Abstract

Habitability of exoplanets is an intriguing and complex phenomenon. Ever since the seminal work by Schulz Makuz et. al., metrics for habitability have been used to evaluate exoplanet candidates for habitability. Following the work by Schulz Makuz et. al., Bora and Saha proposed metrics from a convex optimization perspective and reconciled machine learning principles with their metric. The current manuscript studies the relationship between the two metrics, Earth Similarity Index (ESI) and Cobb-Douglas Habitability Score (CDHS) in the context of characterizing exoplanets into different classes. The authors bring out the contrasts between the two metrics and highlight analytical properties of CDHS. Such comparative analysis is important to understand the efficacy of habitability metrics in the study of exoplanets. © 2018 IEEE.
