The Formation of the Kepler-10 Planetary System

The Formation of the Kepler-10 Planetary System

In this paper, we investigate the conditions required for the 3 and 17 Earth mass solid planets in the Kepler-10 system to have formed through collisions and mergers within an initial population of embryos.

Probing the Terrestrial Regions of Planetary Systems: Warm Debris Disks with Emission Features

Probing the Terrestrial Regions of Planetary Systems: Warm Debris Disks with Emission Features

Observations of debris disks allow for the study of planetary systems, even where planets have not been detected.

Searching for Earth-mass planets around α Centauri

Searching for Earth-mass planets around α Centauri

This work is part of an ongoing project which aims to detect terrestrial planets in our neighbouring star system α Centauri using the Doppler method.

Astronomers come up dry in search for water on exoplanets

Astronomers come up dry in search for water on exoplanets

A team of astronomers has made the most precise measurements yet of water vapour in the atmospheres of Jupiter-like planets beyond our Solar System and found them to be much drier worlds than expected.

Four billion-year-old chemistry in cells today

Four billion-year-old chemistry in cells today

Parts of the primordial soup in which life arose have been maintained in our cells today according to scientists at the University of East Anglia.

Atmospheric dynamics of terrestrial exoplanets over a wide range of orbital and atmospheric parameters

Atmospheric dynamics of terrestrial exoplanets over a wide range of orbital and atmospheric parameters

The recent discoveries of terrestrial exoplanets and super Earths extending over a broad range of orbital and physical parameters suggests that these planets will span a wide range of climatic regimes.

H2O abundances in the atmospheres of three hot Jupiters

H2O abundances in the atmospheres of three hot Jupiters

The core accretion theory for giant planet formation predicts enrichment of elemental abundances in planetary envelopes caused by runaway accretion of planetesimals, which is consistent with measured super-solar abundances of C, N, P, S, Xe, and Ar in Jupiter's atmosphere.

A New Approach to SETI: Targeting Alien Polluters

A New Approach to SETI: Targeting Alien Polluters

Humanity is on the threshold of being able to detect signs of alien life on other worlds. By studying exoplanet atmospheres, we can look for gases like oxygen and methane that only coexist if replenished by life.

Direct Imaging of Exoplanets in the Habitable Zone with Adaptive Optics

Direct Imaging of Exoplanets in the Habitable Zone with Adaptive Optics

One of the primary goals of exoplanet science is to find and characterize habitable planets, and direct imaging will play a key role in this effort.
