Circumstellar Habitable Zones of Binary Star Systems in the Solar Neighborhood
, 2012 Binary and multiple systems constitute more than half of the total stellar population in the Solar neighborhood (Kiseleva-Eggleton and Eggleton 2001). Their frequent occurrence as well as the fact that more than 70 (Schneider et al.

The Depositional Record, EarlyView.Emblematic of global coral‐reef ecosystem decline, the coral ecosystem‐engineer Acropora palmata is now rare throughout much of the western Atlantic. We report for the first time, a significant record of late‐Holocene A. palmata populations that existed from ~4500 to 375 years before present in the Dry Tortugas, FL, USA.

How common are habitable planets? [PDF]
Nature, 1999 The Earth is teeming with life, which occupies a diverse array of environments; other bodies in our Solar System offer fewer, if any, niches that are habitable by life as we know it. Nonetheless, astronomical studies suggest that many habitable planets may be present within our Galaxy.

VALIDATION OF 12 SMALL KEPLER TRANSITING PLANETS IN THE HABITABLE ZONE [PDF]
, 2015 We present an investigation of 12 candidate transiting planets from Kepler with orbital periods ranging from 34 to 207 days, selected from initial indications that they are small and potentially in the habitable zone (HZ) of their parent stars.

Tides and the Evolution of Planetary Habitability
, 2008 Tides raised on a planet by its host star's gravity can reduce a planet's orbital semi-major axis and eccentricity. This effect is only relevant for planets orbiting very close to their host stars.

THE SNOW LINE IN VISCOUS DISKS AROUND LOW-MASS STARS: IMPLICATIONS FOR WATER DELIVERY TO TERRESTRIAL PLANETS IN THE HABITABLE ZONE [PDF]
, 2015 The water-ice or snow line is one of the key properties of protoplanetary disks that determines the water content of terrestrial planets in the habitable zone.

Hydrohalite Salt-albedo Feedback Could Cool M-dwarf Planets
, 2018 A possible surface type that may form in the environments of M-dwarf planets is sodium chloride dihydrate, or "hydrohalite" (NaCl $\cdot$ 2H$_2$O), which can precipitate in bare sea ice at low temperatures.

THE ROLE OF PLATE TECTONIC–CLIMATE COUPLING AND EXPOSED LAND AREA IN THE DEVELOPMENT OF HABITABLE CLIMATES ON ROCKY PLANETS [PDF]
, 2015 The long-term carbon cycle is vital for maintaining liquid water oceans on rocky planets due to the negative climate feedbacks involved in silicate weathering.

Case Studies of Habitable Trojan Planets in the System of HD 23079
, 2011 We investigate the possibility of habitable Trojan planets in the HD 23079 star-planet system. This system consists of a solar-type star and a Jupiter-type planet, which orbits the star near the outer edge of the stellar habitable zone in an orbit of low
