The signatures of the parental cluster on field planetary systems

, 2017
Due to the high stellar densities in young clusters, planetary systems formed in these environments are likely to have experienced perturbations from encounters with other stars.

Extra-solar planetary systems [PDF]

Proceedings 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 ...

The ALMA survey to Resolve exoKuiper belt Substructures (ARKS)

Astronomy & Astrophysics
Context. CO gas has been detected in ~20 debris discs, typically classified as CO-poor or CO-rich. We present observations of the CO-rich HD 121617 debris disc as part of the ALMA survey to Resolve exoKuiper belt Substructures (ARKS). Aims.

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

Geosciences, 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.

Microlensing Searches for Exoplanets

Geosciences, 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

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

Serbian 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

Paleo-permeability in oceanic lithosphere inferred from vein mapping along the Wadi Haymiliyah of the Oman Ophiolite

Progress in Earth and Planetary Science
To assess the permeability structure of the oceanic lithosphere, we analyzed the field-based vein distribution and geometry in the Wadi Haymiliyah area of the Oman ophiolite.

Exoplanet Predictions Based on Harmonic Orbit Resonances

Galaxies, 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.
