New models of reflection spectra for terrestrial exoplanets: Present and prebiotic Earth orbiting around stars of different spectral types
Manika Singla, Sujan Sengupta
In order to recognize a habitable exoplanet from future observed spectra, we present new model reflected spectra and geometric albedo for modern and prebiotic (3.9 Ga) Earth-like e…
A comprehensive model of morphologically realistic Cosmic Dust particles: an application to mimic the unusual Polarization properties of the interstellar Comet 2I/Borisov
Prithish Halder, Sujan Sengupta
The cosmic dust particles found in space are mainly porous aggregates of smaller grains. Theoretically, these aggregates are replicated using fractal geometry, assuming a cluster o…
Effect of multiple scattering on the Transmission spectra and the Polarization phase curves for Earth-like Exoplanets
Manika Singla, Aritra Chakrabarty, Sujan Sengupta
It is the most appropriate time to characterize the Earth-like exoplanets in order to detect biosignature beyond the Earth because such exoplanets will be the prime targets of big-…
Atmospheric heat redistribution effect on Emission spectra of Hot-Jupiters
Soumya Sengupta, Sujan Sengupta
Hot Jupiters are the most studied and easily detectable exoplanets for transit observations.However, the correlation between the atmospheric flow and the emission spectra of such p…
Transit Light-curves for Exomoons: Analytical Formalism
Suman Saha, Sujan Sengupta
The photometric transit method has been the most effective method to detect and characterize exoplanets as several ground-based as well as space-based survey missions have discover…
Polarization of Rotationally Oblate Self-Luminous Exoplanets with Anisotropic Atmospheres
Aritra Chakrabarty, Sujan Sengupta, Mark S. Marley
Young self-luminous giant exoplanets are expected to be oblate in shape owing to the high rotational speeds observed for some objects. Similar to the case of brown dwarfs, the ther…
