Habitable Zones in the Universe

, 2005
Habitability varies dramatically with location and time in the universe. This was recognized centuries ago, but it was only in the last few decades that astronomers began to systematize the study of habitability.

Distributions of Long-Lived Radioactive Nuclei Provided by Star Forming Environments [PDF]

, 2015
Radioactive nuclei play an important role in planetary evolution by providing an internal heat source, which affects planetary structure and helps facilitate plate tectonics.

Exomoon habitability constrained by energy flux and orbital stability

, 2012
Detecting massive satellites of extrasolar planets has now become feasible, which led naturally to questions about their habitability. In a previous study we presented constraints on the habitability of moons from stellar and planetary illumination as ...

The Effect of Multiple Heat Sources on Exomoon Habitable Zones [PDF]

, 2017
With dozens of Jovian and super-Jovian exoplanets known to orbit their host stars in or near the stellar habitable zones, it has recently been suggested that moons the size of Mars could offer abundant surface habitats beyond the solar system.

Ion‐Scale Characteristics of the Martian Magnetic Pile‐Up Boundary Layer

Geophysical Research Letters, Volume 52, Issue 3, 16 February 2025.
Abstract The Martian magnetic pile‐up boundary (MPB) delineates the interface between the magnetosheath and the induced magnetosphere, but its global ion‐scale characteristics remaining unclear. Utilizing a three‐dimensional Hall magnetohydrodynamic (MHD) model, this study aims to reveal the features of the MPB layer, including magnetic field, current ...

Evolution of Stellar Activity and Habitable Zone. I. Ultraviolet Emission of Dwarfs in Open Clusters and Field Stars

The Astrophysical Journal Supplement Series
Near-ultraviolet (NUV) radiation from dwarf stars plays a critical role in shaping the habitability of planetary systems, yet its long-term evolution across different spectral types remains poorly investigated.

Implications of the TTV-Detection of Close-In Terrestrial Planets Around M Stars for Their Origin and Dynamical Evolution

, 2010
It has been shown that an Earth-size planet or a super-Earth, in resonance with a transiting Jupiter-like body in a short-period orbit around an M star, can create detectable TTV signals (Kirste \& Haghighipour, 2011). Given the low masses of M stars and

Application of the Titius-Bode Rule to the 55 Cancri System: Tentative Prediction of a Possibly Habitable Planet [PDF]

, 2011
Following the notion that the Titius-Bode rule (TBR) may also be applicable to some extra-solar planetary systems, although this number could be relatively small, it is applied to 55 Cancri, which is a G-type main-sequence star currently known to host ...
