PhD in Physics & Astronomy: Charge conservation and cloud formation in planet atmospheres (ESR6)
School of Physics and Astronomy
Vacancy Description
School of Physics & Astronomy, Fixed Term: 3.5 years, fully funded, Start: August 2020 PhD entry
As result of formation and evolution processes, exoplanets can have hugely different properties, e.g. giant gas planets, rocky planets, mini-neptunes. Today's best constrained exoplanets are short period, hot Jupiters which show `muted' molecular features, enhanced Rayleigh scattering slopes in the optical, and dynamic features like onsets in the brightest optical emission of the planet. These features arise from a globally circulating and cloud forming atmosphere which is driven by an intense irradiation field from the host star. Both, dynamics and radiation ionise cloud particles. In order to understand the myriad of observational data from present (HST, Spitzer) and future space missions (CHEOPS, JWST, Ariel, PLATO), a thorough understanding of the cloud formation processes is required. The key processes to cloud formation, nucleation and surface growth, will be studied under the effect of ionisation. The effect of ionised particles is essential for cloud formation on Earth but little is known for exoplanets.

This project is part of the Marie Sklodowska-Curie Innovative Training Network (ITN) CHAMELEON “Virtual Laboratories for Exoplanets and Planet Forming Disks”. The ITN combines the expertise of eight European research institutes (Universities of St Andrews, Groningen, Copenhagen, Edinburgh, Leuven and Antwerp, the Max-Planck Institute in Heidelberg and the Netherlands Institute for Space Research) to cover all relevant aspects for this complex modelling task, joining the expertise in planetary atmospheres and protoplanetary disks, including observation and interpretation. For a complete list of all open PhD positions within this training network please visit http://chameleon.wp.st-andrews.ac.uk/

The selected PhD students will be offered a fully funded PhD place at the University of St Andrews’ Centre for Exoplanet Science with training secondment for this position foreseen at the University of Copenhagen, with additional short training at the University of Groningen. The PhD student will receive a double degree from St Andrews and from Copenhagen. The funding will be commensurate to the standard scale for PhD students in according to the Marie-Curie funding rules. The successful PhD applicants will have to register at, and comply with, the regulations of the St Leonard’s Postgraduate College at the University of St Andrews and the rules from the University of Copenhagen. The successful PhD applicants will follow a doctoral programme including personal training in management, science communication, and teaching.

We seek an excellent student with a strong background in physics or astrophysics. Successful candidates must hold a Masters degree or equivalent by the starting date of the position. Previous research experience on planet forming disks and/or astrochemistry, and a track record of team work/mobility will be important criteria for the selection. This is a computational project: some prior knowledge of coding would be useful (e.g., Python and Fortran). Note that the general eligibility and mobility rules of Marie Sklodowka-Curie Actions apply.

Eligibility: CHAMELEON PhD studentships are open to people of any nationality. However, the Marie S. Curie Actions have two strict eligibility criteria for applicants to these positions:

1. EARLY STAGE: The applicant must be within the first four years (full-time equivalent research experience) of her/his research career (starting from the moment you obtain a degree that makes you eligible to study for a PhD) and not have a doctoral degree. Adjustments can be made for career breaks.
2. MOBILITY: The applicant must not have resided or carried out her/his main activity (e.g. work, studies) in the country where she/he has been recruited for more than 12 months in the three years immediately before the recruitment date (this is the day on which you start your PhD).

Further information about eligibility criteria, the application process and the online application form are available at: http://chameleon.wp.st-andrews.ac.uk/recruitment/

Deadline: 3 February 2020

For the first 3 years of employment, as Marie Sklodowska-Curie Fellows, you will receive generous benefits, including a fixed salary/living allowance and mobility/ family allowance HYPERLINK "https://ec.europa.eu/research/participants/data/ref/h2020/wp/2018-
