O2- and CO-rich Atmospheres for Potentially Habitable Environments on TRAPPIST-1 Planets [PDF]
Astrophysical Journal, 2019 Small exoplanets of nearby M-dwarf stars present the possibility of finding and characterizing habitable worlds within the next decade. TRAPPIST-1, an ultracool M-dwarf star, was recently found to have seven Earth-sized planets of predominantly rocky ...

Developing ecospheres on transiently habitable planets: the genesis project [PDF]
, 2016 It is often presumed, that life evolves relatively fast on planets with clement conditions, at least in its basic forms, and that extended periods of habitability are subsequently needed for the evolution of higher life forms.

Water delivery by pebble accretion to rocky planets in habitable zones in evolving disks [PDF]
Astronomy & Astrophysics, 2019 Context. The ocean mass of the Earth is only 2.3 × 10−4 of the whole planet mass. Even including water in the interior, the water fraction would be at most 10−3−10−2. Ancient Mars may have had a similar or slightly smaller water fraction. What controlled

On the probability of habitable planets [PDF]
International Journal of Astrobiology, 2013 AbstractIn the past 15 years, astronomers have revealed that a significant fraction of the stars should harbour planets and that it is likely that terrestrial planets are abundant in our galaxy. Among these planets, how many are habitable, i.e. suitable for life and its evolution?

Spatial and temporal dynamics of aufeis in the Tso Moriri basin, eastern Ladakh, India
Permafrost and Periglacial Processes, Volume 34, Issue 1, Page 81-93, January/March 2023., 2023 Abstract Aufeis is a common phenomenon in cold regions of the Northern Hemisphere that develops during winter by successive water overflow and freezing on ice‐covered surfaces. Most studies on aufeis occurrence focus on regions in North America and Siberia, while research in High Mountain Asia (HMA) is still in an exploratory phase.

The Impact of Stripped Cores on the Frequency of Earth-size Planets in the Habitable Zone [PDF]
Astrophysical Journal, 2019 The frequency of Earth-size planets in the habitable zone (HZ) of Sun-like stars, hereafter η⊕, is a key parameter to evaluate the yield of nearby Earth analogs that can be detected and characterized by future missions.

No Snowball on Habitable Tidally Locked Planets with a Dynamic Ocean [PDF]
Astrophysical Journal, 2019 Terrestrial planets orbiting within the habitable zones of M-stars are likely to become tidally locked in a 1:1 spin:orbit configuration and are prime targets for future characterization efforts.

A Maximum Radius for Habitable Planets [PDF]
Origins of Life and Evolution of Biospheres, 2015 We compute the maximum radius a planet can have in order to fulfill two constraints that are likely necessary conditions for habitability: 1- surface temperature and pressure compatible with the existence of liquid water, and 2- no ice layer at the bottom of a putative global ocean, that would prevent the operation of the geologic carbon cycle to ...

Inner Edge of Habitable Zones for Earth‐Sized Planets With Various Surface Water Distributions [PDF]
Journal of Geophysical Research: Planets, 2019 When planets receive insolation above a certain critical value called the runaway threshold, liquid surface water vaporizes completely, which forms the inner edge of the habitable zone.
