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

The ultraviolet habitable zone of exoplanets
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT The dozens of rocky exoplanets discovered in the circumstellar habitable zone (CHZ) currently represent the most suitable places to host life as we know it outside the Solar system. However, the presumed presence of liquid water on the CHZ planets does not guarantee suitable environments for the emergence of life.

Analyzing the Habitable Zones of Circumbinary Planets Using Machine Learning [PDF]
The Astrophysical Journal, 929:187 (8pp), 2022 April 20, 2021 Exoplanet detection in the past decade by efforts including NASA's Kepler and TESS missions has discovered many worlds that differ substantially from planets in our own Solar System, including more than 150 exoplanets orbiting binary or multi-star systems.

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

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 ...

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.

Exomoons in the Habitable Zones of M Dwarfs [PDF]
The Astrophysical Journal, 2019 Abstract M dwarfs host most of the exoplanets in the local Milky Way. Some of these planets, ranging from sub-Earths to super-Jupiters, orbit in their stars’ habitable zones (HZs), although many likely possess surface environments that preclude habitability.

On the timescale forcing in astrobiology [PDF]
Serbian Astronomical Journal, 2007 We investigate the effects of correlated global regulation mechanisms, especially Galactic gamma-ray bursts (GRBs), on the temporal distribution of hypothetical inhabited planets, using simple Monte Carlo numerical experiments.
