Probing the magnetic fields and dust properties in the young embedded star-forming region AFGL 6366S using Near Infrared and Optical linear polarimetry
Samrat Biswas, Biman J Medhi, Motohide Tamura +2
We present Near-Infrared (NIR) and Optical linear polarimetry towards the partially embedded cluster AFGL 6366S. The polarization ranges from 0.44-10.3 per cent in NIR and 0.16-11.…

Exploring the habitability and interior composition of exoplanets lying within the extended habitable zone
Sushmita Deb, Kaushal Sharma, Samrat Biswas +1
Studying the habitability, internal structure and composition of exoplanets is crucial for understanding their potential to sustain life beyond our solar system. Characterizing pla…
