We explore the response of Titan's surface and massive atmosphere to the change in solar spectrum and intensity as the sun evolves into a red giant. Titan's surface temperature is insensitive to insolation increases as the haze‐laden atmosphere “puffs up” and blocks more sunlight. However, we find a window of several hundred Myr exists, roughly 6 Gyr from now, when liquid water‐ammonia can form oceans on the surface and react with the abundant organic compounds there. The window opens due to a… 
Atmospheric Circulation, Chemistry, and Infrared Spectra of Titan-like Exoplanets around Different Stellar Types
With the discovery of ever smaller and colder exoplanets, terrestrial worlds with hazy atmospheres must be increasingly considered. Our solar system’s Titan is a prototypical hazy planet, whose
The methane cycle on Titan
Despite Titan's cold temperatures (about 93.7 K at the equator), fluvial and atmospheric processes are active on this moon of Saturn, with methane playing a similar role to water on Earth. However,
The origin and evolution of Titan
Titan was formed as a regular satellite in a disk that was the outgrowth of the formation of Saturn itself. Unlike the Jovian system, Titan is alone in terms of its size and mass, notart of a system

TLDR
If icy-organic objects are common in the 20-50 AU zones of these stars, as they are in the authors' Solar System (and as inferred in numerous main sequence stellar disk systems), then DGHZs may form a niche type of habitable zone that is likely to be numerically common inThe Galaxy.
HABITABLE ZONES OF POST-MAIN SEQUENCE STARS
Once a star leaves the main sequence and becomes a red giant, its Habitable Zone (HZ) moves outward, promoting detectable habitable conditions at larger orbital distances. We use a one-dimensional
Biologically enhanced energy and carbon cycling on Titan?
With the Cassini-Huygens Mission in orbit around Saturn, the large moon Titan, with its reducing atmosphere, rich organic chemistry, and heterogeneous surface, moves into the astrobiological
Biosignatures Search in Habitable Planets
The search for life has had a new enthusiastic restart in the last two decades thanks to the large number of new worlds discovered. The about 4100 exoplanets found so far, show a large diversity of
How surfaces shape the climate of habitable exoplanets
Large ground- and space-based telescopes will be able to observe Earth-like planets in the near future. We explore how different planetary surfaces can strongly influence the climate, atmospheric

Habitable moons around extrasolar giant planets
TLDR
It is argued that rocky moons orbiting these companions could be habitable if the planet–moon system orbits the parent star within the so-called 'habitable zone'10, where life-supporting liquid water could be present.

The life span of the biosphere revisited
TLDR
A more elaborate model that includes a more accurate treatment of the greenhouse effect of CO2, a biologically mediated weathering parameterization, and the realization that C4 photosynthesis can persist to much lower concentrations of atmospheric CO2 is found to find that a C4-plant-based biosphere could survive for at least another 0.9 Gyr to 1.5 Gyr after the present time.

TLDR
It is shown that ultraviolet absorption by steady-state amounts of high-altitude organic solids produced from methane photolysis may have shielded ammonia sufficiently that ammonia resupply rates were able to maintain surface temperatures above freezing.
