Discovery of an Unbound Flyby Companion of UBC 63: In the Immediate Aftermath of a Close Encounter
Samrat Biswas, Biman J Medhi, Sergio Messina +8
We re-investigate the open cluster UBC 63 using the Gaia DR3 data and show that, rather than being a single cluster as previously classified, it is a compelling candidate for a dou…

The effect of metallicity on the Leavitt Law using phase-dependent properties of classical Cepheids
Gautam Bhuyan, Shashi Kanbur, Sukanta Deb +5
The absolute calibration of period-luminosity (PL) relations of Cepheids in the Milky Way (MW) and its nearby galaxies has been a cornerstone in determining extragalactic distances…

Multiwavelength study of observed and predicted pulsation properties of First overtone Cepheids in the Magellanic Clouds
Kerdaris Kurbah, Shashi M. Kanbur, Sukanta Deb +4
We present a detailed analysis of the light curves and pulsation properties of First Overtone (FO) Cepheids in the Magellanic Clouds (MCs) obtained using observations and predictio…
