Information Gain as a Tool for Assessing Biosignature Missions
Benjamin Fields, Sohom Gupta, McCullen Sandora
We propose the mathematical notion of information gain as a way of quantitatively assessing the value of biosignature missions. This makes it simple to determine how mission value…
Multiverse Predictions for Habitability: Origin of Life Scenarios
McCullen Sandora, Vladimir Airapetian, Luke Barnes +2
If the origin of life is rare and sensitive to the local conditions at the site of its emergence, then, using the principle of mediocrity within a multiverse framework, we may expe…
Multiverse Predictions for Habitability: Stellar and Atmospheric Habitability
McCullen Sandora, Vladimir Airapetian, Luke Barnes +1
Stellar activity and planetary atmospheric properties have the potential to strongly influence habitability. To date, neither have been adequately studied in the multiverse context…
Multiverse Predictions for Habitability: Planetary Characteristics
McCullen Sandora, Vladimir Airapetian, Luke Barnes +1
Recent detections of potentially habitable exoplanets around sunlike stars demand increased exploration of the physical conditions that can sustain life, by whatever methods availa…
Imaging of exocomets with infrared interferometry
Markus Janson, Jayshil Patel, Simon C. Ringqvist +6
Active comets have been detected in several exoplanetary systems, although so far only indirectly, when the dust or gas in the extended coma has transited in front of the stellar d…
Multiverse Predictions for Habitability: Element Abundances
McCullen Sandora, Vladimir Airapetian, Luke Barnes +2
We investigate the dependence of elemental abundances on physical constants, and the implications this has for the distribution of complex life for various proposed habitability cr…
