Spectral-Type Dependence of Habitable Zone Classification Differences in Confirmed Exoplanets: A Systematic Comparison of Temperature-Dependent and Constant-Flux Models

Aswin Karkadakattil · Journal of Pharmaceutical Research International · 2026

Habitable zone (HZ) boundaries are commonly estimated using either the temperature-dependent formulation of Kopparapu et al. (2013, 2014) or simplified constant-flux models that neglect stellar effective temperature. Although both approaches are widely used in exoplanet studies,...

Field-Based Comparative Performance Analysis of Passive Cooling Strategies for Photovoltaic Modules in Tropical Climates

Aswin Karkadakattil · Journal of Engineering Research and Reports · 2026

Photovoltaic (PV) modules installed in tropical regions operate under intense solar irradiance and elevated ambient temperatures, conditions that can substantially reduce electrical efficiency and accelerate material degradation. Although numerous laboratory-based studies have de...
