Determine the spectral and luminosity types for each.The telescopes will be equipped spectrographs. You have been granted unlimited observing time on a 0.4 meter optical telescope and permission to request time on a 1.0 meter and/or 4.0 meter optical telescopes. From these fundamental facts, many more properties of the star can be extrapolated: its mass, its distance, its life history.the list goes on and on. By determining the spectral type of a star, we can find its temperature, luminosity, and color. Similar to the spectroscopy we performed in lab previously, astronomers look to stellar spectra to determine many things about a star. We will start by examining stellar spectra. Click to download the Student Manual for this exercise.Ī clickable link is provided on the course web, and remember that you can run these programs any time the lab LSC 174 is open. We will not be able to get observing time on a real telescope, but the VIREO (The VIRtual Education Observatory) program we will use has been designed by astrophysicists to reproduce an accurate observing experience. What that means to us is that we can simulate the observing experience with astonishing realism. It is now possible for an astronomer in Arkansas (or wherever) to perform observations using a telescope in Arizona (or anywhere), without ever leaving home. Data collection can be performed at precise and regular intervals, with the information stored on computers, either local or remote. The telescope can be positioned on the desired object as quickly as the astronomer can type the coordinates into the computer. The observatory dome can be opened at the touch of a button. Over the past thirty years, telescopes have become increasingly automated.

Once upon a time, astronomers had to perform their observations in cold, open-air observatories, using telescopes which had to be positioned by hand. Chapter 13: Neutron Stars and Black Holes.
