Classification Revision of Variable Stars

I have taken a look at around 14 variable stars and their current classification, and found several that I would like to recommend revision on after looking at newer data. Two of the most notable were the stars ASAS J011054-1857.6 and ASAS J082143-2308.4. ASAS J082143-2308.4, Which I will refer to as “Star 1” from now […]

TT Lyn and ROTSE1 J172446.33+435021.7

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. […]

V1059 Cas and ASAS J203832-1856.5

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 […]

ASAS J082841-2735.0 and The O’Connelle Effect

According to Gaia, ASAS J082841-2735.0 has a Right Ascension of -7.248 +/- 0.506 mas/y and Declination of 1.915 +/- 1.054 mas/y. 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 […]

DD Hya and El Aps

The binary stars DD Hya and EL Aps are two pairs of stars that orbit around each other in space. DD Hya is located in the constellation of Hydra, The Water Monster., while EL Aps is found in the southern skies. This analysis gave us a piece of certain information about the star cluster such as […]

RY Col

RY Col also known as Ry Columbae is a star variable that’s located in the constellation of Columba. A variable star is a star whose brightness can be seen from Earth and over time variable star brightness can be changed. Variable stars can be classified into two categories intrinsic and extrinsic variables. The variable stars […]
