Effects of Extreme Obliquity Variations on the Habitability of Exoplanets [PDF]

, 2014
We explore the impact of obliquity variations on planetary habitability in hypothetical systems with high mutual inclination. We show that large amplitude, high frequency obliquity oscillations on Earth-like exoplanets can suppress the ice-albedo ...

The Impact of Stellar Distances on Habitable Zone Planets [PDF]

Astrophysical Journal, 2018
Among the most highly valued of exoplanetary discoveries are those of terrestrial planets found to reside within the habitable zone (HZ) of the host star.

Exploring Kepler Giant Planets in the Habitable Zone [PDF]

Astrophysical Journal, 2018
The Kepler mission found hundreds of planet candidates within the Habitable Zones (HZ) of their host star, including over 70 candidates with radii larger than three Earth radii (R⊕) within the optimistic HZ (OHZ).

Habitability Properties of Circumbinary Planets [PDF]

The Astronomical Journal, 2017
Abstract It is shown that several habitability conditions (in fact, at least seven such conditions) appear to be fulfilled automatically by circumbinary planets of main-sequence stars (CBP-MS), whereas on Earth, these conditions are fulfilled only by chance.

Constraints on alternate universes: stars and habitable planets with different fundamental constants [PDF]

, 2015
This paper develops constraints on the values of the fundamental constants that allow universes to be habitable. We focus on the fine structure constant α and the gravitational structure constant αG, and find the region in the α-αG plane that supports ...

A satellite perspective on the movement decisions of African elephants in relation to nomadic pastoralists

Remote Sensing in Ecology and Conservation, Volume 8, Issue 6, Page 841-854, December 2022., 2022
The African savannah ecosystem is populated by nomadic pastoralists who corral livestock at night in temporary enclosures, called bomas, to protect them. The number and distribution of bomas in the savannah is important from an ecological perspective. However, no studies have yet examined the spatial‐temporal dynamics of bomas and their relationship to

Colliding Winds in Low-Mass Binary Star Systems: wind interactions and implications for habitable planets [PDF]

, 2015
Context. In binary star systems, the winds from the two components impact each other, leading to strong shocks and regions of enhanced density and temperature.

Planetary Dynamics and Habitable Planet Formation In Binary Star Systems

, 2009
Whether binaries can harbor potentially habitable planets depends on several factors including the physical properties and the orbital characteristics of the binary system.

Hot Moons and Cool Stars

, 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.

Around seven decades river course shifting and bank erosion susceptibility of river Mujnai

River, Volume 1, Issue 2, Page 221-239, November 2022., 2022
Abstract River bank erosion is a destructive fluvio‐hydrological hazard particularly inhabited flood plain of the dynamic Himalayan foreland basin. Every year during monsoonal months, morphology of the landscape is continuously modifying through the dynamic river system.
