Water vapour in the atmosphere of the habitable-zone eight-Earth-mass planet K2-18 b [PDF]
Nature Astronomy, 2019 In the past decade, observations from space and the ground have found water to be the most abundant molecular species, after hydrogen, in the atmospheres of hot, gaseous extrasolar planets1–5. Being the main molecular carrier of oxygen, water is a tracer

Open Astronomy, 2021 Kaba meteorite as a reference material (one of a least metamorphosed and most primitive carbonaceous chondrites fell on Earth) was chosen for this study providing an adequate background for study of the protoplanetary disk or even the crystallization ...

Ontosonographic Maps: Toward a Theoretization of Soundscape Forms in the Anthropocene Epoch
Etnoantropološki Problemi, 2021 This paper deals with the ways in which it is possible to conceptualize and map forms of soundscape in the epoch of the Anthropocene. After humans became a geological force, which is a role that used to be reserved for the planet itself, one can pose the

Puzzling out the coexistence of terrestrial planets and giant exoplanets. The 2/1 resonant periodic orbits [PDF]
, 2018 Hundreds of giant planets have been discovered so far and the quest of exo-Earths in giant planet systems has become intriguing. In this work, we aim to address the question of the possible long-term coexistence of a terrestrial companion on an orbit ...

Direct Measurement of the Radius and Density of the Transiting Exoplanet HD 189733B with the CHARA Array [PDF]
, 2007 We have measured the angular diameter of the transiting extrasolar planet host star HD 189733 using the CHARA O/IR interferometric array. Combining our new angular diameter of 0.377+/-0.024 mas with the Hipparcos parallax leads to a linear radius for the

Sculpting the valley in the radius distribution of small exoplanets as a by-product of planet formation: the core-powered mass-loss mechanism. [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Recent observations revealed a bimodal radius distribution of small, short-period exoplanets with a paucity in their occurrence, a radius 'valley', around 1.5-2.0 R⊕.

Evolution of Giant Planets in Eccentric Disks [PDF]
, 2006 We investigate the interaction between a giant planet and a viscous circumstellar disk by means of high-resolution, two-dimensional hydrodynamical simulations.

A seven-planet resonant chain in TRAPPIST-1 [PDF]
Nature Astronomy, 2017 The TRAPPIST-1 system is the first transiting planet system found orbiting an ultracool dwarf star1. At least seven planets similar in radius to Earth were previously found to transit this host star2.

Empirical Study of Simulated Two-planet Microlensing Event [PDF]
, 2014 We undertake the first study of two-planet microlensing models recovered from simulations of microlensing events generated by realistic multi-planet systems in which 292 planetary events including 16 two-planet events were detected from 6690 simulated ...
