NGTS-4b: A sub-Neptune transiting in the desert

CEH member Richard West leads the fascinating discovery of an exoplanet that falls in the middle of what has been termed the 'Neptunian desert'. This refers to a region close-in to the parent star where previously no Neptune-sized exoplanets had been found. NGTS-4b has a mass 20 times that of the Earth and orbits its star (a 13th mag K dwarf) once every 1.34 days! What's more, it's the smallest planet discovered by a wide-field ground-based photometric survey to date - excellent work!

This study was published in Monthly Notices of the Royal Astronomical Society, Volume 486, Issue 4, July 2019, Pages 5094–5103

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.

University Research Centre

As of the 28th of June 2017, the Centre for Exoplanets and Habitability has been established as a University of Warwick Research Centre. Thank you to all members of the CEH who have contributed to our work so far, and who helped to make this a reality.
