PG module - Habitability in the Universe

The Centre for Exoplanets and Habitability convenes a Postgraduate module, "Habitability in the Universe", which is run by the Institute for Advance Teaching and Learning. This module is open to all postgraduates, from all disciplines, and covers the subject of habitability from myriad perspectives. More details can be found on the module's home page.


Welcome

Welcome to the website of the Centre for Exoplanets and Habitability (CEH) at the University of Warwick. The CEH is a cross-disciplinary research centre that draws upon expertise from departments across the university. It is a collaborative project which works with both the sciences and arts in order to consider life beyond, and on, this planet. We are a newly formed University Research Centre looking for funding to develop our research goals. Please explore our webpages, and feel free to contact us if you would like to get involved.


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

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.
