The Hertzsprung-Russell diagram is an important tool in the classification of stars and the understanding stellar evolution. The H-R diagram was discovered independently by two astronomers in early 20th century using observations of star luminosity and surface temperature. With this lab exercise, you will use Stellarium to collect stellar information and then form your own H-R diagram and see if you can find how stars are group into different luminosity classes. For this project piece, use a computer simulation to measure the characteristics of a sample of stars and then organize your data into a Hertzspung-Russel diagram. Please read through the assignment background information and follow the steps listed in the lab assignment instructions. You will be asked to form a hypothesis, state the lab objective, record your measurements and calculations, and answer each of the lab questions. Follow the instructions contained within and submit your results as this project deliverable. Submit your paper with a title page and in APA format. Module 04 – Measuring and Classifying Stars Instructions The Hertzsprung-Russell diagram is an important tool in the classification of stars and the understanding stellar evolution. The H-R diagram was discovered independently by two astronomers in early 20th century using observations of star luminosity and surface temperature. With this lab exercise, you will use Stellarium to collect stellar information and then form your own H-R diagram and see if you can find how stars are group into different luminosity classes. Background Question – Describe the four major groups of stars and where they are located on the H-R diagram. Object: Explain the purpose of this laboratory assignment in your own words. What do you think you will accomplish or learn from this exercise? Hypothesis: Write a simple hypothesis connected to different stars and the H-R diagram that you will be able to test up the Stellarium software (for example, most bright stars visible in the night are supergiants) Procedure: Open the Stellarium software. Open the Sky and Viewing options window (F4). Under the “Sky” tab, uncheck the Atmosphere and Dynamic eye adaption.Select the Landscape tab and uncheck “Show ground”.For this lab, you will need to record the spectral class and absolute magnitude of a group of near stars and a group of the brightest stars in the night sky. For each star, open the Search window (F3) and enter the star’s name.Click on the star and look at the displayed information at the upper right. Record the star’s spectral class and absolute magnitude in the chart.Some information has already been include in the chart.Repeat step 3 for each of the stars on the list.Plot each of your stars on the H-R diagram below. Denote each star by their listed star number and mark the nearest in red and the brightest stars in blue.Using the H-R diagrams in Chapter 12 as a reference, mark out where the main sequence line, giant branch, supergiants branch, and white dwarfs region would be on your H-R diagram.Continue using Stellarium if you need further information to test your individual hypothesis. If you need further direction, please ask your instructor. Q1: Based on the location of the Sun on your H-R diagram, what luminosity group (main sequence, giant, supergiant, or white dwarf) does the Sun belong to? Q2: What stars did you find to be supergiants? Q3: What luminosity group and spectral classes are most nearby stars? Q4: What luminosity groups and spectral classes do most of the bright stars belong to? Q5: Is there any part of the H-R diagram that you do not find any stars? Conclusion: In 1-2 paragraphs, explain if your observations and data support or conflict with your hypothesis and if you have met your assignment objective. Was there any portion of the assignment that was particularly interesting or difficult?

Select a scenario from the list below: There is a species of fish (with low numbers) that is having trouble traveling up and down the river because of a dam. Chose an area that is economically depressed but has a lot of species diversity, you need to protect the species while providing jobs for locals. An animal is being poached for its horn which is believed in some cultures to cure many diseases, it is not critically endangered. The demand for farming is increasing, which is destroying native forests and affecting their biodiversity. An animal is starting to become isolated because it is afraid to cross roads created by deforestation. Local birds typically migrate over the winter, but people are feeding them and thermal pollution at a local stream is keeping the water warmer the birds are not migrating, resulting in water pollution. A drought has been going on for a period of time; the water needed for homes, businesses, and farms has decreased lake and river levels impacting the amount available for local flora and fauna. Species are being found dead on local beaches due to plastic. Use the textbook and of info-graphic under course materials to find the best resource management practice to implement. Create a pamphlet addressing the following: What is the issue and why it would work Describe the restoration method you selected and why it would be best (with at least 2 examples of how it has worked in similar situations from peer reviewed sources) Time frame to complete the plan (include short and long term objectives) What is the end goal of the restoration project This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.
