Purpose(s) of Lab:
To observe very old stars and their late stages of evolution. Also to prefer some online information gathering on each object such as distance, brightness, mass, age, or other characteristics of each object observed. NO THEORY FOR THIS LAB.
Apparatus used in the Lab:
We will make use of the following apparatus at the Schiano Observatory in Irvine J
Celestron 14HD telescope with f7 ‘focal reducer’ to increase visibility of dim objects in Irvine. Maillinicam DS10CTEC camera to record images of the objects within a typical 1 minute to 5 minute (depending on object dimness) ‘integration’ time. A PC and monitor set up to allow viewing of the objects. We will use the SA 100 diffraction grating to see the spectra of some objects. We will use a Narrow Emission Line Nebular Filter (Optolog L-enHance) to increase the contrast (signal to noise ratio) to compensate for light pollution. We will also use the RSpec spectroscopic software application to analyze some oi the spectra,
Task 1: Professor Schiano will aim the telescope at Planetary Nebulas, Wolf Rayet Stars and their associated outflows, and Supernova Remnant Nebulae. He will announce the names of the objects and provide any information to be included on the Lab Report.
• Note the name and the time of your observation and any other data such as the sky conditions that are relevant to your observation.
• Note the brightness, color, and position of any stars in the monitor view.
Task 2: Professor Schiano will send you pictures we took of the objects through Canvas.
• Include the images in your lab report as Data. Include any shared material on the object. In some cases, the images will be spectral images of stars and Nebulae as well as Spectra from the Rspec
Task 3: For each object, perform online research on the object. Aim for one large paragraph of material per object. Try to include:
• Name of Object
• Type of Object
• Distance to Object
• Size of Object in Light Years
• Mass of Object
• Any information on associated the Nebulae
Your lab report will consist the usual lab report format. Do not forget to include the images provided to you as the DATA for the lab. And also include Also include any information on the objects shared by Professor Schiano in the observing session.
