Spatial Big Data Organization, Access and Visualization with ESSG [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
There are hundreds of spatial reference frame (SRF) being applied, and the great difference among SRFs has blocked the share of global data on planet Earth.

The first super-Earth Detection from the High Cadence and High Radial Velocity Precision Dharma Planet Survey [PDF]

, 2018
The Dharma Planet Survey (DPS) aims to monitor about 150 nearby very bright FGKM dwarfs (within 50 pc) during 2016$-$2020 for low-mass planet detection and characterization using the TOU very high resolution optical spectrograph (R$\approx$100,000, 380 ...

Dynamic Landslide Susceptibility Assessment in the Yalong River Alpine Gorge Region Integrating InSAR-Derived Deformation Velocity

Remote Sensing
Dynamic susceptibility assessment is essential for mitigating evolving landslide risks in alpine gorge regions. To address the static limitations and unit mismatch issues in conventional landslide susceptibility assessments in alpine gorge regions, this ...

Fast Rise of "Neptune-Size" Planets ($4-8 R_{\rm Earth}$) from $P\sim10$ to $\sim250$ days -- Statistics of Kepler Planet Candidates Up to $\sim 0.75 {\rm AU}$

, 2013
We infer the period ($P$) and size ($R_p$) distribution of Kepler transiting planet candidates with $R_p\ge 1 R_{\rm Earth}$ and $P < 250$ days hosted by solar-type stars.

Tracing the ingredients for a habitable earth from interstellar space through planet formation [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 2015
Significance With the rapid pace at which exoplanets are being discovered, many efforts have now been dedicated to identifying which planets are expected to have the ingredients necessary for the development of life.

HUMANIZING THE EARTH AND A POSSIBLE STRATEGY TO PREVENT A POSSIBLE DISASTER [PDF]

Annals: Series on Military Sciences, 2013
Earth is both a planet, a resource and an effect. A planet on which life is possible and a resource resumed from a cosmic and geophysical effect that sustains life. At the same time, the earth - as the planet of people is becoming more and more a product

The Hunt for Exomoons with Kepler (HEK): III. The First Search for an Exomoon around a Habitable-Zone Planet

, 2013
Kepler-22b is the first transiting planet to have been detected in the habitable-zone of its host star. At 2.4 Earth radii, Kepler-22b is too large to be considered an Earth-analog, but should the planet host a moon large enough to maintain an atmosphere,

GJ 357 d: Potentially Habitable World or Agent of Chaos?

The Astronomical Journal, 2023
Multiplanet systems provide important laboratories for exploring dynamical interactions within the range of known exoplanetary system architectures. One such system is GJ 357, consisting of a low-mass host star and three orbiting planets, the outermost ...

A super-Earth-sized planet orbiting in or near the habitable zone around Sun-like star

, 2013
We present the discovery of a super-earth-sized planet in or near the habitable zone of a sun-like star. The host is Kepler-69, a 13.7 mag G4V-type star.
