Volatile-rich Earth-Mass Planets in the Habitable Zone [PDF]
, 2003 A small planet is not necessarily a terrestrial planet. Planets that form beyond the snow line with too little mass to seed rapid gas accretion (≲10 M⊕) should be rich in volatile ices like H2O and NH3.

Habitable zone lifetimes of exoplanets around main sequence stars.
Astrobiology, 2013 The potential habitability of newly discovered exoplanets is initially assessed by determining whether their orbits fall within the circumstellar habitable zone of their star.

Long-term Stability of Tightly Packed Multi-planet Systems in Prograde, Coplanar, Circumstellar Orbits within the α Centauri AB System [PDF]
, 2018 We perform long-term simulations, up to ten billion years, of closely spaced configurations of 2–6 planets, each as massive as the Earth, traveling on nested orbits about either stellar component in α Centauri AB. The innermost planet initially orbits at

Dynamics and habitability in circumstellar planetary systems of known binary stars [PDF]
, 2016 We present a survey on exoplanetary systems of binary stars with stellar separations less than 100 au. For a sample of 11 binaries that harbour detected circumstellar giant planets we investigate the frequency of systems with secular resonances (SR ...

Habitable zones with stable orbits for planets around binary systems [PDF]
, 2014 A general formulation to compute habitable zones (HZ) around binary stars is presented. A HZ in this context must satisfy two separate conditions: a radiative one and one of dynamical stability.

The Galactic Habitable Zone: Galactic Chemical Evolution
, 2001 We propose the concept of a “Galactic Habitable Zone” (GHZ). Analogous to the Circumstellar Habitable Zone (CHZ), the GHZ is that region in the Milky Way where an Earth-like planet can retain liquid water on its surface and provide a long-term habitat ...

Circumstellar Dust Created by Terrestrial Planet Formation in HD 113766 [PDF]
, 2007 We present an analysis of the gas-poor circumstellar material in the HD 113766 binary system (F3/F5, 10-16 Myr), recently observed by the Spitzer Space Telescope. For our study we have used the IR mineralogical model derived from observations of the Deep

How wide is the Goldilocks Zone in your health system?
Journal of Health Services Research and Policy, 2018 In astrophysics, the ‘Goldilocks Zone’ describes the circumstellar habitable zone, in which planets, sufficiently similar to Earth, could support human life.

Generic data reduction for nulling interferometry package: the grip of a single data reduction package on all the nulling interferometers [PDF]
Astronomical Telescopes + InstrumentationNulling interferometry is a powerful observing technique to reach exoplanets and circumstellar dust at separations too small for direct imaging with single-dish telescopes and too large for indirect methods. With near-future instrumentation, it bears the
