Work experience week 2022

Study Physics in Lincoln

Last week the School of Mathematics and Physics hosted 5 work experience students from Lincoln University Technical College, Branston Community Academy and William Farr.

The aim of the week was to give a taste of what it would be like to study Mathematics or Physics at the University of Lincoln (or elsewhere), and for the students to gain some experience related to working in a university.

On Monday the students were given a tour of the University of Lincoln campus and the Isaac Newton Building in which the School of Mathematics and Physics is based. We also gave the students a very useful talk about the university application process and finances.

“We received some insightful information about how to make your
application stand out from other applications, how to know how much money you
will receive from loans and how to use student loans when living independently.”

On Monday afternoon…

Physics Film Night after the pandemic – 30/3/2022

IOP Lincoln Centre

On 30 March 2022 Lincoln School of Maths & Physics and the University of Lincoln Maths and Physics Society hosted the  Physics Movie Night, the first such event after the pandemic. It took place for most of its time in the Stephen Langton Building Lecture Theatre and finished for the last 10 minutes in our own INB3305 room in the Isaac Newton Building. The movie screened was Interstellar, which was the subject of discussion in our 3rd year Physics module “Physics of the Universe”. The night started at 6:30pm with a discussion and pizzas.

How to grow a moon

Dr Phil Sutton (Senior Lecturer in Astrophysics)

Most planets in our Solar System have moons orbiting them. The search is on to find moons orbiting planets outside of our solar system, known as exomoons, due to their potential for supporting life. But how do moons form and end up where we find them? This talk will consider some scenarios that can lead to planets having moons, like planetary impacts and gravitational capture.

Evolution of war and peace

Prof Bino Majolo (Professor of Social Evolution)

Scientists and philosophers have debated for centuries over the peaceful or aggressive nature of humans. This talk will present work from psychology, anthropology and animal behaviour to critically evaluate the extent to which our evolutionary past explains our aggressive or peaceful tendencies.

Maths & Physics Students Publish An Article On Exoring & Exomoons

Congratulations to current Mathematics student (Brayden Albery) and Physics alumni (Jake Muff) on their first research article. Both worked on small research projects during the summer, one of which was funded by Undergraduate Research Opportunity Scheme (UROS), to help understand the huge ring system thought to orbit the large exoplanet known as J1407b. The ring system was inferred by the unusually long and uneven transit when the planet passed in front of the star J1407, also known as V1400 Centauri. Previous work had shown that a gap in the ring could not be caused by an orbital resonance with a nearby exomoon, similar to how the Cassini Division is formed by the 2:1 orbital resonance with the moon Mimas (seen as the gap in the middle of the ring below).

The new research aim tot investigate if exomoons were able to form in the ring, which could then carve out a gap and is comparable to how the moons Pan and Daphne carve gaps in Saturn’s rings (below).

Simulations of the ring around J1407b as it orbited the star on a very elliptical orbit showed that it was not possible to form moons. The ring underwent significant disruption that hindered the formation of moons. However, an interesting feature was observed in one of the models. A gap did form in a similar location (0.4AU) in the ring where the original gap had been inferred from the transit.

Above: Four models of a retrograde ring system during their close encounter with the star. The eccentricity of the planets orbit increases for each row, and shows a greater degree of distortion. The right hand side gives the surface density of the ring.

Congratulations To PhD Student George Bell On His First Paper

A new paper by PhD student George Bell titled “The Gravitational Braking of Captured Moons Around Ringed Planets” has been published in the Journal of the British Interplanetary Society

The paper and project aims to investigate capture dynamics of irregular moons around ringed planets, with Phoebe and Saturn used as a real case study (below).


Irregular moons are a class of satellite found orbiting all of the Solar System’s giant planets: as their orbits do not match those of their planets, they are theorised to have formed elsewhere in the Solar System and were subsequently captured into their observed orbits. Missions such as Cassini have contributed significant empirical data on irregular moons in the present day but this paper aims to develop our currently limited theoretical understanding of their origins and capture as it presents one of the first projects to connect moon capture with another feature common to all giant planets: ring systems.
As a captured body gravitationally brakes around a ringed planet, it transfers orbital energy to the planetary system, a process which has been seen to leave distinctive signatures on the rings which may be used to constrain key parameters of this interaction, including the trajectory and timing. This paper presents a project which applies this technique to constrain scenarios for moon capture through conducting a series of computational simulations using the Python version of the astrophysical code REBOUND modelling the capture of the large irregular moon Phoebe by the planet Saturn and
Phoebe’s effect on Saturn’s ring system. By helping to constrain scenarios for moon capture, this research will further our understanding of the moon systems of the giant planets while simulating the effects of a moon’s interaction with a ring system by offering insight into the formation and evolution of planetary rings, whether within our own Solar System or orbiting exoplanets.
