NGC 6134: a comprehensive study through photometric and kinematic analysis using Gaia DR3
Agus T. P. Jatmiko, Teduh Perhati, Dhimaz G. Ramadhan +7
Open clusters provide a unique laboratory for precisely constraining stellar age, distance, and metallicity, facilitating studies on exoplanet-host star correlations. Building on o…
Analysis of a Septuple Open Cluster System and Its Extended Family in Gaia DR3
Muhammad Akmal Husain, Ferdinand, Mochamad Ikbal Arifyanto +1
A rare multiple open cluster system has been analyzed using Gaia DR3 astrometry and photometry data. Using Agglomerative Hierarchical clustering and Bayesian-HDBSCAN, we identify a…

Muhammad Akmal Husain, Irham Taufik Andika, Mochamad Ikbal Arifyanto
PSO J083.8371+11.8482, a quasar at with a nearby companion galaxy, provides an opportunity to study the impact of active galactic nucleus (AGN) activity on the surroundi…
Comparing dark matter and MOND hyphotheses from the distribution function of A, F, early-G stars in the solar neighbourhood
M. A. Syaifudin, M. I. Arifyanto, H. R. T. Wulandari +1
Dark matter is hypothetical matter believed to address the missing mass problem in galaxies. However, alternative theories, such as Modified Newtonian Dynamics (MOND), have been no…
