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 […]

A study by Eggenberger, Meynet, and Maeder (2002) found that its ratio of blue to red supergiants was in line with other clusters of similar age and position in the galaxy. To properly analyze this cluster myself I made observations using the […]
