Variable stars stand out for their rhythmic luminosity changes, which make them essential subjects for astronomical studies. Through Lab 7, I had the opportunity to engage closely with several of these objects, applying data from sources like Gaia and SIMBAD to my own observational data to deepen my understanding of variable stars and their characteristics. […]
Read more "TT Lyn and ROTSE1 J172446.33+435021.7"This lab analyzed variable stars from the American Association of Variable Star Observers’ International Variable Star Index, which had magnitudes between 9 and 12.5. The stars were also classified as potential RR Lyrae variable stars. The goal of the lab was to determine if the classification was correct. In order to do this, we used […]

The star was previously studied by G.Pojmanski, Acta Astronomica (2002) and afterwards, there has not been any research paper on the target. With further research from VSO, I found out that the star was […]
Read more "ASAS J082841-2735.0 and The O’Connelle Effect"The universe, a vast expanse of space that is home to countless galaxies, stars, and celestial bodies, has always been a subject of fascination and curiosity. Among these celestial wonders is NGC 2345, a young open cluster located in the Southern hemisphere constellation of Canis Major. Stellar clusters stand as celestial laboratories, offering researchers a […]
Read more "NGC 2345"NGC 2539 is an intermediate age open cluster located in the northern part of the Puppis constellation that was discovered by William Herschel on January 31, 1785. Out of all the hundreds of stars in the cluster there is estimated to be at least one triple system (Mermiliod and Mayor, 1989). I collected a total […]
Read more "NGC 2539"NGC 2335 is an Open Cluster in the Monoceros constellation. Discovered on Jan 10, 1785, by William Herschel, it is situated close to the celestial equator, and, as such, is at least partly visible from both hemispheres at certain times of the year. NGC 2335 is also the gateway to the Seagull Nebula and is […]
Read more "NGC 2335"Introduction NGC 3766, also known as Caldwell 97, is a striking star that may be seen in the Centaurus constellation in the southern sky. It was initially cataloged as NGC 3766 in 1751 while on a trip to the Cape of Good Hope. This cluster has captured the interest of astronomers all over the world. […]
Read more "NGC 3766"NGC 5286 is an old globular cluster in Centaurus, which is 35,900 light years away from Earth. It is 4 arcminutes North of M Centauri. The first record of NGC 5286 was in 1827, noted by Scottish astronomer James Dunlop. It is believed to be one of the oldest clusters in the galaxy, with an […]
Read more "NGC 5286"NGC 2571 is an open young Cluster in the Puppis Constellation, and it is situated of the south celestial equator means it is more easily visible from the southern Hemisphere. NGC 2571 was identified during the era of systematic sky surveys in the 19th century, and it was Compiled by John Dreyer in 1880’s). open […]
Read more "NGC 2571"NGC 4590, also known as the “Gloomy Cluster,” is a captivating star cluster located in the constellation Hercules. First discovered by William Herschel in 1784, this cluster is distinguished by its high stellar concentration and relatively young age of approximately 1.2 billion years. A recent study led by Ahmet Guldadov in 2024 aimed to unravel […]
