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.

EPJ Web of Conferences, 2013 The exquisite photometric precision of the Kepler space telescope now puts the detection of extrasolar moons at the horizon. Here, we firstly review observational and analytical techniques that have recently been proposed to find exomoons.

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.

On the origin and evolution of life in the Galaxy [PDF]
, 2010 A simple stochastic model for evolution, based upon the need to pass a sequence of n critical steps is applied to both terrestrial and extraterrestrial origins of life. In the former case, the time at which humans have emerged during the habitable period

The habitable zone for Earth-like exomoons orbiting Kepler-1625b [PDF]
, 2019 The recent announcement of a Neptune-sized exomoon candidate orbiting the Jupiter-sized object Kepler-1625b has forced us to rethink our assumptions regarding both exomoons and their host exoplanets.

GJ 832c: A SUPER-EARTH IN THE HABITABLE ZONE [PDF]
The Astrophysical Journal, 2014 We report the detection of GJ 832c, a super-Earth orbiting near the inner edge of the habitable zone of GJ 832, an M dwarf previously known to host a Jupiter analog in a nearly-circular 9.4-year orbit. The combination of precise radial-velocity measurements from three telescopes reveals the presence of a planet with a period of 35.68+/-0.03 days and ...

A Limited Habitable Zone for Complex Life [PDF]
, 2019 The habitable zone (HZ) is commonly defined as the range of distances from a host star within which liquid water, a key requirement for life, may exist on a planet's surface. Substantially more CO2 than present in Earth's modern atmosphere is required to
