Understanding how unusual Earth is may help humanity to appreciate how special it is.

August 2019: More than 4100 planets are known to orbit stars far beyond the solar system, in planetary systems very different to our own. There may well be hundreds of billions of extrasolar planets in the Milky Way alone. These planets include planetary types not found among the eight planets that orbit our Sun, including mini-Neptunes, super-Earths, rogue or nomad planets and hot gas-giant planets. Are we therefore alone in the Universe? To answer this pertinent question, we seek to understand the formation and evolution of our own solar system and the reasons for this rich planetary diversity.

The Centre for Exoplanet Science brings together researchers from different disciplines to find out how planets form in different galactic environments, how their atmospheres evolve, and the relation between the evolutionary history of planets and the emergence of life. We are further interested in the moral, ethical and technical aspects of detecting existent or extinct extra-terrestrial life in distant exosystems, or within our own solar system, and the significance of such a discovery for our societies.

The Centre for Exoplanet Science builds on the rich legacy of the SUPA Astrobiology initiative.

The Centre for Exoplanet Science currently combines research from the School of Physics & Astronomy (Astronomy), the School of Earth and Environmental Sciences, the Department of Philosophy, the School of Biology and the Department of Social Anthropology at the University of St Andrews.

We are collaborating with the   Centre for Exoplanet Science   at the University of Edinburgh.


Lunch time meetings in Spring 2020

We will have four lunch time meetings planned for our Centre for Exoplanet Science in spring 2020:
3 February 2020, 13-14:00h:   "Sci-Fi planet(s)"
Introduce a Sci-Fi planet! Do most SciFi authors have a narrow, Earth-centric view on exoplanets? Are their planets as biodiverse as our Earth?
2 March 2020, 13-14:00:   "The Inverse Problem"
27 April 2020, 13-14:00h, Gateway Boardroom
18 May 2020, 13-14:00h, Gateway Boardroom
All meetings will take place in the Gateway Boardroom, North Haugh, 13-14:00h. Catering will be provied. You are all very welcome to join us.


"Geology determines the outer edge of the Habitable Zone"

Seminar talk at the School of Earth & Environmental Sciences.

Speaker: Prof Raymond Pierrehumbert, University of Oxford
Wednesday 15 Apr 2020:  13:00h,  Forbes Room, 2nd floor, Irvine Building.
Refreshments are provided from 12:30h in the Forbes Room for the purpose of social mingling. All are welcome!

CHAMELEON   'Virtual Laboratories for Exoplanets and Planet-Forming Disks'   (Marie Curie Innovative Training Network)

The Centre for Exoplanet Science invites applications for 15 PhD places as part of the Marie Curie Innovative Training Network project CHAMELEON 'Virtual Laboratories for Exoplanets and Planet-Forming Disks'  for double-degrees involving the universities of St Andrews, Antwerp, Copenhagen, Edinburgh, Groningen and Leuven, as well as SRON/Utrecht and MPIA/Heidelberg.

‣  ESR3:  "Cloud formation in 3D exoplanet atmospheres"
‣  ESR5:  "Microphysics of cloud formation: The path to heterogeneous nucleation"
‣  ESR6:  "Charge conservation and cloud formation in planet atmospheres"
‣  ESR7:  "Grain charges and lightning in disks"
‣  ESR8:  "The warm chemistry in the inner disk"
‣  ESR9:  "Machine learning from complex disk models"

Details about the projects and the required application material can be found on the CHAMELEON webpage.
Note that the deadlines vary from December 2019 to February 2020.

The Scottish Exoplanet / Brown Dwarf Spring Meeting 2020 will be held on 28 April 2020 at the University of St Andrews, Gateway Seminar Room 3, starting at 10:30h, and concluding at 17:00h. Doors open at 10:00h.
In this meeting we want to facilitate discussions and collaborations between Scotland-based exoplanet and brown dwarf researchers, and want to provide a platform for junior community members to present results.
Registration deadline: 16 February 2020.
There is no registration fee. Coffee and lunch will be provided.

To celebrate the 10th of our SEBD events, we are announcing a SEBD logo competition. Get creative! — Submit your logo suggestion to us by 30 March 2020. We then will invite the SEBD community to vote for the SEBD logo and the winner will be announced during the meeting on 28 April 2020 in St Andrews. Looking forward to your submissions!
