### Spring Break

No classes 3/4(M)-3/9(S)

### Week 9

#### 3/12 (T)

I will allow contributions to the following Symposium to replace all or part your exam scores. If it replaces final exam, you must do work after the last day of class. Chapter 21

#### Symposium

• Students interested in presenting a poster that presents new numerical questions using Python, Excel, Matlab are encouraged to submit a poster. I will help you with the details.Guy vandegrift (discusscontribs) 18:57, 11 March 2019 (UTC)
• https://lake.wright.edu/research/research-symposium
• The symposium will be held in Dicke Hall on Thursday April 18, 2019 from 11:00am to 1:30pm. * Refreshments will be provided.
• If you would like to present at this year’s symposium please RSVP your project title, author names, and brief abstract to stephen.jacquemin@wright.edu by the end of the day on Monday March 25, 2019 for inclusion in the program.

1 The Hayashi and Henyey tracks refer to how T Tauri of different masses will move

 through an HR diagram as they die through a cluster as they die through a cluster as they are born Two of these are true through an HR diagram as they are born

2

How do low-mass stars change as they are born?
Birth of stars HR path tracks

 Increasing temperature with no change in luminosity Increasing luminosity with no change in temperature Decreasing temperature and increasing luminosity Decreasing temperature with no change in luminosity Decreasing luminosity with no change in temperature

3 Stellar parallax is

 an annual change in angular position of a star as seen from Earth an astronomical object with known luminosity. the total amount of energy emitted per unit time. a numerical measure of brightness as seen from Earth a numerical measure of brightness as seen from a distance of approximately 33 light-years

4 Luminosity is

 an annual change in angular position of a star as seen from Earth an astronomical object with known luminosity. the total amount of energy emitted per unit time. a numerical measure of brightness as seen from Earth a numerical measure of brightness as seen from a distance of approximately 33 light-years

5 A standard candle is

 an annual change in angular position of a star as seen from Earth an astronomical object with known luminosity. the total amount of energy emitted per unit time. a numerical measure of brightness as seen from Earth a numerical measure of brightness as seen from a distance of approximately 33 light-years

6 Absolute magnitude is

 an annual change in angular position of a star as seen from Earth an astronomical object with known luminosity. the total amount of energy emitted per unit time. a numerical measure of brightness as seen from Earth a numerical measure of brightness as seen from a distance of approximately 33 light-years

7 Relative magnitude is

 an annual change in angular position of a star as seen from Earth an astronomical object with known luminosity. the total amount of energy emitted per unit time. a numerical measure of brightness as seen from Earth a numerical measure of brightness as seen from a distance of approximately 33 light-years

### Week 10

#### 3/19 (T)

Chapter 23 death of stars

### Week 11

#### 3/29 (F)

Played with the two experiments: simultanaety and spray diagrams 2d

### Week 13

#### 4/8 (M)

Lab: Drake's equation

1. Make a sketch showing why N = RL where R is the rate of formation and L is the lifetime.
2. Do an excel spreadsheet showing how f=f1f2f3 for two coins and one dice. Verify the approximation that the standard deviation of S is ${\displaystyle {\sqrt {Nf}}}$ where N is the number of attempts, and S=Nf is the number of successes.

### Week 15

Last day of classes is 4/27(S)

#### 4/22 (M)

Discussed fina. See below.

#### 4/25 (R)

continue with above.

## Astronomy_Final_Exam_2019

Takehome final exam for all, in class final for some

1. Details will be announced on Wikiversity on Friday 26 April. These details will include what grade you will get if you don't take the final exam multiple choice test on Wednesday 1 May 1-3 pm. You will be informed by Pilot before Friday.
2. Regardless of whether you take the final exam, you must submit 10-15 exam questions. This is required by all students, but not all students are required to take the final exam on Wednesday 1 May from 1-3pm.
3. Attach a pdf, word, or excel document to an email to guy.vandegrift@wright.edu
4. You are encouraged to include short explanations. If you have "poor" or unfinished questions already typed up, don't hesitate to include them as well.

#### 4/29 (M)

2:00 PM deadline for submitting preliminary version of takehome. Email it to guy.vandegrift@wright.edu

#### 4/30 (T)

I will be off-campus all day, but plan to email you with a tentative grade, with suggestions on how to improve it by either adding more questions, or taking the final exam.

#### 5/1 (W)

Final exam is Monday 1 May for those who wish to take it. A study guide can be found at this link:

#### 5/2 (R)

I will be available for most of the day.

#### 5/3 (F)

11:59 PM deadline for submitting final version of the takehome.
