Circumbinary Habitable Zones in the Presence of a Giant Planet
Frontiers in Astronomy and Space Sciences, 2021 Determining habitable zones in binary star systems can be a challenging task due to the combination of perturbed planetary orbits and varying stellar irradiation conditions.

Palaeoecology of the Hiraiso Formation (Miyagi Prefecture, Japan) and implications for the recovery following the end-Permian mass extinction [PDF]
PeerJ, 2022 The Hiraiso Formation of northeast Japan represents an important and under-explored archive of Early Triassic marine ecosystems. Here, we present a palaeoecological analysis of its benthic faunas in order to explore the temporal and spatial variations of

Neocatastrophism and the milky way astrobiological landscape [PDF]
Serbian Astronomical Journal, 2008 The number and distribution of habitable planets in the Milky Way is one of the foremost problems of contemporary astrobiological research. We investigate the effects of applying general neocatastrophic paradigm to the evolution of the Galactic Habitable

No Transits of Proxima Centauri Planets in High-Cadence TESS Data
Frontiers in Astronomy and Space Sciences, 2021 Proxima Centauri is our nearest stellar neighbor and one of the most well-studied stars in the sky. In 2016, a planetary companion was detected through radial velocity measurements.

The Habitable Zone of Inhabited Planets [PDF]
, 2014 Abstract. In this paper we discuss and illustrate the hypothesis that life substantially alters the state of a planetary environment and therefore, modifies the limits of the HZ as estimated for an uninhabited planet. This hypothesis lead to the introduction of the Habitable Zone for Inhabited Planets (hereafter InHZ), defined here as the region where ...

Inner Habitable Zone Boundary for Eccentric Exoplanets
The Astrophysical Journal Letters, 2023 The climate of a planet can be strongly affected by its eccentricity due to variations in the stellar flux. There are two limits for the dependence of the inner habitable zone boundary (IHZ) on eccentricity: (1) the mean stellar flux approximation ( ${S ...

Tides, planetary companions, and habitability: habitability in the habitable zone of low-mass stars [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 Earth-scale planets in the classical habitable zone (HZ) are more likely to be habitable if they possess active geophysics. Without a constant internal energy source, planets cool as they age, eventually terminating tectonic activity and rendering the planet sterile to life.

ON THE HABITABLE ZONES OF CIRCUMBINARY PLANETARY SYSTEMS [PDF]
The Astrophysical Journal, 2012 The effect of the stellar flux on exoplanetary systems is becoming an increasingly important property as more planets are discovered in the Habitable Zone (HZ). The Kepler mission has recently uncovered circumbinary planets with relatively complex HZs due to the combined flux from the binary host stars.
