoring of a variety of variable stars which in turn can provide valuable data for understanding the physics of stellar variability. Below we outline some of the projects that can be used for student training in observing techniques, data acquisition, reduction and analysis, as well as interpretation of the results:

  1. Measurement of atmospheric extinction
  2. Photometric calibration of telescope-photometer system
  3. H-R diagram of nearby bright stars and star clusters like Pleiades
  4. Tracing light curves of various types of variable stars, such as cepheids, Delta Scuti stars, eclipsing binaries like Algol

Apart from this, data archives within the framework of virtual observatories provide vast astronomical resources, along with very easy-to-use but highly sophisticated analysis techniques. These techniques allow interested people to conduct highly informative projects/exercises with relatively simple and inexpensive software tools. The Virtual Observatory (VO) is not only a powerful medium to provide training and education but also provides resources to conduct astronomical research projects. Below we listed some VO projects that can used for training, education and research:

  1.  Proper motion of stars
  2. H-R diagram of star clusters using SDSS data
  3. X-ray spectroscopy of Supernova remnants
  4. Galaxy clusters in SDSS

The workshop will be divided into three parts:

1. Lectures:

  • Basic astronomy
  • Telescopes/CCDs
  • Basic knowledge of Stars and Galaxies

2. Tutorials (hands-on data reduction and data mining)

  • Lab session on computers
  • Learning Linux
  • Browsing data archives
  • Getting familiar with data reduction recipes

3. Observing at night

  • Glimpse of night sky,
  • Identifying objects – stars/star clusters/ planets etc.
  • Operating the telescope and instrument
  • Pointing telescope and acquiring data etc.
