Pondering panspermia - how life could travel through space

James Blake, a postgraduate student in the Warwick Astronomy & Astrophysics Group, gives an overview of his summer project researching the topic of panspermia and applying the theory to the exciting TRAPPIST-1 planetary system.


Dynamical and Biological Panspermia Constraints Within Multiplanet Exosystems

Dimitri Veras leads an interdisciplinary team of astronomers and biologists in a study exploring the dynamical and biological constraints of interplanetary panspermia. This is the theory that life can hop from planet to planet via some mechanism, most likely aboard asteroids or comets.

Ground-based detection of G star superflares with NGTS

CEH member James Jackman leads a recent study of flares in G-type stars, as observed using NGTS. The study shows that G-stars can have flares many times the energy of the Carrington event, and the primary detection is one of the largest amplitude superflares detected from a bright G star.

Automatic vetting of planet candidates from ground based surveys: Machine learning with NGTS

CEH member David Armstrong has published a new study on automatic vetting of exoplanet candidates using machine learning techniques. In this work he applies it to candidates from NGTS, but the technique is extendable to other transiting exoplanet surveys.

The XUV environments of exoplanets from Jupiter-size to super-Earth

CEH member George King has published an exciting study looking at the extreme UV environment of several exoplanets, including a detection of the transit of WASP-80b in the NUV using XMM Newton.

The study was published in Monthly Notices of the Royal Astronomical Society, Volume 478, Issue 1, July 2018, Pages 1193–1208
