As a contribution to the study of the habitability of extrasolar planets, we implemented a one-dimensional energy balance model (EBM), the simplest seasonal model of planetary climate, with new prescriptions for most physical quantities. Here we apply our EBM to investigate the surface habitability of planets with an Earth-like atmospheric composition but different levels of surface pressure. The habitability, defined as the mean fraction of the planet's surface on which liquid water could… 

MODELING THE SURFACE TEMPERATURE OF EARTH-LIKE PLANETS

We introduce a novel Earth-like planet surface temperature model (ESTM) for habitability studies based on the spatial–temporal distribution of planetary surface temperatures. The ESTM adopts a

The Effect of Varying Atmospheric Pressure upon Habitability and Biosignatures of Earth-like Planets.

The aim of the present study is to understand the influence of atmospheric mass on climate, hence habitability, and the spectral appearance of planets with Earth-like atmospheres orbiting the Sun at 1 AU, using a 1D coupled, cloud-free, climate-photochemical atmospheric column model.

Dynamical Effects on the Habitable Zone for Earth-like Exomoons

With the detection of extrasolar moons (exomoons) on the horizon, it is important to consider their potential for habitability. If we consider the circum stellar Habitable Zone (HZ, often described

Atmospheric Dynamics on Terrestrial Planets: The Seasonal Response to Changes in Orbital, Rotational, and Radiative Timescales

Thousands of exoplanets have been detected to date, and with future planned missions this tally will increase. Understanding the climate dependence on the planetary parameters is vital for the study

The influence of surface CO2 condensation on the evolution of warm and cold rocky planets orbiting Sun-like stars

The habitable zone is the region around a star where standing bodies of liquid water can be stable on a planetary surface. Its width is often assumed to be dictated by the efficiency of the

A simple evolutional model of Habitable Zone around host stars with various mass and low metallicity

Habitable Zone (HZ) is defined as a life existence area, where water at the surface of the terrestrial planet is in liquid phase. This is caused by the balance of flux from the host star and

Quantitative estimates of the surface habitability of Kepler-452b

Kepler-452b is currently the best example of an Earth-size planet in the habitable zone of a sun-like star, a type of planet whose number of detections is expected to increase in the future.

The effect of high nitrogen pressures on the habitable zone and an appraisal of greenhouse states

The habitable zone is the main tool that mission architectures utilize to select potentially habitable planets for follow up spectroscopic observation. Given its importance, the precise size and

TOWARD THE MINIMUM INNER EDGE DISTANCE OF THE HABITABLE ZONE

We explore the minimum distance from a host star where an exoplanet could potentially be habitable in order not to discard close-in rocky exoplanets for follow-up observations. We find that the inner

HABITABLE CLIMATES: THE INFLUENCE OF ECCENTRICITY

In the outer regions of the habitable zone, the risk of transitioning into a globally frozen “snowball” state poses a threat to the habitability of planets with the capacity to host water-based life.

The results suggest that mid-to-early K stars should be considered along with G stars as optimal candidates in the search for extraterrestrial life.

HABITABLE CLIMATES: THE INFLUENCE OF OBLIQUITY

Extrasolar terrestrial planets with the potential to host life might have large obliquities or be subject to strong obliquity variations. We revisit the habitability of oblique planets with an energy

According to the standard liquid-water definition, the Earth is only partially habitable. We reconsider planetary habitability in the framework of energy balance models, the simplest seasonal models

We show that collision-induced absorption allows molecular hydrogen to act as an incondensible greenhouse gas and that bars or tens of bars of primordial H2–He mixtures can maintain surface
