NGC 3766 is a young cluster in the Southern constellation Centaurus. It was discovered on March 5, 1752, by Nicolas Louis de Lacaille. The cluster has 137 listed stars but most of the stars were non-members with only 36 containing accurate photometric data. This star cluster is also known as the pearl cluster. The cluster has eta Carinae where astronomers believe that once it explodes it’s going to become a spectacular supernova.Â
In the study by Mowlavi in 2013 he analyzed based on the photometric seven-year survey and detected 13 SPB and 14 Scuti candidates.
To study the cluster NGC 3766 and investigate the relationships between the colors, brightness, and age I used filters of B, R, and V to telescopes to collect images using Skynet. I used Afterglow for the images that were collected to make the images clear and visible so that I could analyze the image and find the giants, blue stragglers, etc. I used cluster astromancer I discovered the distance, proper motion, log of age, metallicity, etc.
With the result, I got from the images I can conclude that two red color stars are showing that this is a younger star. By analyzing the cluster I could determine that the cluster has no blue stragglers. The cluster doesn’t show any sign of a nebula so I could determine that the cluster has no nebula. By the looks of it from the image, there seems to be a giant in the cluster. What I thought was challenging to analyze was determining whether the cluster had any blue stragglers or not.
The star cluster NGC 3766 was studied by Andre Monitinho and Emilio J. Alfaro and found the parameters for the cluster. With the parameters, I could learn about the age of the star and this gave me some insight into the history of the evolution of the stars. The location of the star cluster and the distance of the star cluster of how far the star cluster is from the Earth.
This was one of the projects I had fun working on in this class and I would like to do something like this again in the future. I had enjoyed my time in ASTR 113 and this was my first Astronomy class so it was really fun and enjoyable. I would recommend this class to people who need a science credit one of the best science classes I ever took. It was fun learning about the stars and their evolution what happens to stars when they die and learning about giants was fun.
