Accurate Mass Measurements for Planetary Microlensing Events Using High Angular Resolution Observations

open access: yesUniverse, 2018
The microlensing technique is a unique method to hunt for cold planets over a range of mass and separation, orbiting all varieties of host stars in the disk of our galaxy.

A Quantitative Comparison of Exoplanet Catalogs

open access: yesGeosciences, 2018
In this study, we investigated the differences between four commonly-used exoplanet catalogs (exoplanet.eu; exoplanetarchive.ipac.caltech.edu; openexoplanetcatalogue.com; exoplanets.org) using a Kolmogorov–Smirnov (KS) test.

Observations and modeling of the transiting exoplanets XO-2b, HAT-P-18b, and WASP-80b [PDF]

open access: yesSerbian Astronomical Journal, 2017
We present photometric observations and transit solutions of the exoplanets XO-2b, HAT-P-18b and WASP 80b. Our solution of the XO-2b transit gave system parameters whose values are close to those of the previous studies. The solutions of the new

A Review on Substellar Objects below the Deuterium Burning Mass Limit: Planets, Brown Dwarfs or What?

open access: yesGeosciences, 2018
“Free-floating, non-deuterium-burning, substellar objects” are isolated bodies of a few Jupiter masses found in very young open clusters and associations, nearby young moving groups, and in the immediate vicinity of the Sun.

Extra-solar planetary systems [PDF]

open access: yesProceedings of the National Academy of Sciences, 1999
The discovery of extra-solar planets has captured the imagination and interest of the public and scientific communities alike, and for the same reasons: we are all want to know the answers to questions such as “Where do we come from?” and “Are we alone?” Throughout this century, popular culture has presumed the existence of other worlds and extra ...

Microlensing Searches for Exoplanets

open access: yesGeosciences, 2018
Gravitational microlensing finds planets through their gravitational influence on the light coming from a more distant background star. The presence of the planet is then inferred from the tell-tale brightness variations of the background star during the

Exoplanet Predictions Based on Harmonic Orbit Resonances

open access: yesGalaxies, 2017
The current exoplanet database includes 5454 confirmed and candidate planets observed with the Kepler mission. We find 932 planet pairs from which we extract distance and orbital period ratios.

Paleo‐Permeability Structure of the Crustal Section of the Samail Ophiolite Based on Automated Detection of Veins in X‐Ray CT Core Images From the Oman Drilling Project

open access: yesGeochemistry, Geophysics, Geosystems, 2023
To assess the paleo‐permeability structure of oceanic crust, we used 3‐D X‐ray Computed Tomography (XCT) images to quantify the distribution and geometry of mineral veins in core samples from Oman Drilling Project Holes GT1A, GT2A, and GT3A, which ...

DIVISION III: PLANETARY SYSTEMS SCIENCE [PDF]

open access: yesProceedings of the International Astronomical Union, 2008
The meeting was opened by Ted Bowell, president, at 11 am. The 2006 Division III meetings were reviewed by Guy Consolmagno, secretary; as the minutes of those meetings have already been published, they were assumed to be approved.
