CSUN Planet Formation and Exoplanets Properties Lab Report

Lab Report #11 – Planet Formation and Exoplanets Properties

Purpose: In this lab, we will first study the temperature and composition of the disk of material surrounding the Sun, just after the Sun formed. The planets formed from this disk of material. By studying the temperature and composition of this disk, we will be able to predict the composition we expect for each planet in the Solar System. In the second part of the lab, we will study the NASA Exoplanets website to learn about the different types of exoplanets, the main strategies to detect exoplanets, and some of the big and exciting discoveries in this young and active field.

Part 1: Temperature in Solar Disk and Planet Formation

Astronomers believe that the planets in our Solar System formed at the same time that the Sun formed. There is good evidence for this theory from observations of other young stars. In this theory, the Sun formed in a cold and dense molecular cloud. As the cloud collapsed and the Sun formed at the center of the cloud, the cloud began to spin faster and faster. As the cloud spun faster and faster, it flattened into a disk. The planets formed from this disk of material that surrounded the Sun. A table with the four main materials in the disk are shown below. The percentage of each material in the disk and the melting point for each material is also shown in the Table below. If the temperature is higher than the melting point of a material, the material will melt and it will change from a solid to a liquid.

Let’s first analyze the table above to determine some of the important properties of the disk and the materials.

1. Which material is the material that is least available in the disk?

2. Which material is the material that is most available in the disk?

3. Which material in the disk has the highest melting point?

In order for a material to become part of a planet, it needs to be in the solid phase. If the temperature is below be melting point of a material, then the material will be in the solid phase and it can be part of a planet.

4. Which material(s) in the disk are solid at a temperature of 200K?

5. Which material(s) in the disk are solid at a temperature of 1000K?

6. Which material(s) in the disk are solid at a temperature of 1600K?

7. Which material(s) in the disk are solid at a temperature of 2000K?

Math 482 computational method for data analysis

Rock & Roll and the Gabor Transform

1. Through the use of the Gabor filtering we used in class, reproduce the music score for the guitar in the
GNR clip, and the bass in the Floyd clip. Both are clearly identifiable. See Figure 1 which has the music
scale in Hertz. (NOTE: to get a good clean score, you may want to filter out overtones… see below. NOTE
2: It is also helpful to plot the log of the spectrogram… so plot log(|s| + 1) where s is the spectrogram.)
2. Use a filter in frequency space to try to isolate the bass in Comfortably Numb.
3. See how much of the guitar solo you can put together in Comfortably Numb. It may help to look at smaller
portions of the clip to guide your reconstruction of the music score.

Prompt

• Create a complex 3D object using at least two primitive shapes. The object you create should be reflective of one object from your 2D scene. At this stage of your object’s creation, you should add different colors to each vertex of the object. This will help you better visualize the variance between the different parts of the shapes you are creating. Note that the code you already have uses rainbow colors on the shapes that are provided; if you use this code you may keep that rainbow format. Remember, the shapes you may wish to use are as follows:

  • Cube

  • Cylinder

  • Plane

  • Pyramid

  • Sphere

  • Torus

• Apply transformations so shapes are scaled, rotated, and translated (placed) correctly. This work should be relevant for the 2D reference image. For example, if you are working with a cylinder, should it be standing up or lying on its side, based on the image you are referencing? If you are also creating a cube, where should it be placed relative to the cylinder? What sizes are the two objects when compared to each other? It will be easier if you complete these transformations in the right order for your specific object. In general, you will wish to first scale, then rotate, and then translate. While this is not always the case, that is the most likely order for your process to follow.

• Create code that follows a logical flow without syntax errors. The code you create needs to be executable and all the code that is included will have to be reached by the execution. Note that not everything should be written in a single function and your work should be well-modularized.

• Apply coding best practices in your creations. Pay particular attention to the way you format and comment your code. Program code should be easy to read and follow industry standard code formatting practices, such as indentation and spacing. Commenting best practices should be in place to ensure the source code is briefly and clearly explained using descriptive comments

The Social, Economic and Sanitary Impact of COVID-19 Pandemic

Additional Guidelines:

• You must select articles (not book review essays, which tend to appear toward the end of the journal and are much shorter in length than articles).

• Be sure that your answers to each of the questions go beyond making obvious observations.

• Include a References list that follows the formatting guidelines of your journal such as APA, MLA, CMS, etc. Note that many journals have their own specific style formatting guidelines.

• Your bibliography should include all the information for the five articles, including a link to the pdf.

Choose to either create your Mind Map using one of several online tools or with paper and (colored) pens/pencils. When you’re ready to begin, put the words Criminal Justice in the center of your paper or screen. Ask yourself, “What are areas of Criminal Justice interest me the most, and what specific topics/issues/problems/questions do I have that I want to find the answer to?” Think about your experiences growing up, interacting with children, studying/working with youth, etc. What are some of the issues that you noticed within those environments that could fall under Criminal Justice? The goal is to let your mind follow the nature flow of ideas.
