Dark Matter in the Galaxy: Insights from the Dynamics of Stellar Streams
Mohammad Ayaz, Priya Hasan
Dark matter constitutes most of the matter in the Universe, yet its fundamental nature and distribution remain poorly understood. Stellar streams, formed through the tidal disrupti…
On the Constancy of Binary Star Fractions in Local Star Clusters
Priya Hasan, Mohammed Saifuddin
We investigate the unresolved binary-star fraction in a complete sample of 376 open clusters located within 1 kpc of the Sun using Gaia DR3 and ASteCA based synthetic colour magnit…
The Era of Extremely Large Optical Telescopes II: The GMT and TMT
Priya Hasan
The advent of Extremely Large Telescopes (ELTs) ground-based optical and infrared observatories with primary mirrors exceeding 20m marks a transformative era in observational astro…
The Era of Extremely Large Optical Telescopes: The ELT
Priya Hasan
The advent of Extremely Large Telescopes ELTs, ground-based optical or infrared observatories with primary mirrors exceeding 20 m heralds a transformative epoch in observational as…
The Betelgeuse Enigma: The Betelbuddy Hypothesis
Priya Hasan
In the past six years, Betelgeuse has been in the news and drawn significant public interest. Starting in October 2019, Betelgeuse underwent a striking dimming event, fading from m…
Status of Astronomy Education in India: A Baseline Survey
Moupiya Maji, Surhud More, Aniket Sule +28
We present the results of a nation-wide baseline survey, conducted by us, for the status of Astronomy education among secondary school students in India. The survey was administere…
A Detailed Study of Dwarf Galaxies in the Core of the Coma Cluster
Nagamani Poloji, Priya Hasan, S. N. Hasan
In an earlier paper, we determined the morphological types of galaxies in the Coma Cluster using data from the HST/ACS Coma Cluster treasury survey. We found that of the 132 member…
Membership determination in open clusters using the DBSCAN Clustering Algorithm
Mudasir Raja, Priya Hasan, Md Mahmudunnobe +2
In this paper, we apply the machine learning clustering algorithm Density Based Spatial Clustering of Applications with Noise (DBSCAN) to study the membership of stars in twelve op…
Using GMM in Open Cluster Membership: An Insight
Md Mahmudunnobe, Priya Hasan, Mudasir Raja +2
The unprecedented precision of Gaia has led to a paradigm shift in membership determination of open clusters where a variety of machine learning (ML) models can be employed. In thi…
Exploring the collinear Lagrangian points of exoplanet systems with P-R drag and oblateness
Ibtisam Shaikh, Priya Hasan, S. N. Hasan
In this paper we study the location and stability of the collinear Lagrangian points for the RTBP for the case in which one of the primary bodies is radiating and the other is obla…
Status of Women in Astronomy: A need for advancing inclusivity and equal opportunities
Mamta Pandey-Pommier, Arianna Piccialli, Belinda J. Wilkes +12
Women in the Astronomy and STEM fields face systemic inequalities throughout their careers. Raising awareness, supported by detailed statistical data, represents the initial step t…
Gaps in the Main-Sequence of Star Cluster Hertzsprung Russell Diagrams
Priya Hasan
The presence of gaps or regions of small numbers of stars in the main sequence of the Hertzsprung Russell Diagram (HRD) of star clusters has been reported in literature. This is in…
Deep Photometry of Suspected Gravitational Lensing Events: Potential Detection of a Cosmic String
Margarita Safonova, Igor I. Bulygin, Olga S. Sazhina +3
Cosmic strings (CS) are one-dimensional cosmological-size objects predicted in realistic models of the early Universe. Analysis of the cosmic microwave background (CMB) anisotropy…
