Research Activity

In Space and Planetary Physics, we study the physics of space plasmas, from the Sun, through interplanetary space to the atmospheres of Earth, other planets, their rings and moons.

Our research probes the fundamental physics that underpins the space environment of the Solar System. We also conduct planetary physics research that investigates the interiors, origins and evolution of solar system bodies. To carry out this research, we use state of the art instrumentation on a variety of spacecraft located around the solar system, from the Hubble Space Telescope at Earth, to MAVEN at Mars, and Cassini at Saturn. We are also involved in future space missions, including missions to Jupiter such as the Juno mission (arriving 2016) and the European Space Agency’s JUICE mission to Jupiter coming in 2030, and in developing ideas for future space missions. Our observational work is complemented with computer modelling using a range of models, from bespoke software to internationally-developed numerical models.

Our research into Earth's space environment uses a range of ground- and space-based instrumentation. Measurements by the Cluster, THEMIS and MMS spacecraft allow us to probe the solar-terrestrial interaction in situ. Observations by ground-based magnetometers and ionospheric radars such as the Super Dual Auroral Radar Network (SuperDARN) provide an invaluable remote sensing capability. As part of this effort, Lancaster space physicists develop and deploy state-of-the-art experiments in the UK and inside the Arctic and Antarctic circles.”

We research space weather to investigate the mechanisms by which the Sun controls near-Earth space to understand better the risks posed to high-tech infrastructure both on and above the surface of our planet. We also run the AuroraWatch service which provides forecasts of displays of the northern lights over the UK.

  • Physics of Jupiter’s Magnetosphere and Planetary Environment

     

    Supervisor

    Dr Chris Arridge

    Description

    The magnetospheres of the giant planets are influenced by planetary ring systems and natural satellites, populations of dust, neutral gas, plasma, and radiation belts, and the host planet’s atmosphere, all embedded within the supersonic solar wind. The challenge of unravelling how these elements interact, and what physical processes are at work has been studied for over 40 years using spacecraft and ground-based observatories. Most recently, the Cassini-Huygens mission at Saturn/Titan, and the Juno mission at Jupiter have been providing data to answer these questions. The challenges of understanding these systems include processing and comparing 100s of GB of data; accounting for sampling, resolution and other instrumental biases; and inferring the state of processes in large-scale systems with limited spacecraft trajectories. In this project, the physics of Jupiter’s magnetosphere will be investigated using data from previous space missions (e.g., Galileo), numerical models, remote observations of the Aurora, and new data from Juno. The project will involve applying techniques from data science, such as machine learning, clustering, modelling, and statistical inference.

    Funding is available on a competitive basis. Interested candidates should contact Dr Chris Arridge (c.arridge@lancaster.ac.uk) for further information. Applicants are normally expected to have the equivalent of a first (1) or upper second class (2.1) degree in Physics, Astrophysics or a related discipline.

  • Dynamics of Jupiter’s magnetosphere and Aurora

     

    Supervisor

    Dr Sarah Badman

    Description

    We are entering a new era of understanding of giant planet environments thanks to the Juno mission at Jupiter, and concurrent Hubble Space Telescope images of Jupiter’s UV aurora. The combination of these measurements allow us to probe how the vast magnetosphere responds to changes in the external (e.g. solar wind) and internal (e.g. the volcanic moon Io) conditions. This project will exploit the available data to investigate the mechanisms and timescales of Jupiter’s magnetospheric dynamics.

    The successful candidate should hold a minimum of a UK MPhys Degree at 2:1 level or equivalent in a Physics-based subject. The candidate is expected to successfully work as part of a team, and to complete research suitable for the award of a PhD in Physics, including publications in high impact peer-reviewed journals.

    Please contact Dr Sarah Badman for further information.

  • Outer Planet Magnetosphere-Ionosphere coupling

     

    Supervisor

    Dr Licia Ray

    Description

    Jupiter’s upper atmosphere is connected to the local plasma environment allowing the two regions to exchange energy and angular momentum. We still don’t understand the mass flow out of the atmosphere though, which is directly affected by energy inputs into the atmosphere. This outflow can alter magnetospheric dynamics and modify coupling. We will address aspects of this interaction through the development of MI coupling theory and numerical models.

    The successful candidate should hold a minimum of a UK MPhys Degree at 2:1 level or equivalent in a Physics-based subject. The candidate is expected to successfully work as part of a team, and to complete research suitable for the award of a PhD in Physics, including publications in high impact peer-reviewed journals. 

    Funding is available on a competitive basis. Please contact Dr Licia Ray for further information.

Postgraduate Training

The Space and Planetary Physics group runs training workshops throughout the year that are dedicated to postgraduate students and also accessible to MPhys students who are doing their final year projects in the group. These workshops cover subject-specific and more general research skills.

The form and content of these workshops are determined through dialogue with PhD students so that the most effective training can be provided. These workshops are based on the needs of the SPP students but are also available to other postgraduate students. Postdoctoral researchers are also invited to attend these workshops in order not only to allow postgraduate students to benefit from the experience of our postdocs but also to provide further training opportunities for postdocs.

Additional training is offered by the Faculty of Science and Technology, ISS, and the Library. Our students also have the opportunity to participate in departmental outreach training and to develop their presentation skills via participation in the departmental outreach programme.

The group runs a fortnightly group meeting where recent research from students, postdocs and academics is presented and discussed. We also have a regular seminar programme with external speakers. Current research is also discussed in regular smaller informal discussions over tea and coffee. These are focused in research themes and we currently run "Gas Giant Gossip" and "Rocky Planet Roundup". Other academics also lead small discussions on more focused topics with their research students.

Recent workshops:
