You will find different practical work using software to discover the Universe:
- ds9 astronomical software
- js9 online astronomical software
- Exoplanet lab from Harvard (remember your username and password)
Study of exoplanets in a constellation
Simple image map
- Download GIMP portable and install it in your pendrive.
- Download your constellation map (name given by the teacher)
- Create your own image with layers, or add layers with images or drawings of exoplanets, stars, clusters, black holes, pulsars, galaxies, etc. Save as constellation.png
- Go to GIMP>Web>Image map. Create a map file using this tool. Save as constellation.map
- Open the constellation.map with Sublime Text. Replace alt= for title=. Write the correct name of the image file inside commas img src=”correctimagename.png”. Add <html> at the very beginning and </html> at the very end. Write extra information inside title about the sky objects, e.g. spectral type of stars, ESI of exoplanet, cluster type, distance in light years. Save it all as constellation.html.
- All file must be in the same folder: constellation.html and constellation.png in order to be opened easily with a browser.
Improved image map
- Use mapper.js library to improve image map
Exoplanet data analysis
- Take pictures with your Harvard Astronomy Laboratory account
- Analyse the data with astroimageJ http://www.astro.louisville.edu/software/astroimagej/
- Create correlation plots with exoplanet data
Harvard Exoplanet Laboratory activities
- Use the user name and password (do not change it) given to be used in the website of Laboratory of Exoplanets (University of Harvard).
- Simulate the transit orbit of an exoplanet in the modelling lab and change the size, the speed and the tilt angle of the exoplanet
- Create the transit orbit graph and write why it must be that way and save your graphs and comments in the Harvard intranet for teacher evaluation.
- Go to the telescope area and move the Arizona telescope to the available explanets and obtain your photographs.
- Choose the exoplanet and the conditions for photography (exposition times, etc)
- Go the image lab in the website after the photos are taken.
- Analyse the data from the photos and write your conclusions from your photos by using the available sofware (use only your own photographs, measure darkness level and substract it from the target star)
- Write your report online. You can improve the simplified model of Harvard by using the methods in R found in the scientific article of Proxima b or others.
- Create an image map of the constellation and draw using new SVG programming or HTML image map.
- The previous constellation must contain the main stars, the exoplanet and other objects (galaxies, nebulae, star clusters, black holes, pulsars, etc) with some information when the mouse is over and when the object is clicked.
Below is a Satellite Overpass Schedule listing the times at which satellites will fly over Martorell.
Please make your ground observations of the clouds within +/- 15 minutes of the overpass times listed below to ensure you are observing the same set of clouds from which the satellite is collecting data.
And remember you can always look up observations and matching satellite data using the S’COOL Database.
