Bioverse: Assessing the Ability of Direct Imaging Surveys to Empirically Constrain the Habitable Zone via Trends in Albedo

The Astronomical Journal
Will future direct imaging missions such as NASA’s upcoming Habitable Worlds Observatory (HWO) be able to understand Earth-sized planets as a population?

Tidal Constraints on Planetary Habitability

, 2009
We review how tides may impact the habitability of terrestrial-like planets. If such planets form around low-mass stars, then planets in the circumstellar habitable zone will be close enough to their host stars to experience strong tidal forces.

Rebuilding the Habitable Zone from the Bottom up with Computational Zones

Astrobiology
Computation, if treated as a set of physical processes that act on information represented by states of matter, encompasses biological systems, digital systems, and other constructs and may be a fundamental measure of living systems. The opportunity for biological computation, represented in the propagation and selection-driven evolution of information-

Probing the limits of habitability: a catalogue of rocky exoplanets in the habitable zone

Monthly Notices of the Royal Astronomical Society
ABSTRACT While most of the 6000 discovered exoplanets are highly unlike the Earth, the first rocky worlds in the habitable zone (HZ) provide intriguing targets for the search for life in the cosmos. As detections increase, it is critical to test the empirical HZ as well as its limits using known exoplanets. However, there is not yet a

Modeling the Impact of Unresolved Stellar Companions on Detection Sensitivity in Kepler’s Small-planet Occurrence Rates

The Astronomical Journal
Unresolved stellar companions can cause both underestimations in the radii of transiting planets and overestimations of their detectability, affecting our ability to reliably measure planet occurrence rates.

The habitable zone for Earthlike exomoons orbiting Kepler-1625b

, 2018
The recent announcement of a Neptune-sized exomoon candidate orbiting the Jupiter-sized object Kepler-1625b has forced us to rethink our assumptions regarding both exomoons and their host exoplanets. In this paper I describe calculations of the habitable

Ultraviolet and Chromospheric Activity and Habitability of M Stars

The Astrophysical Journal
M-type stars are crucial for stellar activity studies because they cover two types of magnetic dynamos and are particularly intriguing for habitability studies due to their abundance and long lifespans during the main-sequence stage.

Dynamical Viability Assessment for Habitable Worlds Observatory Targets

The Astronomical Journal
Exoplanetary science is increasingly prioritizing efforts toward direct imaging of planetary systems, with emphasis on those that may enable the detection and characterization of potentially habitable exoplanets.
