Variable Star: BE Lyn

Pierce v. Hengst

What is be lyn
What is BE Lyn?

  • BE Lyn is a Delta Scuti type variable star. This means that it quickly changes brightness.

  • BE Lyn is part of the Lynx constellation.

  • The Lynx constellation actually looks nothing like a lynx. When it was discovered, the astronomer was quoted as saying that it was so dim that it could only be seen by a person with the eyes of a lynx.

What is a variable star
What is a Variable Star?

  • Many stars do not shine with a constant brightness like our Sun, these are called Variable Stars.

  • Different Variable Stars change for different reasons. A Delta Scuti variable, like BE Lyn, changes because of the reactions taking place inside its shell.

The tools used

ST-8 CCD Imager



The Sky 6

8” Schmitt Cassegrain

The Tools Used

The process
The Process

  • Over 2 nights and 5 hours, I took over 418 images of BE Lyn and its neighboring stars. Each one looking similar to this.

The process1
The Process

  • The program that I used to analyze the images was called Canopus.

  • Using Canopus, you choose 5 stars and the variable. The program will measure the variability of the selected star against the 5 other unchanging stars.

  • This will produces a graph that will show the light curve.

The process2
The Process

  • Every image had to be sorted, more then once, by hand to ensure that only the accurate, clear images were used.

  • This is, to say the least, a mind numbing process.

  • This was only made worse by computer error and compatibility issues, which forced me to do the process twice over for a result.

The results1
The Results

  • With the graph I created from the information I gathered, you can see that the period is 2.06 hours.

  • The graph reaches a peak of -.20, and a trough of .20. This shows that over the course of 2.06 hours, it deviates .20 magnitude on either side.
