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.

Carbonate clumped isotope thermometry of fault rocks and its possibilities: tectonic implications from calcites within Himalayan Frontal Fold-Thrust Belt

open access: yesProgress in Earth and Planetary Science, 2021
Disentangling the temperature and depth of formation of fault rocks is critical for understanding their rheology, exhumation, and the evolution of fault zones.

Unstable low-mass planetary systems as drivers of white dwarf pollution [PDF]

open access: yes, 2017
At least 25 percent of white dwarfs show atmospheric pollution by metals, sometimes accompanied by detectable circumstellar dust/gas discs or (in the case of WD 1145+017) transiting disintegrating asteroids.

A natural formation scenario for misaligned and short-period eccentric extrasolar planets [PDF]

open access: yes, 2011
Recent discoveries of strongly misaligned transiting exoplanets pose a challenge to the established planet formation theory which assumes planetary systems to form and evolve in isolation.

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

Effects of unseen additional planetary perturbers on compact extrasolar planetary systems [PDF]

open access: yes, 2017
Motivated by the large number of compact extrasolar planetary systems discovered by the Kepler Mission, this paper considers perturbations due to possible additional outer planets.

Architecture of Kepler's Multi-transiting Systems: II. New investigations with twice as many candidates [PDF]

open access: yes, 2014
We report on the orbital architectures of Kepler systems having multiple planet candidates identified in the analysis of data from the first six quarters of Kepler data and reported by Batalha et al. (2013).

Characterizing K2 Candidate Planetary Systems Orbiting Low-mass Stars. II. Planetary Systems Observed During Campaigns 1–7 [PDF]

open access: yes, 2017
We recently used near-infrared spectroscopy to improve the characterization of 76 low-mass stars around which K2 had detected 79 candidate transiting planets. 29 of these worlds were new discoveries that had not previously been published.

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 ...
